e*thirteen UL Direct Mount Ultra Light Mountain Bike Chainring

UL Chainrings are the perfect fusion of lightweight construction and exceptional durability for both gravel and gravity race applications, with XCX Gravel/MTB, and TRS/LG1 cranks. Built on the foundation of our successful SL Chainring, with refined arm design and precision machining techniques to significantly reduce weight without compromising impact strength. The M3 narrow-wide tooth profile means amazing chain retention, with less chain noise, and decreased overall system wear, as well as being compatible with Shimano and SRAM 10, 11, and 12s drivetrains.
