Deacon, I am glad that you were able get your brakes to work the way you want. I suspect you were told the opposite of what I am telling you, and that you understood what they were saying. Sadly they told you wrong. But happily they still steered you to something that worked for you. The phrase slushy brakes suggests to me low effort producing large brake lever travel with little braking effect. If that's what you had it was likely due to elasticity in the brake system, which is a separate thing from leverage. If you experience that sort of thing, look for what moves when you squeeze the lever hard after the pads hit the rim. For example, I found the steel front cable hangers flex a lot.

Re: [RBW] Re: Paul Brakes -- Wow!
Deacon, I agree with you on this. Getting the straddle as close to 90 degrees has always been the position which yielded the greatest stopping power for me. With my neo-retro's (Aka the 'weaker' of the paul canti's) I have the cable long and up high, and I have enough power to lift up the back wheel if I really wanted. Lower straddle usually results in less power, and obviously less mud clearance as well. As I understand it, the idea is to get the cable as close to 90 degrees as you can WHEN the brakes are in contact with the rim. To read a much more exhaustive explanation than I'm willing to regurgitate, take a look at BQ's great write-up on setting up canti's. In the end, I'm sure we can all agree that Paul canti's are awesome.

Re: [RBW] Re: Paul Brakes -- Wow!
I learned this over 20 years plus of using and working on cantilever brakes. I set up brakes for mountain bike race teams in the late 80's and early 90's. I am sorry, but your armchair theory does not translate to real bikes in my experience. I run canti's on my Crux. The greatest feel and max leverage is at 90 degrees. On Friday, February 20, 2015 2:34 PM, ted ted.ke...@comcast.net wrote: Clayton, Your reasoning is mostly wrong, and your stick analogy does not apply.I think you are forgetting that the straddle wire provides mechanical advantage. A small side force on a relatively straight cable produces a large tension in the cable. In theory, if the cable is straight the leverage is infinite. If you correctly analyze any cantilever brake setup you will find that making the straddle wire flatter increases the net leverage. Unless of course the cable attachment point is at or below the pivot, but I don't think anybody makes brakes like that. On Friday, February 20, 2015 at 10:26:03 AM UTC-8, Clayton wrote: I have to jump in here.. I have always been taught and discovered on my own, that the straddle cable should be as close to perpendicular, or at 90 degrees, to the center of the brake pad lever when it hits the rim. You can do this experiment on your own. Get a stick. Tie a string to it. Lay the stick on the ground and lift the string. Lift perpendicularly and then from different acute angles, inline with the stick. If you lift from acute angles, the stick slides, which is energy wasted. If you set up your brakes with a too short straddle cable, you lose feel and the leverage forces change as you apply the brakes. Starts out soft and weak, and increases as you apply the brakes because the angle gets closer to 90 degrees. Over 90 degrees, and you get weak brakes. The brake arm is just a lever. It works best, like all levers if you lift from the end at 90 degrees. The brake arm pivot placement is basic too. Long arm on the straddle cable side, shorter arm on the rim side. It does not matter at all when it comes to straddle cable length. The only lever the straddle cable acts on is the long side. The distance between the pivot and rim, and pivot and straddle cable angle is fixed and you can't change it. After 20 years plus of running cantilevers and being a mechanic for YETI cycles back in the heyday, a shop manager and mechanic, I finally gave up. I run V-brakes now, which are much more powerful, especially with long Cool Stop salmon pads. Braking is at near disc power. I can easily do a nose wheelie, using brake power alone. The feel is so good, I can anti-lock brake the front. Apply, feel it start to slide, let loose and rebrake. The only thing I don't like and it is very minor, is the hood shape on the Cane Creek Road V-brake levers. There is far more clearance with panniers and I don't poke my calf anymore. Everyone here loves their cantilevers. They are prettier and match the aesthetic of Rivendell. I get that, but for me the superiority of V-brakes has become beautiful in itself.

