ISIS equivalent for Shimano BB-UN52
I have Ritchey WCS MTB crankset laying around that I'd like to install on my Bridgestone XO-4. The original BB on this bike is a Shimano BB-UN52 68x107 with an Alvio triple crankset.
The WCS crankset takes an ISIS BB, so would anyone know what the equivalent ISIS size would be?
