For those who are getting a Periwinkle Sam ... what color combos are you planning for your build? I've ordered a purple Funky Monkey front cable hanger from Paul. Not sure it's going to be a good match. I have Phil Wood blue bottom bracket dust caps ... they'll probably match okay, not sure. The one that Riv built up for photos seems to be straight up gray-silver-black, and IMO it looks very nice.

Comfort 2. Braking performance 3. Asthetics 4. Price. I've used both of them extensively on brevets up to 600km. I no longer have the TRPs, but I have the Shimanos on several bikes, so I guess I've made my choice! I'm 5'6", 81cm PBH, and have mediumish skinny hands. I found the TRPs to be a combination of too wide and too long, though only marginally so. One thing to keep in mind with respect to reach is that the handlebar reach makes a difference, too. The reach on Noodle Bars is on the long side, especially compared to almost all current drop bars on the market. So, the combination of Noodle Bars and TRPs makes for an especially long reach to the brakes. To me that can be a feature, not a bug ... it allows me to have the bar tops comfortably near and high and still have a nice low, flat position in the drops. Aesthetically I very much prefer the Shimanos. I don't think I noticed any difference in brake feel, so I would guess the mechanical advantage is similar. Given that your first priority is comfort, you're probably going to have to try them both. Given that price is your last priority, you'll have no problem selling the ones you don't want on this list :-) Ted Durant Milwaukee WI USA -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Previously I have had a Bleriot, which is similar to the Sam. I rode the Bleriot on several very long rides, up to 600km, and never once wished I was on something different, with one exception. A couple of times I found that the steering geometry with a loaded handlebar bag was a handful on tight downhill corners. Interestingly, I have yet to experience a similar issue on the Sams, and I’ve done some pretty challenging downhill rides on them. Of course, I did auger in on one of those … a very tight switchback with some deep sand at the apex. I’m using 48mm (smooth) tires on my Sams, vs 42mm on the Bleriot, and I find the extra tire width to help in the twisties. Having knobbies might have helped prevent my crash, but also might not have. I think the main factor was operator error … pretty sure I was still grabbing some front brake too far into the corner. As I think of it, I have a pretty good comparison between the Bleriot and the Sam. I took each of them to Ireland, 5 years apart, and rode the same roads each time, including some steep climbs and winding descents. They felt very similar to each other, but I think the slightly bigger tires on the Sam gave me a bit more confident handling in the curves. Anyway, I would not hesitate to grab one of my Sams for a brevet of any length, and I have a Waterford custom-made for riding brevets. Why 2 Sams? Because one lives at my older daughter’s house in Portland ME, and the other lives at my younger daughter’s house in LA. How much do I like them? Enough that I’m thinking about getting a 3rd to replace my custom BreadWinner G-Road, which replaced my Bleriot because I wanted room for bigger tires and it has a bit steeper head angle and lower trail. It also has a 3rd bottle mount under the downtube, which the Sam is lacking. I have 16 1/2 hours to decide on this one.

Re: [RBW] TPU inner tubes - Anyone using them?
Another update. Found my Riv Road (622x32) had an almost flat front tire this afternoon. Pulled the tube and found no holes but a very slow leak from the valve stem. Using my fingers to grip the stem, I was able to back off the core then re-tighten it. The leak was worse. So, I gripped the valve with pliers and again re-tightened the core. As I worried would happen, when I went to reinflate the tube to check for a leak, the tube had broken at the base of the stem. That tire is now inflated by old reliable Schwalbe no 16. Out of the six tubes I bought in that size, I'm down to three usable. I like having removable/replaceable cores, but they're kind of silly on tubes that have such a fragile connection to the valve. The repair I made yesterday (Waterford ST-22, 622x32, rear wheel) didn't work. I pulled the tube again and checked for leaks in water, which I should have done yesterday. I'm not sure whether what I thought was a hole actually was, but I found a tiny hole in the same place relative to the valve stem, the other way around. The hole was so tiny that it was not at all visible - only could find it from the bubbles that came out of it under water. So, that one is patched and reinstalled. I've used Schwalbe superlight tubes on my Breadwinner (584x48) and had mostly good luck with them, though I did get a flat on that bike's maiden voyage. That was a special treat because it was my first experience with rims designed for going tubeless and I didn't know how hard it would be to get the beads off the shelves (and back on again). I'm going to experiment with superlight tubes on my Riv Road, where I think I'll benefit from them. Not sure I'll use them elsewhere.

Re: [RBW] TPU inner tubes - Anyone using them?
Further update. The patch on my 584x48 has held nicely, though I haven't ridden it yet. Meanwhile, the rear tire on my ST-22 (622x32) turned up flat yesterday. I took the opportunity to take out my Riv Road (622x32) and enjoyed a very fast (for me) ride. This evening I pulled the tube from the ST-22 and found a tiny hole. Exactly like the 584x48, I found a tiny bit of wire in the outer tread but not apparently poking through the inner casing. I patched and replaced the tube without incident. Alcohol wipe and Park glueless (MacOS still wants that to be clueless) patch, applied with the tube inflated. The fact that I've easily removed, patched, and reinstalled a couple of tubes strengthens my belief that the tubes that failed on installation were probably defective. It also gives me a bit more confidence in the tubes (and my ability to repair in the field) going forward. They sure feel good when riding. No word from RH on whether they're going to refund/replace the tubes I returned to them.

Re: [RBW] TPU inner tubes - Anyone using them?
Update here. I went for a couple of rides, total of 100km, on my new 584x48's. They certainly feel nice, and at that volume you really are dropping noticeable weight from each wheel. By the end of the second ride I was thinking the rear felt a little too cushy. A pinch test said there was still plenty of pressure. The next morning, though, the tire was completely flat. I removed the tube (quite easily, no issues), inflated it a bit, and it seemed to be holding air just fine. I thought that for sure I'd be able to see a hole in the clear tubing. I swept the inside of the tire and found nothing. So, mounted it back up (easy, no issues), inflated it carefully, and set the bike aside. A few hours later I checked and it had lost a lot of pressure. So, took it out again (easy, no issues), inflated it and started running it through a sink full of water. I finally found a very tiny leak. Checking the tire in that location I found a tiny bit of wire in the outer tread of the tire but couldn't feel it on the inside. Removed the wire, marked the leak location on the tube, wiped with alcohol (removing my mark in the process, of course), and after it dried put on a Park glueless (I like that my Mac autocorrected that to clueless) patch, praying I put it in the right location. I put on the patch with air in the tire, figuring it's best not to stretch the patch area too much. Installed again (easy, no issues), inflated, and set the bike aside. We'll see if the patch is successful. Even if it is, though, I think the "TPU tubes are less prone to flats" argument seems to be debunked. Which is too bad. I really want to like these, but the rationale is dwindling in my experience.

