Details

UL Chainrings are the lightest 1x XC/Gravel chainrings on the market. Using the SL Chainring as the platform, we tweaked the arm design and strategically machined the chainring so that only minimal sacrifice was made in impact strength for large gains in weight reduction.

- Direct Mount chainring for XCX, TRS, and LG1 cranks
- Updated M3 narrow-wide tooth profile eliminates chain noise, and decreases overall system wear while retaining chain
- 10/11/12 speed. Compatible with both Shimano and SRAM 12-speed drivetrains
- Provides Boost 148mm chainline on XCX Mountain cranks and 142mm chainlines on XCX Gravel cranks
- Provides chainline for Superboost spacing on TRS and LG1 cranks

UL Chainrings are not compatible with Helix cranks. Helix cranks require Helix rings available soon.
