What size Bottom bracket for Soma Rush?
So i finally got up the balls to lay down some cash and bought a new Soma Rush size 53. I'm switching over from an old 126 spaced conversion and I know I'm probably going to need a new bottom bracket. Anyone know what size bottom bracket I'm going to need for the Rush or does it depend on what crank I'm using? Thanks for the help. Cheers.

it's a 68mm english threaded bb shell. the length of the bb depends upon your crank, and desired chainline.

the 109 part may or may not be wrong.
totally dependent on his crankset
for all you know he's using a Miche, then you'd be off with both the length *and* the taper.

yes, the darned miche set up, i am still trying to get my chainline right with the soma frame, and miche bottom bracket and cranks. kind of a hassle, but i will be building my miche hubs up to new rims in a bit. maybe with dishing the wheel and really setting my cranks right i will get it down. if that is what you are using, i am sorry, cause it kinda sucks getting it right.
