White Industries MR30 TSR 1x Chainring

TSR (Tall-Short-Ring) 1X chainrings are designed to work with 8-12 speed 1X drivetrain systems.  The tall/short tooth profile helps prevent the chain from falling off the ring when riding through rough terrain and is a must on 1x drivetrains, but is also compatible with singlespeed drivetrains. Made in our shop from 7075-T6 aluminum (48-52 tooth rings are 6061-T6).

Specifications
