Information
Product details
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 7075-T6 aluminum (48-52 tooth rings are 6061-T6).
Specs
- Available in black anodized and raw (unpolished) silver
- 28 teeth to 52 teeth in 2 tooth increments
- Boost and non-Boost versions
- Standard/non-boost rings have a 3mm offset (inward)
- Boost rings are flat (so 3mm outward of our standard/non-boost rings)
- Standard/non-Boost rings can be flipped to give you 3mm more outward offset than our Boost rings
- This set up is is used on M30 cranks for a 55mm chainline needed for SRAM Transmission, Rohloff hubs, and Super Boost 157mm spaced hubs
