[RBW] Re: Question about Bleriot selling...drops or Albas more likely to sell?
I'd second this sentiment. You've done such a nice job building-up that bicycle, someone will benefit from it being complete. If you're in no panic to sell, just be patient. The BB might not be the first choice of RBW listers, but the outboard type is a perfectly good system and it certainly wouldn't put me off. If it ain't broke etc. IanA.

[RBW] More Biking to Work, per Census Data

That’s an almost 61 percent increase from the 488,000 who said they rode bikes to work in 2000. Of the 1.2 million workers in Chicago, 1 percent biked to work in 2012, a .4 percent increase since 2000. Those numbers are still dwarfed by the number of workers who drive or carpool to work. There were 140 million workers: 86.2 of them carpooled or drove alone to work. Only 0.6 percent biked and 2.6 percent walked. But the number of bikers is increasing. In 1980, only 0.5 percent biked to work. That dropped to 0.4 percent in 1990 and 2000. But now those numbers are increasing again, the Census Bureau says … -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

Two brief points: First, the only fork I've had break under me (yes, I was JRA; the bike was supposedly a NOS tandem) was steel. Fortunately, only bad bruising resulted.

Re: [RBW] another carbon failure
it's not a question of strength, the question is toughness - the ability to absorb strain energy over time without producing damage. Back to the cause and effect question. If you can demonstrate a low-energy or progressive fracture, you can argue that a break is a cause. With impact damage, you see high-energy fracture, that the part had absorbed everything it could and groaned to its limit before breaking.

Re: [RBW] another carbon failure
By strength I simply mean the general and overall capacity to withstand rigors of use over a long period; thus strength in this ordinary every day sense includes toughness. I don't think that anyone really questions that CF can be used in such a way to make things that in this sense are very strong indeed. My principal point was to distinguish the qualities of the material (including its inherent defects) from stupid use of it, in this context stupid light design. From what I read, much of the breakage is due to stupid light design and not to carbon fiber matrix materials as such. My own particular interest is, if bicycle parts are built out of CF matrix so used as to be sufficiently strong for the long term, how many of CF's advertised advantages over steel disappear. For example: will a CF fork designed to be as safe for users over the long term be hugely lighter than a steel fork of equivalent strength?

Re: [RBW] Re: What is the advantage of expensive hubs?
It has smaller ball bearings, but more of them, 13x 3/16ths bearings versus 9x 1/4 ths bearings. I don't view the aluminum axle as a liability. This bike will be ridden on road exclusively, and with 650b x 42 mm tires, so not exactly a harsh operating environment. I looked at the tech documents before making my selection. On paper the XT looks superior to my eyes. But I'll have a good point of comparison, I own one of the LX hubs also.

Re: [RBW] another carbon failure
I think that depends on what your idea of hugely lighter is. I think steel forks weigh about 1.5 lbs. and that reasonably strong carbon forks weighing half that can be produced. Perhaps cutting the weight of a part in half is huge, perhaps shaving less than a pound on a roughly 200 pound rider/bike combination is trivial. I believe that depends on ones personal view of the matter. Expanding it to include the whole frame and fork, a current Cervelo R5 frame and fork has an advertised weight under 2.5lbs. My AHH frame, fork, headset, and seat binder bolt came in a touch over 7 lbs on my kitchen scale. I am not aware of any great rash of failed Cervelos. I wouldn't refuse to ride a new Cervelo for fear of failure induced injury, and a lot of material could be added to a R5 before the weight advantage would be eliminated. The properties of a part are as dependent on its geometry as they are on its material, and the two tend to be interrelated. The early aluminum and carbon frames were built with frame tubes the same diameter as the steel frames of the time. They were widely considered to be very flexible, and were often derided as wet noodles. Carbon-fiber composite, titanium, and aluminum are all less stiff than cr-mo steel, but they are also less dense. Their lower density results in greater wall thickness for a given cross section and weight. Increasing a tube's cross-section increases its torsion and bending stiffness more than it increases the weight (for a given wall thickness). Reducing wall thickness too much makes a tube susceptible to denting and buckling. For a given tube diameter, a less dense material allows a lighter tube before wall strength becomes an issue. Klein and Cannondale found that by using dramatically larger tube diameters they could build lighter stiffer frames despite the fact that Al is less stiff than steel. Suddenly Al frames went from being comfy but soft and flexy wet noodles to being uber stiff and harsh, while remaining lighter than the steel frames of the time. In response makers of steel bikes introduced frames with oversized very thin walled tubes to try and stay competitive in the lightweight wars. But those frames were said to be very easily dented, they were viewed as fragile. Its generally a lot more complicated than just what material a thing is made out of. But if weight is really important to a person, they probably want a frame and fork made out of something other than steel.

I don't think that anyone really questions that CF can be used in such a way to make things that in this sense are very strong indeed. My principal point was to distinguish the qualities of the material (including its inherent defects) from stupid use of it, in this context stupid light design. From what I read, much of the breakage is due to stupid light design and not to carbon fiber matrix materials as such. My own particular interest is, if bicycle parts are built out of CF matrix so used as to be sufficiently strong for the long term, how many of CF's advertised advantages over steel disappear. For example: will a CF fork designed to be as safe for users over the long term be hugely lighter than a steel fork of equivalent strength?

