Hi everyone,

I'm building my first touring bike from an old Schwinn Sprint frame (ChrMo steel, old road frame). While the frame fits me perfectly, the current components won't do for a touring bike (it's used as my single speed commuter right now).

I'm handbuilding my wheels with Mavic A719 rims and Shimano 105 hubs. The frame hub spacing is 125mm, so the 130mm hub should fit.

Other components I've selected can be found in the attached picture. Will this all be compatible? What other measurements do I need to take on my frame to make sure this all fits?

As you can see, I've decided to go with a 9 speed drivetrain. I've decided on a 11-34t in the back with a 48-26t in the front, would this work for 2-3 week long tours (self-contained, so medium-heavy load)? Anything from flat to relatively hilly terrain. Using Sheldon Brown's calculator that'll give me gear inches from 116.8-20.5 w/ a 175mm crank arm, which seems pretty good. I realize that the 116.8" is a little speedy, but I'd love to use it as my commuter outside of trips, at least for a little while.

I've been having a hard time finding a crank set that will fit a tapered square bottom bracket. It seems that this would be easier to maintain/fix in the field. Any recommendations? Also, are there different sizes of bottom brackets, or is it one-size-fits-all? What do I measure for that?

Any feedback would be much appreciated!!
