Re: [RBW] Re: QB Bottom Bracket
Thanks, all. I have a new BB coming ... in the proper size. --Eric N Sent from my iPad2 On Jan 28, 2012, at 10:54 PM, grant grant...@gmail.com wrote: Either 107, 110, or 113 is fine. The 107 is close, but works. You'd think the 110 might be the way to go, but the Tange 107 and 110 have the same crank-side offset...so...hate to even bring this up because it's a dustmites-in-the-eyelashes kind of thing, but the 110, with the extra 3mm on the left, makes the Q more symmetrical. Three mm is soo tiny. Foot placement on pedal can make up for that x4, easily.

[RBW] Re: QB Bottom Bracket
I think mine came with a 107mm. If you're using the QB crank though, the 32t ring is going to be real close to the chainstay. real close. Hasn't been a problem for me though. -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

[RBW] Re: QB Bottom Bracket
My Quickbeam came with a 113 mm shimano BB UN-54 bottom bracket. This was not the first run but I can’t see that it would make a difference. With the Sugino Quickbeam crankset this gave a 48 mm chainline for the large ring ( i.e. the middle ring of an equivalent Sugino XD. ) I always rode in the large ring and never noticed that there was a problem. Only after a few years did I measure. I believe the shimano freewheel gives close to a 43 mm chainline on the Suzue rear hub. Even if you used a common 107 mm bottom bracket with the Quickbeam crank the large ring would still be outboard of the freewheel. I ended up transferring the 113 mm bottom bracket to another bike ( an atlantis that I am slowly building up as the snow slowly falls and my neighbour incessantly shovels his driveway), and I then used a 108 mm Phil Wood bottom Bracket with a Sugino RD crank, moved over a little which the Phil bottom bracket allows. This gives a better chainline. I think a 103 mm bottom bracket with a Sugino RD would be just about perfect. But once again, I never noticed a problem in the first place, the drivetrain was always nice and quiet. -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

I used a 107 Tangewith the Sugino crank and 39x36 ringsI use the White 16-19 on Formula hub and get near perfect alignment using 39x16 (66 ) or 36x19 (51). I can cross over the combos and get slight chain angle for 55 and 60 gearing. Using a single cog rear you'd have to pick which ring you want perfectly aligned and choose your BB width but I don't think its that important within reason.