[RBW] Re: Tire noise, way OT
I would expect your Prius tires to be lower rolling resistance, oriented toward fuel economy. On my Atlantis, I've run Schwalbe Marathon Supremes for years. The tread looks like Nike's swoosh and they are fairly noisy as slick-ish road tires go. A while back, I installed a pair of Soma C-lines and the noise is substantially less. The ride is also a lot better. Less aggressive tread and more flexible sidewalls give a quieter, smoother ride. Not sure that I detect any difference in rolling resistance but a more sensitive rider or some instrumentation may be able to answer that. dougP On Friday, May 9, 2014 7:43:29 AM UTC-7, Michael Hechmer wrote: I have noticed that some bike tires are noticeably noisier than others.

If you include the rubber in your definition of casing.

Similarly tread compound has been shown to have an impact. Tires with light casings tend to have light treads, and vice versa.

Has anybody tested say the BG Rock n' Road and a tire built with the same casing but a tread more like what the new Compass tires have? It is very hard for me to believe that a thicker heavier layer of tread doesn't increase the rolling resistance of a tire.

He had not adjusted the bearings from the Shimano factory before having this failure. *I personally think that this is a silly place to save weight on a touring bike and would recommend LX hubs over XT ones for touring and commuting wheelsets. *Since the end cap is also used to preload the bearings it will not be fully threaded onto the axle. *In this case it looks like it was being held on with only two or three threads. I was disappointed to see this development. *XT has almost always been light in smart ways, so that it ends up a little lighter than LX without giving up any durability. *Now it looks like LX is the durable group and My heavy duty city/tour wheelset is built on plain Deores. The bearing feel is phenomenal compared to even five years ago. The seals are magnificent. They just need a little touch of the cone wrench out of the box.

We didn't test the Jack Browns, but we did test the Nifty-Swifty and Maxy-Fasty, which are the same tires, only in 650B. The Nifty-Swifty was about 3% slower. However, compared to other tires, both were among the slower tires we tested, indicating that the casing has a much greater influence on the speed than the tread thickness and extra puncture-proof layer... at least for tires with a relatively stiff casing. On a supple tire, the puncture-proof layer might slow you down more, simply because it defeats the supple casing. If the casing is already stiff, then adding a stiff layer might not do as much.

[RBW] Re: Heron: Why the incorrect info about tire clearance?
I designed the bike for those clearances, and the samples we got fit those tires. But -- you know---I don't want to get into a backand forth, but would just like to make a few points - one maker's 700x35 is skinnier or fatter than another's at least a few (that I know of) makers started being more accurate with tire dimensions around about 2003. Panaracer changed its 35 to a 32 around that time, and I think others followed - it's a stretch to say I've made a living being honest about bikes but it's not a stretch to say I've always gone to obsessive extents to be forthright, and yet...this - what one designs and requests is sometimes different from what one GETS. in my experience, there is less variance from spec from higher volume makers than from lower volume ones. I don't mean to paint smallies with a broad brush, but foundationally, if you're going to make a hundred of the same thing at the same time, it ultra-behooves you to lock in the machinery within a gnat's hair of spec. We have, over the years and in secret and at our own expense much of the time, rejected frames because this or that tiny detail wasn't quite exact. Because we see so many bikes, we have keen eyes and senses for out-of-spec, and we don't get on the slippery slope of accepting it this time for political or diplomatic reasons. These are hand-made bikes, and although Jim may not trust us anymore (I understand that), i believe in my bones that they are remarkably consistent and true to the propaganda about them. It's what I do with my life, and I care deeply about all those details. But with tire designation changes and the rare mfr goofup and the nature of human labor, it is just hard to achieve 100 percent perfection. I WISH that didn't call into question our standards or intent or integrity, but I certainly understand Jim's disappointment, and am sorry for it.

Re: [RBW] Re: What is the advantage of expensive hubs?
real usage data is the best way to compare durability for these hubs. The XT has had a lot more axle breakage reports since the switch to aluminum. Yes it is a larger diameter axle to compensate for the much lower yield strength, but the incidental data I've seen ( mostly MTB related) shows a much higher failure rate. Larger ball sizes increase lifespan as well BTW Considering your weight the heavier LX hubs would most likely be more durable. ~mike -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

Re: [RBW] Re: Tire noise, way OT
This is interesting and jibes (not jives) with my own admittedly limited experience, particularly with Schwalbe Kojaks and Big Apples. Both of these roll very surprisingly well given their puncture resistance and their puncture belts, but not quite as well as the unprotected Parigi Roubaix or skinnier racing tires. Recently I have been alternating between the Ram, with the 622 X 30 mm P-Rs, and the Curt with 559 X 32 mm Kojaks, and trying to mentally clarify exactly what the difference is. At this point it is no more than the sense that the Ram (over the same routes with similar loads in similar conditions in roughly the same gear, with roughly the same riding position) just feels slightly more crisp and light while the Curt feels as if, somehow, there is (and this is entirely metaphorical) a sort of veil or fog over the ride. Note though that I have also felt occasionally that the Curt feels faster than the Ram because of its slightly lower weight and its fixed drivetrain; or rather, there have been times when the Ram somehow felt more sluggish. But generally the other distinction predominates.