The the vertical component of the tension in the straddle cable is equal to the tension in the brake cable (well half on each side).Lengthening the straddle cable reduces the tension in it as well as changing the angle at which it meets the brake arm. The vertical component of the tension stays the same, and the horizontal component is decreased.The net result is less torque around the brake post for a given force on the brake lever.For a wide profile brake like the 720, where the end of the arm is barely above the pivot, the decrease in leverage is relatively small. But it is a decrease, not an increase. To get an increase in leverage by lengthening the straddle cable the end of the brake arm would have to be below the pivot. Again I'm not claiming that the longer straddle cable didn't work better for you, just that the cause of the better can't have been increased leverage.

[RBW] Re: Paul Brakes -- Wow!
Clayton, Your reasoning is mostly wrong, and your stick analogy does not apply. I think you are forgetting that the straddle wire provides mechanical advantage. A small side force on a relatively straight cable produces a large tension in the cable. In theory, if the cable is straight the leverage is infinite. If you correctly analyze any cantilever brake setup you will find that making the straddle wire flatter increases the net leverage. Unless of course the cable attachment point is at or below the pivot, but I don't think anybody makes brakes like that. On Friday, February 20, 2015 at 10:26:03 AM UTC-8, Clayton wrote: I have to jump in here.. I have always been taught and discovered on my own, that the straddle cable should be as close to perpendicular, or at 90 degrees, to the center of the brake pad lever *when it hits the rim*. You can do this experiment on your own. Get a stick. Tie a string to it. Lay the stick on the ground and lift the string. Lift perpendicularly and then from different acute angles, inline with the stick. If you lift from acute angles, the stick slides, which is energy wasted. If you set up your brakes with a too short straddle cable, you lose feel and the leverage forces change as you apply the brakes. Starts out soft and weak, and increases as you apply the brakes because the angle gets closer to 90 degrees. Over 90 degrees, and you get weak brakes. The brake arm is just a lever. It works best, like all levers if you lift from the end at 90 degrees. The brake arm pivot placement is basic too. Long arm on the straddle cable side, shorter arm on the rim side. It does not matter at all when it comes to straddle cable length. The only lever the straddle cable acts on is the long side. The distance between the pivot and rim, and pivot and straddle cable angle is fixed and you can't change it. After 20 years plus of running cantilevers and being a mechanic for YETI cycles back in the heyday, a shop manager and mechanic, I finally gave up. I run V-brakes now, which are much more powerful, especially with long Cool Stop salmon pads. Braking is at near disc power. I can easily do a nose wheelie, using brake power alone. The feel is so good, I can anti-lock brake the front. Apply, feel it start to slide, let loose and rebrake. The only thing I don't like and it is very minor, is the hood shape on the Cane Creek Road V-brake levers. There is far more clearance with panniers and I don't poke my calf anymore. Everyone here loves their cantilevers. They are prettier and match the aesthetic of Rivendell. I get that, but for me the superiority of V-brakes has become beautiful in itself.

The the vertical component of the tension in the straddle cable is equal to the tension in the brake cable (well half on each side). Lengthening the straddle cable reduces the tension in it as well as changing the angle at which it meets the brake arm. The vertical component of the tension stays the same, and the horizontal component is decreased. The net result is less torque around the brake post for a given force on the brake lever. For a wide profile brake like the 720, where the end of the arm is barely above the pivot, the decrease in leverage is relatively small. But it is a decrease, not an increase. To get an increase in leverage by lengthening the straddle cable the end of the brake arm would have to be below the pivot. Again I'm not claiming that the longer straddle cable didn't work better for you, just that the cause of the better can't have been increased leverage.

Re: [RBW] Re: Paul Brakes -- Wow!
Mark, From the BQ writeup you cite The angle of the straddle cable also af- fects the mechanical advantage. A low straddle cable means that the pads travel less for a given brake lever pull. Less travel means more power. and Unless the straddle cable is at a right angle to the brake arm, the effective length of the brake arm is shortened, which in turn reduces the braking power. The first is pretty straight forward, but the second overlooks the fact that, for a given brake, the tension in the cable changes when you change the angle. As you raise the angle towards 90 you reduce the tension which counteracts the increase in effective length. I think its much simpler to work out if you decompose the cable tension into vertical and horizontal components and stay away from notions like effective length.

