Information
TSR (Tall-Short-Ring) 1X chainrings are designed to work with all modern 10/11/12 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 U.S. sourced 7075-T6 aluminum (48-52 tooth rings are 6061-T6).