Re: [RBW] TPU inner tubes - Anyone using them?
Update on my experience. I continue to like the ones that successfully inflated on my 700x32 tires. Yesterday I took out that bike for the first time in a couple of weeks and the tires were quite soft. So, the tubes don't retain air as well as butyl, but it's not worse enough to be a problem. And I did a pretty hard ride and was pleased with how fast it ended up being. I also ordered some 650x48 tubes, but RH sent me 700x48. By the time they responded to my inquiry they were sold out of the 650's. Fortunately the next batch arrived pretty quickly and they promptly sent them to me. I mounted those today and once again needed 3 tubes to get 2 wheels done. These ones felt sturdier than the 700c skinny ones, but maybe it was just the extra width. Installation went fine, but as I inflated it the valve stem got sucked up into the rim. Weird! Deflated, checked for any snagging, and tried again, same result. Repeat, same result. So I decided to remove the tube and see what was going on. The tube came right out of the tire, minus the valve stem which this time stayed firmly put in the rim, fully detached from the tube. RH still hasn't responded to my inquiry about the two 700c tubes that failed, which I sent back with the mis-shipped tubes. After this one, at 3 out 9 tubes failing, I am well put off by these. I certainly wouldn't carry one as a spare ... I'd have to carry at least three to feel confident that in crappy field conditions and dead tired I'd be able to successfully install one. I also think that doing a patch in the field would be a roll of the dice - no way to be sure you could get the tube out without tearing it. I'm very interested to hear the experience of others. Could be user error. But I have over 50 years of wrenching experience, including 2 summers in a bike shop, so if these are beyond my skill level, it's pretty hard to see how these would be useful to anyone but a competitive rider with a budget (or product sponsorship) and highly skilled support.

It looks pretty snazzy with the red spacers and silver cogs. It's not going to win any awards for light weight, but I mounted it to a standard 8-11 speed freehub (using an extra spacer and cog to fill the gap), and it shifts beautifully with a Cyclone GT rear derailer and Silver downtube shifters. I didn't get any ghost shifting, but I also 1) tightened the shifter a bit and 2) didn't stand on the pedals. I had 39 and 42 chainrings in inventory, so I mounted those, as well. Ideally I'd have a 4-tooth difference up front, but this is good enough to test the hypothesis. I only did a quick neighborhood loop - flat, but with a fair amount of wind. My initial impression is that the steps are too small. Seems crazy, I know, but 10% steps feel small, and the ~20% steps in back feel only slightly too big. It feels amazing, though, to shift two cogs in back and get a huge change in effort. I played around with some alternatives, and I think 12.5% up front and 25% in back would be better for general riding (typical Wisconsin hills and wind, not trying to set Strava PRs). Any more than 6 cogs in back, though, and you'll be going to either a derailer dropper or a newfangled, ugly derailer with a big max cog clearance. If you're willing to go that route you can build a gearing setup with a massive range and perfectly even steps out of a 2x7.

Well, you might pick up a little speed if you’re at the front of the peloton going into the wind, but in the pack or downwind I suspect you’ll find you’re riding the same speed at about the same effort.

The rims are narrow Fir, and the tires are a pretty tight fit. I used levers to remove the tire but was able to reinstall without levers. New tires with only a few rides on them. So, I've needed 6 tubes to get 4 tires going. That makes the economics a little harder to justify. It also makes carrying a new one as a spare a bit of Russian roulette.

I have them set up, position-wise, very much like my “road” bikes and with Noodle bars. I wouldn’t hesitate to take them on a group ride, though I probably wouldn’t try to hang with the 25mph club. One thing to be aware of as you compare options is that Grant likes shallow seat tube angles these days. That makes it a little trickier to compare the handlebar reach with other bikes. (Don’t get me started on the bike companies that are now publishing “effective seat tube angle”.) I decided to set up my Sams with a bit less reach than my other bikes, so the back of the handlebars is just beyond my fingertips, rather than an inch or two. I don’t think you need to go all the way down to 32mm tires to make it zippy. I have 48’s on mine and that might be overkill, but I bet 38’s would be super fast and agile. (Decreasing tire size reduces both pneumatic and geometric trail and it reduces rotational inertia, all of which makes a bike feel “zippier”.) I saw the Periwinkle sample and am stupidly tempted to get a third Sam. But I also understand the curiosity about a true road bike. My Heron and Riv Road and Waterford ST-22 have around 33,000 kms on them since 2017.

I've ridden all my RH 32mm tires with Schwalbe SV16 tubes (and occasionally another 28-32mm tube that's been pressed into emergency service). I have not used latex tubes in quite a while. I used them on my Riv Road with some skinny tires and had two pinch flats on one group ride. Haven't used them since. Soon I will try TPU on my Breadwinner, which is 650x48B. They'll also go on my Heron (after it's back from the spa) and my Riv Road, both of which also ride on Stampede Pass tires. The big advantage of TPU over latex, in theory, is the air retention. I'll know how that's going in a couple of days. IMO, the question is whether TPUs are worth the substantial price premium over butyl. I've just "invested" a pretty big chunk of money into TPU tubes for 4 bikes. In terms of ride quality, my first impression is quite positive. TBD on the durability and flat-resistance.

But I do wonder…everyone says they offer so many hand positions; but I only see people with their hands on the hoods. Are riders really utilizing different hand positions? Great question. Racers and wannabe racers as I noted set up their bikes with a big drop from saddle to bars and a shorter horizontal reach to the bars. And they spend almost all their time on the hoods. I roam all over the bars. Today's 100km somewhat hilly, fairly windy ride was a great example. Heading out into the wind I spent a fair amount of time on the drops and hoods, but I was not riding at a hard effort (averaged around 22kph going out). Getting into the hills was a lot more time on the tops and the hoods, with a few standing climbs, working harder on the hills that got up to 15%. Coming home with a tail wind was a fair amount of time on the top curves, not riding too hard, enjoying the tail wind motor assist (and the net down hill). Also, I saw a pic of an albastache with brake levers in the middle of the bar. Would this mimic the freedom of hand position changes a drop bar offers? My experience has been that's not a great alternative. The wrist angles tend to be weird. I practiced tonight on my ride by grabbing the front of my Billie bars. It felt nice to be stretched out like that, but with no access to brakes or shifters from there I didn’t like to stay long. Unnerving. Understood! That's one reason why some people set up drop bars with cyclocross-inspired interrupter brake levers under the tops. I never have felt the need for that on road rides. If my hands are on the tops, I'm probably not going fast enough to need an immediate stop.

