ISIS BB size for FSA crank

[Jay Torborg]

I just bought an FSA compact crank on ebay and I'm trying to figure out what size bottom bracket to get. I think the BB I'm currently using on my Ottrott is 102mm english thread, but the FSA ISIS bottom brackets don't come in this size. Is 68x108mm the size I'm looking for?

Thanks for the help.

Jay, FSA's Ultimax series goes down to 103. To my knowledge the FSA BBs are the only ones that are cold forged. A few of the other brands have adjustable chainlines.

FSA Carbon Pro Compact Drive 50/34 + FSA Platinum Pro Ti BB 68x108 + Ottrott yields a good chain line. The BB has been very good, also have it on mtb x 2 years without trouble. Goes together well. FSA seem to adhere to the standards well. Standard double FD has worked well, Record and Ultegra that I have tried.
