Hi all,

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.

Thanks!

what size did you have on there?

sizes are 108, 113, 118. you dont want the 118 so depending on what you have and your judgment you can go with either of the two other sizes

It was an 118 with the triple.

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?

Thanks

I installed the 108 based on Soil Sampler's answer and from asking around at the LBS. Seems to have been the correct choice.