[RBW] Re: TPU inner tubes - Anyone using them?
I just received a box of tubes that I ordered from Rene Herse, so here's my 1-ride review. Bike and rider weight is about 70kg/150lbs. First impression ... they are crazy small and light. Clear plastic tubes with shiny metal valve stems and "Rene Herse blue" caps - nice touch! Unfolding them they seem fragile, especially the valve stem junction. I ordered some 700x20-32 and 650x45-68. I installed the 700c tubes on my Waterford, which has 32mm Stampede Pass EL tires on DT TK-540 rims with Velox rim tape. The rear tire is fairly new and had a bit over 500km on it. It had been reinstalled a few times (March is a bad time for flats in WI!). The front tire is a year old, probably has 3-4000km on it. Both tires come off the rim and go back on without tire levers. The tubes are a tight fit on the rim and have to be stretched a bit to get around the rim. The tires popped right back on, and I inflated to 60 psi to seat the beads, then backed off to 45psi. On the second wheel the tube/stem interface immediately cracked and I had to grab a 3rd tube. I don't know if that was a bad tube or user error. No tire lever, but it's possible I didn't push the stem up into the tire enough to ensure the tube wasn't trapped by the bead. Given how fragile they feel, it seems it won't take much to cause that to happen. First subjective observation - I can really feel the weight reduction handling the wheels. Noticeably less inertia around the perimeter. First ride was 100km of road riding across the north side of Milwaukee (urban riding) through the western suburbs and exurbs to some rural roads around Holy Hill. At 900m of climbing, it's a pretty hilly ride but not crazy. Some of the road surfaces are beautiful, freshly paved goodness. Others are, well, lunar. I often take my Breadwinner out there for its 48mm tires. Immediate second subjective observation is that the tires sound different. There's a "whoosh whoosh" that sounds like nice tubulars. Third subjective observation is that the bumps feel and sound different, more "thwip thwhip" than "thump thump". Third subjective observation is that it FEELS like the tires return more energy from deflection, whether from bumps or, especially, when swerving suddenly to avoid an obstacle or making a quick acceleration. I have no idea if there really is less hysteresis loss, but it feels that way. No flats today, but clear dry roads, even crossing the north side of the city, aren't usually an issue. So, I very much like the lightness and the feel of them, and the light blue stem caps are a nice touch that will look good on most of my bikes. I'm concerned about the fragility of the valve stem interface. No data or anecdotes, yet, on durability and ease of repair.

And right now, I’m heading out to do Tabatas training. I had to look it up. Promises to be the most miserable 4 minutes of my day. Wow, first we hear you are road bike curious, now you are doing tabata workouts. Leah is going super hard core on us. My 2 cents worth ... "road bike", as opposed to what you currently ride and love, is first and foremost about riding position. FWIW, my recommendation is to skip past Albastache and Mustache and go straight to drop bars. Start with them relatively high and close, so when your hands are on the tops you feel like your back is relaxed and comfy. Bernard Hinault, I think, said you should feel like you're playing piano on the tops. You then have the curves on top, where your hands are a bit wider apart and slightly forward, and your back should still be comfy. Then you go forward to the brake hoods. Now you should feel like you're more forward than you would be on your current bikes. But, if you're riding at a hard enough effort (we're not talking super hard here), the force on the pedals should be carrying enough of your weight that you're not having to hold yourself up on your hands. Next you go below the brake hoods to the farthest forward part of the drops. This is the speedy aero position. You won't have a low, flat back here until you've lowered your stem/bars quite a bit. But you should have a flat back and you should be putting a fair amount of force into the pedals. Finally, there are the flat parts of the drops, with your hands back a bit closer to you, which are a "cruising" location for me (and right next to my bar end shifters), low enough to be efficient but not fully stretched out. I've recently read comments from "racers" that if you spend any amount of time down there your bars are too high. Well, my bars are certainly too high by their standards, but mine are set up for me to be comfortable in every spot. Very important: in EVERY position you should not be gripping the bar or brake hood tightly, you should have a very loose grip and not be bearing too much weight there. I typically am very slightly pulling up on the brake hoods or drops to counteract the pedaling force of the opposite leg. Also, you should ALWAYS have at least a slight bend in your elbows in every position. If you are locking your elbows something is wrong with the position and you're doing bad things to your wrist and shoulders and neck. General rule of thumb for starting out, have the tops of the bars maybe an inch above saddle height or, if you're already pretty flexible in the heaps and low back, level with the saddle. Put the back of an elbow at the front of the saddle and stretch your finger tips toward the handlebars. They should just touch the back of the handlebars at the stem. Maybe a little closer if you're tight, a little farther if you're flexible. Somebody recommended Noodle bars, which I heartily endorse, as that's what I have on most of my bikes. I like them because 1) the curves are generous 2) there's a little rise in the top curve, making them very comfy in that area) and 3) there's a fair amount of reach and drop, so you have a good range of positions. That last part is key for me on long rides. Sometimes I'm riding hard and need the long and low positions. Sometimes I'm taking it easy and need the high and near positions. I won't opine much on "which bike", because once you figure out your fit criteria, any bike that allows you to have that position will work fine. I have my Sam Hillbornes set up almost identically to my custom Waterford ST and Rivendell Road, except on the Riv Road the handlebars are a bit farther away and lower.

[RBW] Re: Friction 9 V 10 speed
On Monday, April 15, 2024 at 8:27:21 PM UTC-5 ber...@bernardduhon.com wrote: Previous threads and literature suggests that the closer the cogs in 10 & 11 speeds makes for better friction shifting. What has been your experience? Like others, I have had mixed experience. A few observations - 1. On a very springy frame, derailer cables get yanked when you push hard on the pedals. I have a Terraferma that's so flexible even I can make it swing. I currently have some Cyclone derailers and Silver 1 shifters on that bike, with a 9-speed cassette, and there's no way I could tighten the shifters enough to keep it from ghost shifting if I do an out-of-the-saddle stoplight sprint. Other than that, it's a nice, smooth-shifting experience. It can be a little tricky to quiet the rear derailer when a cog is between clicks of the shifter. Which leads to ... 2. The reduction in derailer actuation (the ratio of derailer movement to cable movement) has been driven by the desire to have more cable movement per cog, to improve index shifting. The same effect can be felt with friction shifting, especially with shifters that use a micro-ratchet mechanism (like Silver). If the derailer requires only a small amount of cable movement to shift one cog, I find that the shifter can be between clicks, requiring one extra click then a slight shove forward. This gets pretty fiddly and would certainly be annoying if you're riding with the carbon folks or are oxygen deprived at 13k feet. Which leads to ... 3. The Simplex retrofriction bar-end shifters are absolutely perfect for shifting SRAM "exact actuation" (1.30 derailer actuation) derailers over 10-11 speed cassettes. The 1.30 derailer actuation requires a fair amount of cable pull, and the Simplex bar-ends pull a lot of cable. Being retrofriction instead of ratchets, you never have the problem of being between clicks. Don't go putting Simplex retrofriction downtube levers on your bike and think you'll get the same experience, though. The downtube levers pull much less cable. Bottom line ... you have to match your friction levers to your derailer and cog count combo if you want a system that works without a lot of fiddling. Not that fiddling is bad, necessarily. But you also should feel free to decide that indexing is better for your style of riding.

