My friends got me a FSA Omega compact double for my birthday (I live in a hilly area, and 39-26 can overcook my cardio), and of course, I wouldn't mind swapping the Ultegra 6500 crankset off my Cannondale R2000 '99 vintage.
Question is, the chainline on my bike right now looks great. It's maybe about 1 mm off from the front to back (using the accurate method outlined by Zinn and Road Bike maintenance using a decent caliper). But wouldn't using an external BB crank severely affect the chainline? Or am I missing something obvious?
Also, if anyone can confirm that the R2000's BB shell is 68mm wide would be great. I can't measure it until I take the cranks off and I'm hoping someone would know so I don't have to