[RBW] Re: Paul Brakes -- Wow!
It's good for big-foot heel clearance, too. I have Tektro 720s on the front of my Quickbeam, and the original low-profile brakes on the rear. The rear CR720s hit my foot sometimes, so I switched that brake back to stock. I'd call the CR720s pretty (I like the look more than the Pauls), and adequate with a high straddle carrier and Kool Stop pads. I'd do Patrick's Paul setup, but I gathered from list eavesdropping that it's hard to make the M12 rack work with them. And I love that rack.

Re: [RBW] Grant Petersen's views on mountain bike development?
Went out for some real mountain biking yesterday morning. Challenging single cross with lots of climbing (and walking for me). (Trail info: http://rideoregonride.com/mountain-biking/syncline-trail/). I rode my Koga Miyata Valley Runner (early 90's rigid mtn) with albatross bars and barcons. Also, I had a Hobo handlebar bag and tires were the Compass 26 x 1.75 (Pasela style tread pattern). In general, I love riding this bike, but it was way out of its element on this terrain. Climbing was easier with hands forward on the bars rather than at the grips, but then I didn't have access to shifting and brakes, which in tricky terrain like this is essential. I often bumped the barcon with my knee and was quickly cursing bar-ends for tricky terrain. This bike in its current set up is great for dirt roads, fire trails, and cruising around, but it's no mountain bike. Knobby tires would certainly improve things quickly, but the Albatross bars aren't great for real mountain biking, at least for me. And the bar ends weren't working well either. For real mountain biking I would much prefer a bullmoose style flat bar or at least a Moustache or Albastache to get my hands further forward to help with climbing while maintaining easy access to the brakes if not the shift levers. So based on my experience I agree with Mike about the handlebars at least. I still had a great time.

[RBW] Re: Paul Brakes -- Wow!
I also appreciate how easy it is to rebuild Paul's brakes. All the parts are available at a reasonable cost. Last a life time. Once you get past an initial learning curve they are pretty easy to adjust and hold their adjustment very well. Many years ago, while commuting home I was involved in a crash which was largely caused by a pair of inadequate Shimano cantis (and a crazy women in a pick up truck.). After that I switched to a pair of neo retros. Soon after that I was staring at a car that had made a right turn directly in front of me. The neo retros lifted the rear wheel off the ground but stopped the bike on the spot. I've never considered any other brakes since. Worth every penny.

Plenty within walking distance from RivHQ. Ride a bike to BBH super down the street. Ask for directions to Grant's Hills or Shell ridge. Make sure you stop by Leonias a couple blocks away from BBH and get a hot chocolate. My favorite close food options is Havanas Cafe for breakfast, Breakfast burrito is a good staple.

Re: [RBW] Re: Paul Brakes -- Wow!
Ted, Envision one half of a cantilever brake setup. There is an axis between the points where the straddle cable attaches and the brake pivots. We'll call this The Axis. Now envision a force vector along the straddle cable. If you conceptually break down that vector into components which are 1) perpendicular to The Axis and 2) parallel to The Axis, you will realize that any force parallel to the axis will be working against the rigidity of the cantilever brake mount. So, you really want to maximize former vector component... that is, by applying the straddle cable's force perpendicular (90 degrees) to The Axis. The iron cross analogy of infinite tension doesn't really work when you consider the brake pivots (and the steel frame to which they attach) resisting most of that tension.

I worked at a Brompton dealer for a while. Even though it was a ~$200 upcharge over normal paint, one of the most popular finish choices was essentially the same finish, what they called raw lacquer. The rep once explained to me that the upcharge was not because the finish cost more than normal paint or powder--although it did require extra rust protection treatment--but because the brazing on those frames had to be super clean, since it would be on display for all the world to see! Thus, it's interesting to see the clearcoat treatment on a frame that wasn't originally intended to be clear coated..gives you a sense of what finished brazing looks like at the production level.

