    New question here. What size BB to use with Raceface Evolve cranks?

    I just bought a used Raceface Evolve crankset,without the bottom bracket. I heard somewhere that Raceface called for a 108mm bottom bracket length for this crankset,but I'm not sure.It seems odd,because most ISIS I've seen,including RF,were 113's...Does anyone know if I can use a 113 instead,or will it mess up my chainline too much..The only 108's I have seen were RF SRX,which I think are crappy...FSA sells 68x108's,but I can't find a 73x108 listed...I've tried contacting RF directly,but with no success...Any ideas? Thanks all...Happy Trails!..............John

    Here is a link showing the BB for a few diffferent RF cranks. I have a 113 mm BB on my RF Ride XC too.

    There is no added value to my participation - in fact, just more confusion.
