I have a pair of Race Face Turbines I bought about 10 years ago, they are 9spd compact drive with ISIS BB. I haven't used them in years and no longer have an ISIS BB, however I want to fit them to my girlfriends reasoanbly modern Diamond back which is currently fitted with Truvativ square taper cranks which weigh a ton.
How do I go about sussing out what axle length BB I need?
Thanks!
