Sized for young riders

Prowheel makes the junior DMJ-CR093A-TT from 127mm to 160mm with 24T to 34T rings, so smaller riders get a modern 1x crank that fits them.

What you get

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

Compatibility & fit

This is the standard (non-Boost) version with a 49mm 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 it for 10, 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.

Covered against manufacturing defects under Prowheel's warranty. Normal wear, crash damage and incorrect fitting are not manufacturing defects. For warranty support, return the product to Tune Cycles and we'll manage the claim with KWT Imports, Prowheel's Australian distributor.
