Compatibility & fit

This is the non-Boost version with a 50mm chainline. Fits a JIS square-taper bottom bracket; Prowheel specifies a 113mm spindle. No bottom bracket is included. Prowheel rates this crank for 9, 10 and 11-speed drivetrains. Fitting is a separate workshop service and isn't included. Our Marrickville workshop can fit the crankset and bottom bracket and check your chainline.