The paint was badly scratched, chipped, and showing a couple surface rust spots. 1) I had it bead blasted to remove the paint. 2) My friend Andy brazed on some eyelets (the KOM, as a racing frame, had none). 3) I had it bead blasted again to clean up after the brazing. 4) I had it painted with 2 coats of automotive clear. My local powder coater was afraid his clear coat would still be a bit milky, so he hooked me up with a painter instead. I think it turned out beautifully raw. I love being able to see the bra zing. The lugs are simple and very clean, but the fork lug is pretty messy in comparison. Then again, it's a weird lug and looks like it needed a some fillet work. The curious part is, there is some sort of copper or bronze on the bottom of the head tube. It lasted through two bead blasts, so it's not rust. I think it's a gorgeous detail, but it's weird. I retired the original Uniglide wheels, and gave my Schwinn the wheels off my '05 Cannondale (for now). I'm really tempted to get a dynamo wheelset, and this one is very tempting http://www.bike-discount.de/en/buy/shimano-custom-made-wheelset-26-with-dynamo-dh-t780-mavic-xm317-52011/wg_id-507 for less than $200. I had broken the original XT derailer a couple months ago, so I found a 9-speed XT RD and installed matching 9-speed Shimano bar-end shifters. The bar wrap was matched to the Captain America original paint, but the blue still looks good. I may try dark red or green next. I can gush about the Schwinn KOM http://mombat.org/MOMBAT/Bikes/1988_Schwinn_KOM.html (and it's older brother, the Paramountain). If you ever see one that fits you (and your N+1 equation), buy it. Ned Overend rode the Paramountain to a NORBA championship, and gave design input. It has great 71/74 geometry and is comparable to an MB-1. Mine is 22 x 24 (56 x 61 cm) of MUSA, lugged, lightweight steel! I lucked out and found this one on my hometown's Craigslist for $75. I've been very lucky with my local Craigslist! I scored this, my Riv, my Giordana gofast, and a 90s Univega for my girlfriend that I built up like I've built this KOM. Everything is original except: wheels, tires, Nitto B135 bars, TRP brake levers, Nitto Dirt Drop 8 stem, 9 speed shifters and RD, pedals and seat. I use a Nitto M12 and Carradice SQR to carry a Sackville Small Trunksack and Carradice Nelson, respectively. Bell and mirror, of course. Now that I have rack mounts, I will probably try out some camping setups this summer. I love love love how this bike rides; it's a tight race between the KOM and my Rivendell for the most ride time (in fair weather). The fast 2 tires (ITS MK2) make it great for the potholed streets and curbs on my commute, and it really flies on the limestone gravel back roads in Iowa's river valleys.

Re: [RBW] Re: Paul Brakes -- Wow!
Of course you should like what you like, and may believe whatever you like. However as it seems you realize, good brakes are about more than just mechanical advantage. Though your experience has taught you that 90deg. gives the best brakes it does not follow that 90deg gives maximum mechanical advantage. On Friday, February 20, 2015 at 3:09:18 PM UTC-8, Clayton wrote: Oh... I forgot to mention that brake feel is more important than outright power anyway. Bikes have a small contact patch.

I think you are forgetting that the straddle wire provides mechanical advantage. A small side force on a relatively straight cable produces a large tension in the cable. In theory, if the cable is straight the leverage is infinite. If you correctly analyze any cantilever brake setup you will find that making the straddle wire flatter increases the net leverage. Unless of course the cable attachment point is at or below the pivot, but I don't think anybody makes brakes like that.

