RE: [RBW] Bleriot vs. Quickbeam efficiency
The Bleriot has slightly slacker angles than the QB--can you compare your saddle setback? It's amazing what a difference in perceived effort a cm or so of saddle setback can make...check it by dropping a plumb bob (I use a washer on a piece of cotton string) from the nose of your saddle past the bottom bracket and measuring from the string to the center of your crankarm bolt. Steve -Original Message- From: rbw-owners-bunch@googlegroups.com [mailto:rbw-owners-bu...@googlegroups.com]on Behalf Of Tyler Sent: Thursday, May 20, 2010 6:13 PM To: RBW Owners Bunch Subject: [RBW] Bleriot vs. Quickbeam efficiency I've had my bleriot for 2 years and my quickbeam for 1 year. I bought the quickbeam to essentially be a simpler, single-speed version of my bleriot. Since then the quickbeam has become my preferred bike. I find that I'm (empirically) more efficient on my quickbeam and don't tire as easily. After a 50 mile ride on the bleriot I feel tired; after the same ride on the quickbeam I feel fine. I don't ride with a computer on either of my bikes, the only constant being my cycling partner. I find when I'm on my bleriot that I'm regularly slower than her but when I'm on my quickbeam I'm regularly faster. I'm at the point where I only ride the bleriot if there are going to be hills that I can't tackle on my quickbeam. "Being slow" doesn't bother me as much as the perceived difference in efficiency. The bleriot feels like it's dragging some extra weight regardless of the gear that I'm in while the quickbeam feels like it wants to keep rolling. If the bleriot felt similarly effortless I wouldn't be bothered if it was actually slower than the quickbeam. I wish that I had a way to definitively gauge this "dragging" feeling. The bikes are setup very similarly: Quickbeam: 60cm frame, 700 x 32 paselas, 32h stock wheels, sugino crank with 40/32 x 16/19 gearing, noodle bars, brooks saddle, MKS touring pedals without clips/straps Bleriot: 61cm frame, 650b x 42 grand bois hetres, 36h lesnik-built wheels, sugino crank with 48/38/26 x 11-30 gearing, noodle bars, brooks saddle, MKS grip king pedals Sometimes I wonder if the hetres are just "slow" but that seems to go counter to the ride reports of dozens of people who ride with hetres and claim they're quite fast. I thought about swapping to cypres tires (650b x 31) but that's a $120 investment I'm not ready to drop.. especially given that I've read you won't tell much of a difference between hetres and cypres on paved roads. The quickbeam is the first single speed bike that I've owned. Is it common to find that a single speed bike is noticeably more efficient for its 1 gear relative to a multi-speed bicycle in a gear of the same gain ratio ? Can any other quickbeam owners tell me about the perceived efficiency difference between their quickbeam and their geared road bike(s)? -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

I have a different opinion here - the cypres is lighter than the hetre, and at higher pressures, it behaves more like a "fast" road tire than the Hetre in my experience. again, it's more noticeable when the road goes up or when I want to accelerate/push hard. that said - yeah, you might notice much of a difference between the two if you aren't riding somewhat aggressively. > The quickbeam is the first single speed bike that I've owned.

[RBW] Re: Bleriot vs. Quickbeam efficiency
I've experienced the same thing-- though my single speed bike is not a Quickbeam. I have always explained it to myself like this: My one gear is much easier to pedal than many of the gears of the multi-geared. This means that on downhill or flat sections I am not working as hard as I would be on my geared bike and am probably spinning more efficiently (higher cadence). When I get to the hills I have much more energy than I would on the geared bike and am able to go up it much faster-- then it is back to the downhill. and Repeat. It is the speed on the hills that makes the bike feel faster. I find that I am as fast/ feel faster on the single speed up to about 50 miles or so. The geared bike also feels faster on big climbs-- there is a classic 20+ mile climb here that is neither fast nor fun on the single. The numbers on the bikes' computers verify this. As an experiment, try putting the Bleriot in a comparable gear as the single and don't shift. Still notice the difference? Lastly, any chance there is a small engine in the seat tube of the Quickbeam? Might be worth checking.

[RBW] Re: New-to-me Quickbeam frame/fork pics
Thanks, Jeremy. I saw an old thread involving Sheldon in which he said: "White Industries singlespeed hubs are intended for about a 47.5 mm chainline with a singlespeed freewheel or typical fixed sprocket. The double sprocket pretty much splits the difference, giving chainlines of about 45 & 50." I'm wondering if this is so in regards to the Riv Suzue free/free hub.

