The crankset with its 32T chainring, plus a BSA 73mm threaded bottom bracket.

Compatibility & fit

This is the non-Boost version with a 50mm chainline. The included bottom bracket suits frames with a BSA (English-threaded) 73mm shell. Prowheel also offers this crank with a BB92 press-fit set, which is not included. Prowheel rates the CHARM-FD099A-TT 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.
