Wolf Tooth SRAM Chainring 38t Direct Mount 9/10/11/12-Spd Aluminum Black

Direct mount rings designed for SRAM cranks with removable spiders. This chainring is equipped with the patent pending Drop-Stop asymmetrical tooth design for the best in wear life, mud clearance, and chain retention.Drop-Stop chainrings are designed for use with 1x9, 1x10, 1x11 and 1x12 drivetrains. Compatible with all 10-, 11-, and 12-speed chains, with the exception of Shimano 12-speed chains. Shimano 12-speed chains require the use of Wolf Tooth's Shimano 12-speed specific chainrings. If using a 9-speed drivetrain, use a 10-speed chain, which will provide a tighter fit for better chain retention. Not compatible with the SRAM RED and Force AXS 8-bolt interface. Made from 7075-T6 aluminum for long life. Use of a clutch-style rear derailleur is recommended.