I did a quick look at some other bikes, and it appears the derailer hanger-to-first cog distance varies by quite a bit.

This is super important and where “YMWCV”! I should have prefaced my entire treatise by making it clear that most of my riding is in SE Wisconsin on mostly paved roads and crushed limestone trails. The limestone trails are abandoned railroad beds, so rarely exceed 2% grade. We have only a few hills that approach 20% and they are quite short. Mostly it’s rollers that are 5%, occasionally 10%. The wind, on the other hand …. Riding in the LA area, especially trying to go up avg 10% dirt/rocky trails that go on for miles, my gearing needs are somewhat different. One of the thoughts I’m keeping in mind as I spec a new bike is flexibility … if I travel with this bike, will I be able to easily modify the gearing/tires/fenders/racks/lighting to match the intended conditions. But then, I also have a few different bikes, so ultimate flexibility might not be paramount :-) > On Apr 3, 2024, at 12:33 PM, Bill Lindsay wrote: > > So, you have settled on what your gearing and derailleur choices will be?

All TBD, but I can confirm that a Vx GT and a Cyclone MkII GT will cover 9 -11 cog cassettes. In fact, a Cyclone MkII GT executes flawless index shifting on a 9-speed 12-36 cassette using Shimano 10-speed bar end shifters. I’ve posted elsewhere about this … SunTour derailers should index perfectly on a Shimano-SRAM n speed cassette with Shimano n-1 speed shifters, where 7<=n<=9. By “index perfectly” I mean that the horizontal derailer movement is exactly the right amount given the cable pull. An odd and interesting historical math artifact. What is also important is related to that. SunTour derailers have a high actuation ratio, meaning lots of horizontal movement relative to cable pull. As a result, “normal” shift levers are able to move a SunTour derailer across 8-12 cogs where other derailers would require a shift lever with more cable pull (a larger diameter drum around which the cable is wound). SRAM and newer Shimano derailers have much lower actuation ratios, driven (I hypothesize) by a desire to increase the amount of cable pull per shift and, consequently, increase the tolerance for imperfections in cable movement. Campagnolo, interestingly, _increased_ the actuation ratio slightly when they went from “old” 9 speed to “new” 9 speed and later. Always marching to their own beat, those Italians. My choice of shifters will depend on several factors, including the gearing, the derailer, whether I feel indexing is important, and whether I want to deal with the additional complication of handlebar-mounted shifters on a bike that might get rinko’d.

[RBW] Gearing Choices
that with 44/40 up front, and like me you ride 650x38b tires at 75-100rpm, you would have 18 distinct gears in a range from 49.5.kph to 7.6kph with an average step of 9.3% and a standard deviation of steps of 0.9%. Good luck building a 1x system with that range, step size, and consistency! And, good luck finding a 9sp 11-13-16-19-23-38-34-41-49 cassette! And, of course, if you want that setup you are forced to go with a butt-ugly modern derailer in back. The good news is you can use pretty much anything, including a stick, to shift up front! That said, a large number of cogs in back can allow for something of a nice combination of half-step and crossover. Some people talk of a “1.5 step”, but I’ve evolved to a bit different way of thinking about it. In theory, because of the cubing effect of wind resistance as speed increases, you should want progressively smaller gear differences as the gears get taller for a consistent difference in pedaling effort. In practice, I find this is true, to some extent, but the more relevant factors are hills and wind. In a nutshell, sometimes I want bigger gaps, and sometimes I want smaller. What I DON’T want, is to have a big difference in gaps smack dab in the middle of where I usually ride. And, sure enough, on one of my bikes, I am usually right near where the cogs go 14-15-17. That’s gaps of 6.9% and 12.5% right next to each other, and it’s a jarring difference. So my new, patent-pending approach, is to think of the rear cogs as essentially two ranges, close steps on the smaller half and larger steps on the larger half. If I’m in conditions where I want small steps, I stay on the smaller half; if I want larger steps, I stay on the larger half. In practice it’s very similar to a “half step plus granny” setup. It turns out, I have a bike that has an almost perfect example of this setup, and I have subconsciously been using it this way. An important part of this setup is that you cannot use the typical mindset of “maximize the drop from the big ring to the small” in current 2x setups. If you do that, you will probably take the gearing too low for the small steps to be useful. On the setup I have that works well, I chose to make the chainring jump less jarring than my other bike. A 42/26 combo is a giant 48% change. If I don’t shift at least two gears in back in conjunction with a front change, my cadence has to change way beyond my comfort level. A 44/32, on the other hand, is 32% and far more manageable. I have that on a bike with 650x48b tires and 11-32 11sp in back. That cassette is 11-15 in 1-tooth increments, then 17-32 in relatively even steps. If I cross over from the 44x15 to the 32x12, I have 9 gears that have an average 7.9% step between them (sd 0.9%). Staying on the small ring I have 7 more gears at an average 12.6% gap (sd 1.3%). Additionally, I can ride in the large chainring in the 44x17 at 28.7kph or 44x19 at 25.7 kph, the heart of my usual speed, and have consistent 2-tooth changes either direction in back. Or, I can ride in the 32x13 at 27.3 or the 32x14 at 25.3, with nice 1-tooth changes in either direction. The range total range is 9.6 to 51.0 kph for me. I’d want to get that down some if I was carrying a bunch of stuff off road in the mountains, but for riding around here that’s more than enough range. Back to my dilemma … the large cog of 32 and total wrap of 33 teeth in that setup are easily managed by a SunTour Cyclone GT derailer from the late 70’s. Be still my beating heart! No ugly modern derailer necessary! I still think a 2x7 half-step setup, with 18% gaps in the rear and 9% up front, is a killer setup for most road and gravel riding that doesn’t involve, say, more than 10% extended climbing grades. You’ll have to build your own cassette, though. A 2x11 or 2x12 two-range setup as I’ve describe above, though, is very practical and pretty widely available. Spreadsheet available upon request.