Re: [RBW] Bleriot vs. Quickbeam efficiency
Tyler - I also own a QB and a Bleriot. I don't notice a big difference in the effort expanded, but that's more likely due to how I ride each bike. I use the Bleriot primarily for commuting with a modest load on the rear rack. I also fit it with Albatross bars. I use the QB for "fun" rides. I must concur with several of the other posters. The QB is a lot of fun to ride, and it is the one bike I ride most. I am not technically proficient enough to weigh in on the tire, psi, or geo, although I tend to agree with what most have written. I actually enjoy climbing, and I use the QB a lot to do that here in NorCal. Aside from the obvious advantage more lower gears might provide, the QB is geared low enough that I can huff and puff my way up nearly everything I assault. I'm not too proud to get off and walk, either. Because I am geared so low on the QB, I am always reluctant to ride it when joining other riders who have derailers. On flats and descents, they leave me in the dust. I most enjoy the QB when riding solo, which is most of the time. I have two crank sets for the QB, as well as two wheel sets. For hilly/mountainous riding with some trail work, I use a 28/36 chain wheel combo with 17 freewheel on the drive side, and a 22 free on the flip side for the steepest climbs. For normal road riding here in the Bay area, still lots of climbing, I use the stock chain wheels and a White 16/18 free and a 20 free on the flip. I almost never use anything but the 32/40 x 18 combo. A couple of the others remarked about just picking a moderate gear on the Bleriot and ride it without pulling a shift. I recommend that. That is how I discovered the fun of single-speed to begin with. I was on a long ride on my Romulus, but very pre-occupied. A goodly distance into the ride it occurred to me that I had not been changing gears at all. I finished that ride without shifting, then took a dozen more that way before committing to buying the QB. I have never regretted it.

[RBW] Re: New-to-me Quickbeam frame/fork pics
The 47.5mm hub chainline is specific to White Industries hubs (i've got one of those too!). Most normal "track" hubs (including the Suzue, the double-free QB one was based off of their track hub) are nominally a 42mm chainline. But, if you just take sheldon's numbers for the DOS on a white hub and minus 5.5 mm (47.5-42), you should get the chainlines of a DOS on a 42mm hub- so 39.5mm and 44.5mm. Approximately. Welcome to the single-speed club--calculating chainline is one of our initiation rites. This article is about fixed gear set-up but can be equally applied to SS rigs, it has some good stuff including a how to measure chainline on the bike: http://63xc.com/mattc/setup2.htm On May 21, 11:04 am, Lee wrote: > Thanks, Jeremy.

[RBW] WTT: 175mm XD2 crank arms for 172.5mm arms
Hi all, I have a pair of 175mm Sugino XD2 crank arms that I am looking to trade for a pair of 172.5mm XD2 arms. I would like to trade just the arms, and not the rings. They are in good but used condition, and have the little crown logo. Thanks, Steve -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

[RBW] Re: Mixing Campy 10 and Shimano 9 - Zinn article?
I use the Jtek Shiftmate to combine Campy 10sp shifters with ShimaNo 9sp cassette. It works flawlessly and is cheap. You won't be disappointed.

[RBW] Re: New-to-me Quickbeam frame/fork pics
Jeremy, thanks so much. That's really helpful. And you're right, you should have seen me last night, a couple of empty beer bottles, quad- ruled paper, a million (one million!) tabs opened up in my browser going over crank, hub, cog combinations, etc. It all seems so simple on my Schwinn single-speeds, what with the one-piece crank and all. Your DOS calculation seems right on, as 42mm would put the chainline right between the cogs. I plan on running fixed on the other side, but I bet that the fixed cog will work out to 42mm obviously. Now I just have to find a suitable crank and chainwheel setup, as I don't have the original QB crankset, and I'd rather run a single chainring (for now), with lower Q-factor if possible/affordable.

