I'm in the process of converting my Klein Reve X triple to a compact double. I have an ISIS drive FSA Carbon Pro Compact Crankset and have to change out the bottom bracket. I know I need a 68 english, but how do I figure out which spindle length to buy which this crank? Any help/info would be greatly appreciated.
I too have the FSA carbon pro compact crankset. I got it used and I'm putting it on a new frame. So I'll go with your answer of 108mm on spindle length (68mm BB). But I am particularly interested in how you know or how I could tell if I didn't have Bike Forums?