Re: [RBW] Re: [BOB] Re: Bump! ISO: 10-speed spacers. And question.
FWIW, the center-center spacing for Shimano cogs is: 7sp 5.00 8sp 4.80 9sp 4.35 10sp 3.95 11sp Road 3.69 11sp MTB 3.90 Sorry, I don’t have 12 and 13. Cog + spacer widths need to add to those numbers. Theoretically you can use thinner cogs than spec with wider spacers, but you would run into trouble with chain fit using thicker cogs with thinner spacers. If somebody finds or assembles a complete table of cog and spacer thickness spec’s, that would be a significant contribution to humankind. I’ll be posting on a related topic, soon.

The Gravel Kings require only a bit more effort than the RH tires. The Ultradynamico tires require noticeably more effort, but it's not like they're boat anchors. I've done a couple of 20mph rides on the Breadwinner. My Rivendell Road recently went from 26 to 32mm (though they measure 29 on the skinny rims) tires. It's easier to ride at 20mph on that bike, but only marginally so. What are people using to charge phones on long rides away from home? For my Breadwinner I spent a lot of time thinking about and designing a flexible generator-light-charging setup, and I'm very happy with the result. The coaxial wire from the hub ends in a quick-connector behind the fork crown. Normally my headlight (Supernova E3 pro 2) plugs into that, and the tail light plugs into the headlight. If I want to charge something, I have a Sinewave Revolution that can plug into the generator instead of the headlight. That leaves me without lights, but I also can plug the lights into a USB power source. Supernova says the lights won't run off a battery, but the 5v from the battery is more than enough. They aren't at their full brightness, but they are plenty bright for most conditions. I prefer having a headlight with a properly shaped beam (sorry, Beacon), and you can't really generate enough watts to run both a light and charge a phone, anyway. And besides, reasonably lightweight USB power sources are cheap and easy. The one I have is only a few ounces and can charge my phone 3x. And I can recharge it from my generator hub if I want. In fact, theoretically I can connect both the generator and the lights to the battery, and it will charge the battery as the battery is powering the lights. I haven't tested that to see if the generator makes enough power to run the lights and still add to the battery charge level.

I feel like the extra work required represents the mechanical "envelope" to get things perfect. On these forums (RBW, IBOB, 650B) I've advised that the typical home-mechanic should probably not take on Rene Herse Cantilevers, it's too heavy a lift. The second reason is that smooth post cantilevers give me more room to play with rim width. In the hands of the right mechanic, I think smooth post cantilevers are preferable. Such a great, thoughtful response, Bill. I encourage everyone to read it through, even though I've kept just a small part of it here. I had a laugh because Dia Compe 986 are exactly what I had in mind about impossible to readjust brakes. 20 year old me had them on both a Marukin Northstar and a Santana Elan. The Santana was especially challenging because Santana placed the mounts way too close together. They might have worked on a 5mm wide rim. The tandem was my wife's and my wedding gift to each other, and around our 30th anniversary I had Waterford do a full repaint and I replaced all the components with updated parts. Shimano CX-70 brakes were a revelation and for the first time I had fully confident braking on the bike. Wished I had them on our honeymoon, camping in Vermont! I hadn't thought much about rim width in writing my initial post, probably because I'd forgotten about the initial installation and choosing the right bolt/spacer combo on the CX-50s. But I don't think my mind is changed about the extent to which the Shimano CX system improves on smooth posts. On the contrary, the fact that I didn't have to think about that part of the setup when changing pads illustrates one of its advantages for me. Different length bolts and spacers would be compatible with the adapter I have in mind. Fortunately, having put 4 sets of CX brakes on bikes, I have a pretty good supply of spacers and bolts :-). I don't think the weight gain, if there is any, would be enough to change my mind. One thing that the CX and Rene Herse brakes have in common, that makes them such a pleasure (and so much easier) to work on, is the quality of the hardware.

[RBW] Smooth Post Brake Pads
Jumping off of Bill Lindsay's RoadeoRosa thread, where he commented on the varsity level work required to de-squeak his Rene Herse brakes I love Jan and his stuff, but I think keeping the smooth post brake pads for his brakes is being a slave to the past. I've never liked any of the brakes I've had that used them. Hard to set up, impossible to adjust after tightening (any aluminum bits immediately deform, preventing further adjustment), limited replacement options. I just replaced the pads on the Shimano CX-50 cantilever brakes on East Coast Sam. I wanted cartridge holders for easy pad swapping, prompted by a white-knuckle descent of Connor Pass in Ireland on a very wet day. I put on 105 holders with Kool Stop dual-compound pads, which I've loved on the Silver/Tektro long-reach side pulls I've had on various bikes. Setting them up took all of about 5 seconds on each side, and zero squeal out the gate. (Release the springs, do an initial install and slight tighten, then put a credit card between the trailing edge and the rim, squeeze the brake lever, loosen and re-tighten the pad, done. Don't forget to put the springs back on.) All of which made me dream up an adapter that would allow for mounting a bolt-on pad on a brake that uses smooth post pads. I'm envisioning a bolt on one end, to attach to the brake arm, and a flat tab on the other, with a hole for the pad mounting bolt to pass through. The tab probably wants to be offset from the center axis of the bolt, to put the inner face closer to the inside edge of the brake arm. A bit of Googling came up with zilch. Anybody handy with machining stainless steel rod stock? Ted Durant Milwaukee WI USA -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Yup, that is a beautiful bike! I know the feeling of being too stretched out, even as someone who is naturally quite flexible and likes to ride in a pretty low back position. My Sams are set up with a shorter reach than my other bikes and I have found I like it. Contrary to the others and to "conventional wisdom", I have not found saddle fore-aft position to be so critical that I have to nail it to the mm. I am comfortable and feel similarly powerful over a range of 15-20mm. My Sams have much shallower seat tube angles than my other bikes, and I have the saddles pushed forward a bit, but not a lot. Like a couple of other posters, I wouldn't hesitate to go to an 8 or even 7cm stem to get the reach that you like. I use my personal cubit to judge reach - put your elbow against the front of the saddle and see where your finger tips lie relative to the handlebars. Most my bikes have the bars about 20mm ahead of my fingers. On my Sams my fingers just touch the bars. As others have pointed out, Noodle bars have a pretty good reach. In addition, the TRP brake lever hoods are looong. The combined effect is quite a bit of extra reach. I very much like having lots of reach and drop on the bars so my position varies a lot as I move my hands. But it does mean you need a shorter stem so the on-the-hoods position feels neutral.