[RBW] Re: Bleriot vs. Quickbeam efficiency
Thanks for the input everyone! * I've checked the whole bike for "drag" except the wheel bearings, I'll give those a look. * I need to confirm that my body position is the same between bikes. I tried to set them up as close as I could but it's possible one or both configurations have drifted from the original setup after dozens of tweaks over the last year. I particularly need to look at saddle setback given that the bikes have different seat tube angles. * The bleriot probably weighs a few pounds more than the quickbeam, though given my own weight I don't think that would make much of a difference. Even if the weight difference was 5 lbs, that would still only be about a 2% difference in total weight. The efficiency difference between the 2 bikes feels well over 2% to me. * I ride with the hetres as high as 60/65 psi, usually closer to 50/55. Yesterday I dropped them to 45/52 (based on my guesstimate of 15% tire drop from the chart in VBQ) and noticed a pretty substantial difference (mostly improvement). Today I did some hill climbing on the way to work. I found myself exhausted like I was fighting against both the bike and gravity. The tires feel squishy to me when I'm standing which might be why climbing while standing and accelerating from a stop feel "inefficient." Aside from the hill climbing this morning, I've been riding the bleriot in the same gear that I use on the quickbeam for around town riding. The bleriot still feels more difficult in this gear but I need more time in the saddle to really confirm that. * The quickbeam uses 32mm paselas with tourguard which I don't consider to be racing tires, so I don't think it's a completely unfair comparison to the hetres. The paselas feel like the perfect combo of comfort and speed for me, I don't get that squishy feeling when I stand (which I frequently find myself doing on the quickbeam) but the tires are plenty comfortable even for long distance riding. If panaracer made 650b x 32 paselas I'd buy a pair in an instant. Maybe I just need to take the plunge on a pair of cypres since they're probably the closest I'll find to paselas for 650b. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Re: [RBW] Mixing Campy 10 and Shimano 9 - Zinn article?
I have tried several ways to mix Campy and Shimano. This is what I've learned: 1. Third party cassettes suck, stick with the S & C brands. 2. If you keep the same number of gears, the Shift-mate gizmo work very well. 3. Sram chains seem to work very well with both Shimano & Campy. 4. You can rebuild Campy Ergopower levers to 9 or 10 speed (pre 11sp stuff). Cheers!

[RBW] Re: Mixing Campy 10 and Shimano 9 - Zinn article?
I'm not sure what you mean by keeping the same number of gears. Are you implying that mixing 10sp shifters with a 9sp cassette is less than ideal? If so, I can assure you that I have that setup on two bikes and it works flawlessly. Perhaps other people's experience differs depending on the precise combination of rear derailleurs and shifters. For what it's worth, on both bikes I have Campy Veloce 10sp shifters, Ultegra long cage rear derailleur, and an Ultegra 12-27 9sp cassette. Zero problems with this setup. The Jtek works great in my experience. On May 21, 5:23 pm, James Valiensi wrote: > I have tried several ways to mix Campy and Shimano. > This is what I've learned: > 1.

Re: [RBW] Re: Mixing Campy 10 and Shimano 9 - Zinn article?
Aaron, I used the Jtek for 10speed mix ups, with great success. I didn't know they made one to mix up speeds as well; no doubt it works as well. There was one other method I tried: using Campy 10 speed shifters with Shimano 9 speed cassettes and deraileurs, where all you do is route the rear cable differently. This worked OK. Cheers!

[RBW] Re: Bleriot vs. Quickbeam efficiency
I've known about the Soma New Xpress for awhile but assumed it won't be a good choice for me, especially since it's described as being somewhere between the hetre and the col de la vie in "speed." I stopped by Box Dog Bikes on the way home to pick up a pair of Cypres's. I mounted them and took the bleriot for a spin around the neighborhood. Even on the short ride I noticed a significant difference; much less of that sluggish feeling and almost no hesitation when pedaling out of the saddle. This is promising. I also liked the fact that I can remove and reinstall both wheels without having to deflate the tire. Tomorrow I'll take the bike up some hills to see if that's improved as well. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Small drag differences can be big after a while. Freehub lagging (look for slack n the chain when you coast), wheels not completely seated in the dropouts, binding in the hubs when you clamp the wheels down. And, of course, the classic brake pad rubbing. > * I need to confirm that my body position is the same between bikes. > I tried to set them up as close as I could but it's possible one or > both configurations have drifted from the original setup after dozens > of tweaks over the last year.

My comparison is between the Quickbeam and the Hilsen, which are probably closer - especially since I tend to run the same tires on each. I definitely notice a difference when I switch between them, but I've usually got the QB in fixed-gear mode, so for me, I think it's more of a difference of fixed versus coastable. However, it took about a year of subtle tweaking to make the setups match. The final step was swapping to a slightly shorter stem on the Hilsen. (And by "match" I really mean reasonably similar - they don't match, the bag/rack arrangements are different, I have different saddles on them, etc.) One thing that I notice is that after I've been riding the QB for a while, switching to a coastable, many-geared bike just beats me up. My legs are sore and I'm more tired. It may be because unlike the Quickbeam, the cadence is not tied to the terrain. The other thing I notice is that the Hilsen feels less efficient for maybe a ride or two, and then it seems normal. By the third ride in a row, I'm riding the bicycle a bit more efficiently - using the gearing differently and feeling more fluid on the bike. You may want to play with riding the Bleriot for a few days straight, and see what you learn. It doesn seem to me that different models have different personalities, and sometimes you have to find the way it likes to be ridden. hope that's of some help, - Jim -- Jim Edgar cyclofi...@earthlink.net Cyclofiend Bicycle Photo Galleries - http://www.cyclofiend.com Current Classics - Cross Bikes Singlespeed - Working Bikes Gallery updates now appear here - http://cyclofiend.blogspot.com "Steel's what you want for a messenger bike.