I have always been taught and discovered on my own, that the straddle cable should be as close to perpendicular, or at 90 degrees, to the center of the brake pad lever *when it hits the rim*. You can do this experiment on your own. Get a stick. Tie a string to it. Lay the stick on the ground and lift the string. Lift perpendicularly and then from different acute angles, inline with the stick. If you lift from acute angles, the stick slides, which is energy wasted. If you set up your brakes with a too short straddle cable, you lose feel and the leverage forces change as you apply the brakes. Starts out soft and weak, and increases as you apply the brakes because the angle gets closer to 90 degrees. Over 90 degrees, and you get weak brakes. The brake arm is just a lever. It works best, like all levers if you lift from the end at 90 degrees. The brake arm pivot placement is basic too. Long arm on the straddle cable side, shorter arm on the rim side. It does not matter at all when it comes to straddle cable length. The only lever the straddle cable acts on is the long side. The distance between the pivot and rim, and pivot and straddle cable angle is fixed and you can't change it. After 20 years plus of running cantilevers and being a mechanic for YETI cycles back in the heyday, a shop manager and mechanic, I finally gave up. I run V-brakes now, which are much more powerful, especially with long Cool Stop salmon pads. Braking is at near disc power. I can easily do a nose wheelie, using brake power alone. The feel is so good, I can anti-lock brake the front. Apply, feel it start to slide, let loose and rebrake. The only thing I don't like and it is very minor, is the hood shape on the Cane Creek Road V-brake levers. There is far more clearance with panniers and I don't poke my calf anymore. Everyone here loves their cantilevers. They are prettier and match the aesthetic of Rivendell. I get that, but for me the superiority of V-brakes has become beautiful in itself. On Thursday, February 19, 2015 at 7:33:03 PM UTC-8, ted wrote: Deacon, The thing is, that definitely does not increase the leverage. The the vertical component of the tension in the straddle cable is equal to the tension in the brake cable (well half on each side). Lengthening the straddle cable reduces the tension in it as well as changing the angle at which it meets the brake arm. The vertical component of the tension stays the same, and the horizontal component is decreased. The net result is less torque around the brake post for a given force on the brake lever. For a wide profile brake like the 720, where the end of the arm is barely above the pivot, the decrease in leverage is relatively small. But it is a decrease, not an increase. To get an increase in leverage by lengthening the straddle cable the end of the brake arm would have to be below the pivot. Again I'm not claiming that the longer straddle cable didn't work better for you, just that the cause of the better can't have been increased leverage.

[RBW] Bikes and Recovering from shoulder surgery
Yesterday my new orthopedic surgeon informed me that I will have shoulder surgery in March. He suspects I have been walking around with a torn labrum in my left shoulder for some time (probably initially due to a bike wreck) but worsened the injury moving oak logs (for firewood) mid-fall. For those who know the jargon, it's a SLAP tear. Searching for info about cycling and recovery from this kind of surgery has left me a bit blue. It looks like 4-6 weeks in a sling, then very slow 4-6 months to full use. Ironically, I'd just received a 54cm Sam Hillborne frame the week I tore it. The frame is now fully built and sits unused. My questions are: Has anyone on the list had the surgery and, if so, what was your recovery like? And, what's the best wisdom from the group regarding cycling and recovery from SLAP repairs?

Re: [RBW] Re: Paul Brakes -- Wow!
Ted, Envision one half of a cantilever brake setup. There is an axis between the points where the straddle cable attaches and the brake pivots. We'll call this The Axis. Now envision a force vector along the straddle cable. If you conceptually break down that vector into components which are 1) perpendicular to The Axis and 2) parallel to The Axis, you will realize that any force parallel to The Axis will be working against the rigidity of the cantilever brake mount. So, you really want to maximize former vector component... that is, by applying the straddle cable's force perpendicular (90 degrees) to The Axis. Of course, you want to be maximizing this force vector as the brake pad is touching the rim. It's true that you can apply a great deal of tension to a straight cable by applying a force perpendicular to its axis. However, the theoretical infinite tension doesn't really affect braking when you consider the brake pivots (and the steel frame to which they attach) resisting most of that tension, which is what you would likely achieve with a high profile cantilever and shallow straddle cable angle.

Re: [RBW] Re: Paul Brakes -- Wow!
Oh... I forgot to mention that brake feel is more important than outright power anyway. Bikes have a small contact patch. It's important to know exactly when your tire is at max adhesion at maximum braking, and not past it. I bow out now...bye.

[RBW] Re: Bikes and Recovering from shoulder surgery
Jim, I suffered a labrum strain two years ago (not as substantial an injury) and kept reinjuring it due to my inability to *not* do things to put it at risk. One of those things was to continue biking on both a Bianchi with drops and a SOMA mtb with straight bars. I couldn't ride them without aggravating the injury probably setting back my recovery by months. Still needing to ride at least to commute to work, I bought a set of Bosco Bars and a shorter stem for the SOMA. That took a great deal of the pressure off my shoulders by shifting me to a very upright position. I didn't love being that high up but rode that way for about 4-5 months before putting the straight bars back on. Of course I felt safe putting the straight bars back on the SOMA because I had sold the Bianchi and bought a Hillborne with Albatross bars and haven't ridden the SOMA much since (https://www.flickr.com/photos/129545862@N03/15970729244/in/set-72157650518230279). I also haven't encountered any additional problems on the Hillborne. Now I am even looking to shift out the Albatross bars for the lower position of an Albastache. I feel pretty confident at this point that going a little lower won't re-injure the shoulder. I bought the longer Nitto stem so I can always raise the bars if it starts to hurt again. Good luck with a speedy recovery.