If you were to head back south to Monterey after that and head east you get the sort of smoothly paved roads that only a tiny and rich city like San Marino can manage. And then from there you can nearly get to Sierra Madre Blvd, which if you head north on, it will curve past Pasadena High and eventually lead you into Sierra Madre with a decent but gradual elevation change. Once you get to Sierra Madre you've got a good cafe stop at Syndicate. From my place in Glendale this is about a 34 mile round trip with about 1100 ft elevation gain but from Allez I'd guess closer to 25 miles. This is my default ride when I want to get some road miles in and the weather is mild enough that the coastal breezes are not a factor. I can confirm most of that, as I ride a similar loop frequently. Several of the roads are on Chuck Schmidt's monthly Velo Retro Rose Bowl ride. From Sierra Madre that ride comes back to the Rose Bowl via Paloma and Mountain. >From the Rose Bowl, you can head south on Arroyo (a lovely ride!) and pick up Monterey/York back to Allez LA. I just did a quick RWGPS check and that route, including one lap of the Rose Bowl, is 43km/27mi, with a bit less than 1000' of climbing, none of it especially steep. In addition to Syndicate in Sierra Madre, there is excellent pizza and a cafe across the street from Cub House. I may be time limited, as it's my last day here and I shouldn't abandon my family entirely. I can cut it short, though, and not do the full loop. If the group wants some non-technical dirt there's always some Griffith Park fire roads we can do instead. Those turns I know better from visual memory than I could adequately describe here. I've only been there once, so can't help lay out a route. Anybody know the conditions of the roads after the rains? If the group wants to experience the LA River Bike Path, please be aware that it is closed north of Los Feliz Blvd this month for some repairs. I'm not so big a fan of the river bike paths, other than a way to get from one part of the city to another. No shade, not much scenery. And yesterday I got screwed by one of them being closed unexpectedly. Had to hop a fence to get out and avoid backtracking a few miles.

On Monday, January 8, 2024 at 10:15:31 AM UTC-5 I wrote: The Heron Road bikes have .1mm thinner top tube walls than down tube, and my prototype has extra heavy stays, so there you go. A bit more on this, just for fun. I had Waterford build an ST-22 that is in many ways a duplicate of the Heron Road. However, it has a lighter top tube (.7/.4/.7 vs .8/.5/.8), a lighter down tube (.65/.45/.65 vs .9/.6/.9), and lighter chain stays (30x17 oval tapering to 12.5mm, 0.8 wall, vs 22.2 round tapering to 12, probably 1.0 wall). I find the Heron to be a nicer ride. BUT, there are a couple of other critical differences. Both bikes use the Heron round blade fork crown, but the ST22 has slightly longer (bit more rake, bit more clearance) but stiffer (1.2mm vs 1.0mm wall at the tips) blades. In addition, the ST22 fork has beefy fork ends for the SON SL connectors, and a Schmidt SON hub. Also, the ST22 rides on DT TK540 rims, compared to Mavic MA2 on the Heron. Someday I'll put the Heron's wheels on the ST22 and see how that changes things; I expect it will change a lot. Don't underestimate the importance of the fork to the feel and handling of a bike.

[RBW] Re: Why do some bikes just feel consistently faster?
Not to be overly contrarian, but ... Planing is a terrible word for the phenomenon in question, which is when the flex characteristics of the bike are such that the energy stored in deformation (of the frame and all the attached parts) is efficiently returned to power the rear wheel during the lower power part of the pedaling cycle. When a boat planes, it rises out of the water, resulting in a large reduction in coefficient of drag. The equivalent on a bicycle would be the development of a vacuum around the bike and rider at a certain speed. That would be fun, but it's certainly not what's happening on earth. Ironically, there is a well-known and used term in Jan's back yard, for the exact phenomenon he is trying to describe. Rowers have long used the word "swing" to describe a shell and oars whose flex characteristics synchronize well with their strokes, allowing them to go faster for a given power output. Jan claims that bikes that "plane" magically increase a rider's power output, but the reality is that bikes that swing well waste less of the rider's power. A better way to put it might be that such a bike puts more of the rider's power to the back wheel. The flex characteristics of the frame are important, of course, but the entire bicycle (and its rider) is a system of springs and in such a system the softer springs affect flex first, with the stiffer springs becoming more relevant as the forces increase. For most of us on this list, we don't spend a lot of time putting enough power into the pedals to get to the point where frame flexibility is significantly tested. At 57kg, I can tell you that I rarely put out that kind of power. I have a brevet bike made of .7/.4/.7 standard diameter tubing, and I can make that frame flex, but not for very long. That bike rides on 42mm tires at about 33 psi, and the tires are definitely the soft springs in that system. I don't attribute aluminum, or stiffer frames in general, to an increased focus on cadence. Track cyclists have always been obsessed with cadence. With the introduction of multiple gear systems for road biking came the opportunity to develop notions of "ideal" cadence. Note that when Jan talks about frames "planing" for him, he almost always talks about it working for his preferred cadence. Stiff frames, in fact, reduce the importance of cadence, as they reduce the contribution of the frame to swing (for a given power input). For me, cadence is only important when going uphill or into a headwind. It is important because I need enough momentum in my feet to keep a steady speed. Without that momentum, I am repeatedly accelerating during the power phase and decelerating during the non-power phase. That is terribly inefficient. And that is why, as discussed in the recent thread on gearing, it is so important to have low gears in steep hills. Long before aluminum frames were a twinkle in Gary Klein's eyes, cyclists talked about "staying on top of a gear" when climbing. It meant to maintain a fast enough cadence that you were pedaling smoothly, maintaining a constant speed. Cyclists have also long talked about using smaller gears and a higher cadence to "work your heart, not your legs." So, I also don't have _the_ answer to why some bikes seem/feel/are faster than others. Many of my best Strava times on climbing segments and my best 100km time are on my Heron prototype, which is a road frame but has the heavy rear stays from the touring frame. You can feel the weight of the stays (and the weight of the old SunTour freewheel) when you pick up the bike. Maybe it's just that I have so much invested in that bike that it inspires me to push a little harder. I tend to believe Jan's hypothesis that stiffness in the downtube and chainstays and flex in the top tube, relative to each other, help a bike swing in a way that returns energy to the rear wheel. Interestingly, old Reynolds tube sets were always spec'd that way, with thinner walls in the top tube than in the down tube. Somewhere along the way they switched to the Columbus standard, where top tube and down tube walls are the same. The Heron Road bikes have .1mm thinner top tube walls than down tube, and my prototype has extra heavy stays, so there you go.

I can make the 17th, but it’s my last day that visit, and I would prefer to keep some time for my family. I will be in San Gabriel, so would prefer to ride in the San Gabriel valley vicinity. I’ve had a few good rides in Cherry Canyon. The Cub House is a fun and funky bike shop in San Marino, near South Pasadena. They do builds for Rivendell, and it’s where West Coast Sam came to life. There is a fantastic pizza place across the street. Street parking seems to be generally available in the area, though I always bike there from my daughter’s place. The road ride to Cherry Canyon from there is nice, going across South Pas then up Arroyo to the Rose Bowl, then up into the hills along the amazing houses of Berkshire Ave. I tend to return back down Lida, past the ArtCenter College of Design. Lots and lots of up and down. Just one option, but I could also get over to the Griffith Park area, and I’d always love to find new routes. I’ve also ridden some around Griffith Park and loved it.

