E*thirteen Ultralight Guidering (5mm Boost)

The E*Thirteen Ultralight Guidering is a direct mount chainring designed for XCX, TRS, and LG1 cranks. It features an updated M3 narrow-wide tooth profile that eliminates chain noise and decreases overall system wear while retaining the chain. This chainring is compatible with 10, 11, and 12 speed drivetrains from both Shimano and SRAM. It provides a Boost 148mm chainline on XCX Mountain cranks and 142mm chainlines on XCX Gravel cranks, while also providing chainline compatibility for Superboost spacing on TRS and LG1 cranks.