[RBW] Re: Bikes and Recovering from shoulder surgery
No idea on the details, but drink a big bowl of bone broth (or make it into soup) daily for a week or more before, and the months following. This helps speed the knitting and healing of bones and tendons and other stuff in there. To make your own, buy oxtail, put in a big soup pot filled with water, add two teaspoons of vinegar, bring to a boil, then simmer covered for 24 hours. As the broth gets low, repeat (or just always keep the pot on and near full during the day, adding a teaspoon of vinegar each day). Repeat until the bones are gone or the broth too thin, then keep using those bones but add another oxtail. Heal well!

[RBW] Re: Paul Brakes -- Wow!
Clayton- I too, have a love for non-canti's. Paul's MiniMotos make my heart sing. However I was set to go with Tektros (even after a bad experience with them years ago) and this thread made me rethink. I searched locally and found a cross racer moving to Vs on his CX bike and he offloaded his Neo/Touring setup to me at a price that was far more than fair. So now my resurrected SimpleOne will be sporting Neos up front and Touring in the rear. I personally feel that unless you are racing there's no reason not to go with Paul brakes. I've (almost) never heard a critique about their primary function (braking) in any of their multiple forms. Plus there's a wide variety to fit nearly any frame (including disc coming soon!). I'm not into being devoted to brands but when the pattern of quality is there...

Re: [RBW] Re: Paul Brakes -- Wow!
I too agree. Mechanical advantage is important to avoid having the lever bottom out before the brake fully engages, but pure power will be maximized when the straddle cable is 45 degrees to the arm. Hence the neo retros require a higher straddle cable than the touring cantis to maximize stopping power. Michael On Friday, February 20, 2015 at 5:25:28 PM UTC-5, Mark Reimer wrote: Deacon, I agree with you on this. Getting the straddle as close to 90 degrees has always been the position which yielded the greatest stopping power for me. With my neo-retro's (Aka the 'weaker' of the paul canti's) I have the cable long and up high, and I have enough power to lift up the back wheel if I really wanted. Lower straddle usually results in less power, and obviously less mud clearance as well. As I understand it, the idea is to get the cable as close to 90 degrees as you can WHEN the brakes are in contact with the rim. To read a much more exhaustive explanation than I'm willing to regurgitate, take a look at BQ's great write-up on setting up canti's. In the end, I'm sure we can all agree that Paul canti's are awesome.

I suspect you were told the opposite of what I am telling you, and that you understood what they were saying. Sadly they told you wrong. But happily they still steered you to something that worked for you. The phrase slushy brakes suggests to me low effort producing large brake lever travel with little braking effect. If that's what you had it was likely due to elasticity in the brake system, which is a separate thing from leverage. If you experience that sort of thing, look for what moves when you squeeze the lever hard after the pads hit the rim. For example, I found the steel front cable hangers flex a lot. Replacing mine with the aluminum ones improved the feel of my brakes significantly. Cables that change shape as the brakes are applied can be another source of excess travel.

But that point is mute now, as the Paul's are wonderful! I look forward to snow-free trails so I can try them out!

[RBW] FS: Joe Bell painted lugged frame - 62.5cm
Finally selling this oddball vintage classic quirky Joe bell painted lugged steel frame. Have had it for about 12 years, had lots of fun tinkering, changing, touring, etc... with it, but it's time to move on. If I recall correctly, the guy I bought it from sorta remembers the guy he got it from saying it was maybe perhaps a Claude Butler frame from the 70's. But what we do know is that on 5-26-87 Joe Bell finished splattering blue, red, green, and purple paint all over a yellow frame, and The Wanderer was born. It has a cool jet tube for routing the rear brake cable through the top tube, and a few nice other details. Vintage Shimano Deore XT canti brakes are included, as well as the headset and bottom bracket. Rear spacing has been set to 130. It's ready to build up and ride! Asking $250 plus shipping - make me an offer!