That's one of the reasons I love the Clem pedals ... plastic bodies, no pins, but the grip with the sneakers I wear is quite good. One of the things I took away from the Pino setup was the importance of matching shoes and pedals together. Even with cleat and binding systems, some shoes work better than others with a given system. Crank Brothers got pretty smart about that, creating a system of shims and spacers to optimize the fit. Binding-less pedals also have to be matched with compatible shoes. I've experienced a similar issue as Patrick, where the pins on a pedal don't line up nicely with the bottom of a shoe, and spent the whole ride trying to find a comfortable foot placement.

I started riding bikes in 1968. In 1978 I got my first pair of Detto Pietro shoes. I've been through cleats, Avocets, SPD, MKS Mapstage, Time ATAC, Egg Beater, and now I almost exclusively ride in sneakers (Lems) on flat pedals (mostly Riv's Clem pedals). The most efficient "directly attached to the rear wheel" system I ever felt was a pair of Delrin cleats that Pino Morroni machined for Grant. They snapped perfectly into Campy NR pedals, and you didn't even need a strap unless you really pulled straight up on them. All the systems that "float" were absolutely terrible for me. My heels would rotate to the float limits, creating a large amount of rotational strain on my knees. I found Egg Beaters with zero float cleats to be the best for my needs, and I still have them on my Riv Road, which is set up for fast group riding. Also, like Wesley, my wife and I find cleated pedals to be very important on the tandem - no more feet flying off the pedals at inopportune moments. I liked having cleated pedals and shoes for the short downtown part of my commute, where I would often need to accelerate hard to keep up with the traffic flow. Since I retired I haven't had a single time when I've been clipless (meaning no binding system at all!) that I have wished for something holding my feet to the pedals. On the contrary, I am finding that my feet, ankles, knees, and hips are much, much happier, especially on long rides. I love being able to shift my feet forward and back, sometimes on the ball, sometimes the arch, depending on the terrain and the level of effort. My father-in-law started doing some more recreational biking in his retirement. The shop that sold him a new bike insisted he needed toe clips and straps. At an intersection with some sand on the pavement (April in Wisconsin!) he used his front brake and went down. In trying to pull his foot from the pedal he very badly tore up the ligaments in his knee. Needless to say, when he got back on the bike the next year, I had tossed the clips and straps.

My friends were hard core xc skiers in college, and they had a hard time keeping up with old French guys. Side note - that "route profile" at the bottom of the YouTube video is a histogram showing the relative amount of viewing time of each segment ... sort of a "popularity" measure of the segments. I like Andy's suggestion, though, that it's a metaphor for a person's life. Plenty of ups and downs. My cycling goals that I set for 2023 were "Ride a lot. Enjoy it all."

I found that 2.1" Marathon tires were deadly in slush. They had just enough float that at any speed above walking pace the front would float up off the underlying pavement or ice/snow pack, and the traction then would match the mythical frictionless surface of physics. With all the salt that is used on roads here, temps can be pretty well below freezing and we still have mostly slush, so I found that skinnier tires worked much better. Unfortunately, that means that when dealing with frozen ruts, there's a lot more bone shaking going on.

There’s a slight learning curve to getting comfortable shifting a triple, but with the right combo of chainrings and front derailer, it should work reliably. Grant has written a good description of how to get reliable shifts, but it presumes the mechanical things are set up correctly. Also, if you are going up a really steep hill, you might not have a half revolution worth of momentum. Imagine the circular pedal path as the face of a clock, and shift at 4:30. That’s half of your success. When your shifting foot is at 6:00, stop muscling the pedal entirely. Let it drift to 12:00. Call this ‘floating,’ and it’s the other half of success. As you float that pedal to 12:00, you also have to float the other side pedal to 6:00. The point is to eliminate power for half of a pedal revolution to de-tension the chain and give the shift time to take. When you honest-to-goodness float the pedal after the shift for, it takes just half a stroke. If you apply power even though you're not supposed to, the shift goes to hell, you lose your momentum, you fail.

The "standard" chainring gap became 16 teeth when "compact double" 50x34 combos became all the rage. That's a 39% jump, the way I measure it (Ln(50/34)), or about 2.5 times the 15.4% jump from 18 to 21 in back. Now, if you keep that 16 tooth gap but go down to 40x24, that's a ginormous 51% jump, which is 3.3x the 18-21 jump. I have a 42x26 on my Waterford ST-22, and it's definitely jarring to drop to the small ring when you hit a hill, requiring a bit of advance planning to shift a cog harder in the rear, first. I spent plenty of time riding half-step gearing, so I'm facile with double-shifting, but after a couple hundred kms I'm too tired for that. For my Breadwinner G-Road I went with 44x32, which is a gentle 32% jump. It means there's more overlap in the gearing, or to put it another way, I'm not maximizing the total range of the system, but I very much prefer to make that trade-off. At 41%, the 14-tooth gap on the Silver 42x28's on my Sams is pretty much the outer limit for me. The Wide-Low (38x24) is a 46% jump which is pretty high.

I'd want to hear more about what you mean by "lots of hills" and the kind of riders (not just their gear) you are with. You mention in a follow up riding up Mt. Diablo, for example. So, that to me says "sustained paved climbing at a mostly moderate but sometimes steep grade", unless you went to the top, in which case I'd add "sometimes wicked steep". I'd also want to hear more about your fitness level or, maybe more specifically, the speed at which you and your riding pals like to climb. I'm a lightweight, not especially strong rider but I like to push myself going up hills. I don't often find I need easier than a 1:1 gear; if I do, I'm off road on some VERY steep stuff. I don't worry too much about how big my biggest gear is, although riding with a good group can mean wanting some bigger gears. My general statement is that I'd rather be coasting down a hill than walking up it. I've been very happy with the 42x28 Silver cranks on my two Sams, with 32 or 34 tooth big cogs in back. I've been surprised at how many hills on which I've actually been able to stay on the 42. On the other hand, I have a Rivendell Road with a classic 53x39, 13-26 setup for the rare fast group ride. I did a super hilly group century on that bike ... it was a fast result, but it had a lot of out-of-saddle grinding time. I am a dedicated handlebar bag user and don't generally carry more gear than can fit in one, even for very long rides. Also, I am a big fan of Noodle Bars. I have some back issues (a couple of compression fractures) but I'm still pretty flexible and find that putting the tops of the bars level with the saddle and not too far away gives me the best combination of power (what little I have), several riding positions, and long-distance comfort.

