quick question about replacing my BB
hey. i have a generic aluminum frame that i got from the trash pile. i know it's generic judging by the crap components. also, whoever it belonged to ripped all of the stickers off, so i can't identify it. the only stickers that remained were a "7005 hand built aluminum" one on the seat tube, and a "made in china" one on the top of the BB. anyway, it had an adjustable BB (the kind with the fixed cup on the drive side) that i removed, and i'd like to put a race face evolve xc crankset. i was wondering if i could install an external BB like the race face x-type. the bottom bracket is 68mm, but i'm not sure if the threads or the diameter would be the same. i read sheldon brown, but i want to double check!