[RBW] Re: Tire noise, way OT
Jan, Most things are relative, and the law of diminishing returns tends to apply. Surely there are hysteresis losses in the flexing of tread material as it moves into and out of the contact patch, and also losses due to the casing. Their relative significance for a specific tire may be difficult to measure. Rubber tends to have a high damping coefficient (hence its frequent use in isolators) but on a performance oriented tire there usually isn't a whole lot of rubber there. I don't know how to decide what sort of increase in tread rubber would make sense to compare to adding a layer of kevlar to the casing, but without measuring the speed of tires with the same casing and varying treads I think declaring tread less significant than casing from a design standpoint is premature. If anybody ever put a latex filled tread (like some stout schwalbe tires use) on a light supple casing, Ill bet they would get a very slow tire. From a buyers standpoint, there may more variation in the casing construction of various performance tires than there is in their treads. If thats the case then, when buying tires, casing may be more important just because thats what is different. Do you know of folks measuring the suppleness and hysteresis characteristics of tire casing material? How is suppleness quantified? thnks Ted On Friday, May 9, 2014 2:04:49 PM UTC-7, Jan Heine wrote: We didn't test the Jack Browns, but we did test the Nifty-Swifty and Maxy-Fasty, which are the same tires, only in 650B. The Nifty-Swifty was about 3% slower. However, compared to other tires, both were among the slower tires we tested, indicating that the casing has a much greater influence on the speed than the tread thickness and extra puncture-proof layer... at least for tires with a relatively stiff casing. On a supple tire, the puncture-proof layer might slow you down more, simply because it defeats the supple casing. If the casing is already stiff, then adding a stiff layer might not do as much.

I am fairly sure research has shown that slick tires have less rolling resistance than tires with a modest tread (I can't speak to the size of the difference though). Similarly tread compound has been shown to have an impact. Tires with light casings tend to have light treads, and vice versa. Jan may have tested Jack Brown tires in both Blue and Green variants thereby measuring the effect of the casing reinforcement (as I am not a BQ subscriber I don't know). Has anybody tested say the BG Rock n' Road and a tire built with the same casing but a tread more like what the new Compass tires have? It is very hard for me to believe that a thicker heavier layer of tread doesn't increase the rolling resistance of a tire. I am skeptical about the notion of a solid center ridge making a thick tread fast. I haven't much idea if that relates to noise levels at all.

You can create sound without all that much energy loss, and part of it may be related to the audiological perception of the difference - there's a fair bit of tone/timbre difference which certainly fades and we also probably get used to over time. But, I'm not sure you find much actual friction effect - the deformation of the casing and the ease with which that occurs has greater impact (if I'm understanding Jan's tests and writings, for example). - Jim -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

[RBW] UPDATE! Head-Badge Poster! Now in Hi-Res
Glad I waited to post the HiRes version. A fellow bunch member and former RIv crew member was able to provide the elusive missing link - the first ever Rivendell head badge! It's now in it's rightful place of honor at the top left corner. Here's the link to the file on Flickr - you can select the size of the file. The original is 24 x 30 so be prepared for a long download. This has been fun, but I'm burned out on badges for a while.

[RBW] Compass Barlow Pass tires
A pair of these tires have found their way onto my Sam Hillborne. Realize they will stretch some, but at first glance, they looked a lot skinnier than the Baby Big Bens that were on the bike. Due to recent bad weather, only was able to get about 9 miles in on the tires today. My first impressions are - WOW. I like. Seemed to me the ride went faster than usual. My time was definitely quicker than my average this year. Thre ride is also very smooth. Am very much a convert to these tires. Yes, some of this is probably due to wanting the tires to work well. Still and all, am hoping to keep these on the bike this year and just enjoy the ride.

[RBW] Just when I think enough is enough on bikes... Japan
Jan Heine comes along and posts his observations on his Japan travels. God bless him, we are not going to shoot the messenger here, but the upshot is the Japanese are serious randonneurs, city bikers, racers and all kinds of things. They are making and have been making some really fine bicycles with distinctive innovations and deviations from what we think of as the norm here. They are certainly no slaves to using a particular manufacturer's group These are not your father's Nishikis. I started looking at some of the bicycle builders mentioned in Jan's articles (Hirose, Toei, Grand Bois, ...) and was stunned. One of the best examples is here at General Workshttp://www.generalworks.com/toeisha/photo/photo_t5001_eg.html . Seriously. Custom rear derailleur braise ons. Custom front dérailleur braise ons. Hub area rack. Internal cables. Tire (actually rim) friction dynamo that looks like it might work. Braised on rear lamp mounting. Much more. I am going to extend my next Japan business trip to doing some bicycle shop visitations and hopefully make some time to ride with people there and hear what they think.