West Coast Sam waited patiently and rewarded me with a lovely ride up and down Cherry Canyon Motorway, with some bonus time in the hills above the Rose Bowl.

[RBW] Tree Sap

East Coast Sam lives in Portland, ME, and recently I was surprised by a very sticky water bottle. At first I thought it was just some of my liquid fuel, but it turned out to be pine sap. There was sap all over the underside of the bike and even on my tail light. My son-in-law had just been to a car wash where they recommended liquid Purell hand sanitizer for removing sap from his car. I used it on the bike and. it was amazing - melted the sap like magic.

I’ve never tried Bombas - should I? Smartwools never wore well, and would shrink up and the tightness in the forefoot aggravated my bunionettes. I also spent time in Darn Tough socks ... better than Smartwool, but Bombas are softer, looser knit, and the forefoot stays reasonably loose. Lately I've also been trying and liking Injinji socks with separate toes, which are really good for keeping my forefoot from being overly constricted.

Well, this was taken 11 years ago, but I'm sure I'll be wearing the same thing soon. Lycra shorts from Aerotech, Rivendell LS wool jersey. Socks these days are mostly from Bombas, not Smartwool. Shoes aren't shown ... for that bike, my Rivendell Road (Joe built/Joe painted), I still go with bindings, so shoes would be Lake MX-1. This photo was taken on an unusually warm Thanksgiving Day. In lower temps I'd probably wear my MUSA or Rene Herse knickers over the lycra shorts. The Riv Road doesn't have a handlebar bag so a jersey with rear pockets is usually needed. On a big with a handlebar bag I would just wear a Smartwool lightweight half-zip if it's not too cold. Sunny and upper 70's here this week ... I'll still be wearing SS polo shirts or LS seersucker.

[RBW] Aging cyclists (was upright bars and geometry)
On Wednesday, September 13, 2023 at 8:41:29 AM UTC-4 rmro...@gmail.com wrote: Garth, of course nothing you say here is wrong, it’s simply not the same for everyone. And I know you know that. I am a 68 year old lifetime cyclist. I’ve been through many drop bar bikes and though my last one (Custom Richard Sachs) was easily the best, I was never truly comfortable. This is a timely topic for me. I'm about to turn 61 and, until last spring, I thought I had dialed in my perfect bike fit. Doing a fair amount of yoga starting in my 40's really helped my flexibility and core strength, so I ride with a pretty low, flat back. I use pretty deep drop bars (mostly Noodles), set the tops a bit below the saddle, and spend a lot of time on the drops. My personal cubit is how I check seat-bar distance, and the backs of my handlebar tops at the stem have always been 2-4cm ahead of my fingertips. When I was spec'ing out my new Sam, I spent a long time on stem length and finally decided to go shorter. This is also relevant to the previous thread, as the Sam has a much slacker seat tube angle than my other bikes, making it a bit more challenging to translate fit from the other bikes. On the Sam, the bars are just a few mm ahead of my fingers. I was worried this would be too cramped, so it was a bit of a revelation when I found it was comfortable and still allowed plenty of breathing space. Thinking about it, I realized that it was logical that my seat-bar distance would need to shrink a bit. I have pretty severe osteoporosis and a couple of compressed vertebrae, so my torso length is shorter than it was 5 years ago. So, yeah, everybody ages differently, but we all age and need to be aware of how our bodies are changing and how that impacts position and fit on the bike.

[RBW] Re: upright bars: how does shorter or longer stem affect steering?
On Sunday, September 10, 2023 at 4:59:17 PM UTC-4 eddietheflay wrote: My current bike has Billie bars installed on a very tall adjustable stem. Effective top tube on this bike is 59.5cm. Reach to both the rear portion at the grips and front portion at the curves seems quite comfortable. But when steering from the grips things seem really twitchy. Wondering if a shorter top-tubed bike with a longer stem would make things more steady? My experience with a Quickbeam was similar - upright bars (Albatross) and using the ends of the bars made for a very quick, "twitchy", light steering feel. I attribute this to two factors. The first, and IMO more important one, is that my position on the bike was far more upright, resulting in much less weight on the front wheel. The second is that my hands were much farther from the steering axis. So, if a shorter top-tube and longer stem results in a) your position being the same, and b) moving your hands closer to the steering axis (which it would if on your current setup your hands at the ends of the bar are behind the steering axis) then I'd expect a slight reduction in twitchiness. I'd expect it to be maybe imperceptible, though, because the change in hand distance to steering axis will be tiny, as the bigger factor in that regard is the handlebar width. Hand distance from the steering axis does two things. First, it gives more leverage, so less effort is required to put an equal amount of force into turning the fork or (what's really important) changing the angle of the bike relative to the ground (or resisting other forces trying to change the angle to the ground). Second, the flip side of that, for a given amount of fork rotation (or body/bike/ground angle changes) your hands have to move a greater distance. It's worth noting, only because some things I've seen written seem confused on this issue, that if you change the stem length and also change the bars, such that your hands wind up in the same place relative to the steering axis, you will have zero change on steering feel. You can put a 1000mm stem on there and super long backward reaching bars and your leverage won't have changed. The amount of flex in that system will likely have changed though, and that could impact "feel" in other ways.

What seats, trailers, etc did you use? Where did you ride? Mind you, this is 30+ years old ... we put our daughters in their car seats in our Burley trailer to start, about 1 year old. Got hit by a car once, luckily a very slow motion event, 90+ year old making a left turn from a 4-way stop pushed us into the curb. Nobody hurt, and I felt pretty good about the overall safety of the setup, but of course a higher speed incident would have been much different. We also used a rear rack mounted seat, but I never liked that setup; terrible balance and a much bigger distance to fall if the bike goes over. We rode lots of places around Milwaukee, using the bike path as much as possible, quieter public streets elsewhere. The trailer lasted well into childhood for our two daughters. Most important thing was that every ride had to be about the food. We still have it and are hoping our grandchildren will ride in it soon.

In a food processor, start with the dates (be sure there are no pits!). When they're well chopped, add the hazelnuts and blend until you have a fairly moist ball. You want to release a bit of the oil from the hazelnuts, but not completely into a butter. Then add the chocolate and run it just long enough to blend in. It will be getting pretty warm at this point and you don't want to overheat the chocolate. Scoop out and form balls, whatever size you like, but I aim for something a bit smaller than a golf ball. Roll the ball in coconut flour and set aside to cool and harden. They stay remarkably solid even in a warm handlebar bag, but if you put them in a pocket you'll probably have a mess.
