Is there ever not a headwind? The Camino Alto climb is the last little hill - as VN likes to write, "the penultimate climb" and it just cracked me. Calorie bonk, feeling nauseous, no power and more importantly, no Goal. The bit out of Sausalito is always close enough to the finish that I can put up with it.

Re: [RBW] Re: QB drivetrain questions
The original deraileurs shifted 1/8" chain, if I remember correctly what I read in The Dancing Chain. You need more space between cogs, of course.

Re: [RBW] Re: QB drivetrain questions
The only thing I'll add is that 1/8" can run a little noisily on a 3/32" setup. There's a little more noise in a QB drivetrain because the chainline is not absolutely straight - thank goodness for a lot of rock 'n roll concerts in my youth, so it doesn't really bother me... It's minimal though. I think... - J "clanking, what clanking?"

[RBW] Re: QB drivetrain questions
I think the way things are now, if you're running a single cog setup with a good chainline, 1/8" and 3/32" are pretty much interchangeable. I prefer running 3/32" because your options for chainrings are much wider- it's hard to find 1/8" chainrings that aren't BMX (i.e. spiderless) or track (usually 144bcd and in the 46-52 range) specific. That being said, you can run a 3/32" chainring with 1/8" chain and cog with no real issues- i've never experienced that set up wearing faster or any differently. I like having things matchy-matchy so if I'm starting from scratch i like to have all 3/32" stuff. On the other hand, if you've got a setup like the stock QB where the chain will be out of line some of the time (or even a plain old flip- flop, often times there's a slight difference in chainline between the fixed cog and freewheel), 3/32" is better because is more laterally flexible and will handle the displacement with less noise and risk of derailment. 1/8" can handle it (early derailers, like pre-5 spd, used 1/8" chains), but it's not what it's made for so it'll be more finicky. I'll leave the bushing vs. bushingless debate to people like sheldon (rip), peter w., and jobst.

[RBW] Re: QB drivetrain questions
I'm surprised that Harris recommended the 1/8" chain considering Sheldon's advice ... http://www.sheldonbrown.com/fixeda.html#chain If you look on Peter White's site he recommends the 1/8" chain because it has bushings. I can't find it now, but I'm pretty sure I read where Sheldon had recommended against 1/8" BECAUSE of the bushings. http://www.peterwhitecycles.com/fixed.asp (search on "Izumi Track Chains 1-1/8") Mr. White had additional information about Cranks. On the same page he says (my paraphrasing) - track cranks, bb, chainrings, etc. are built to a higher standard than those intended for derailleur bicycles. He sells many Sugino cranks on that page but doesn't include the XD2. Is the XD2 with (I'm guessing) standard road chainrings a compromise in any way? I guess these are just theoretical questions since I'm quite happy with the stock configuration. On Jan 29, 12:07 pm, Mike wrote: > Oops.

[RBW] Re: QB drivetrain questions
I don't think you'll have any problems using a 1/8" chain.As for chain length, it depends on your gearing, but if you're going to use an 18t cog you'll want to select chain-length to run the axle much farther toward the front of the dropout when on the 40 tooth ring. Dropping to the 32t ring will move the axle back about 1" (each tooth you drop changes the backend length by about .125" give-or-take).

[RBW] Re: QB drivetrain questions
1/8" chain is ok, but it's better to use 3/32" dérailleur chain if your rings and freewheel will accept it. If the rings and freewheel/ cog are 3/32, the 1/8 chain will fit somewhat sloppily, which will cause more wear (I think). Since the standard QB drivetrain uses two chainrings, it makes sense to use 3/32 chain because it's more forgiving of imperfect chainline. But if you already have 1/8" parts, use them, but if you're starting from scratch, 3/32 is better. On Jan 29, 10:29 am, Mike wrote: > So I scored a QB frame and will be assembling it soon.
