Direct-mount ring

The chainring bolts straight to the crank without a spider, and Prowheel makes it interchangeable, with 32T to 38T rings listed for this crank.

What you get

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

Compatibility & fit

Prowheel lists this -B version as Boost 148 compatible. 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 DMB-CR098A-TT for 11 and 12-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.
