Wolf Tooth Direct Mount Chainrings for SRAM 3-Bolt Gravel/Road Cranks Info

Wolf Tooth Direct Mount Chainrings for SRAM 3-Bolt Gravel/Road Cranks offer a clean, lightweight, and highly durable upgrade for modern 1x drivetrains. Designed to replace both the spider and chainring with a single CNC-machined piece, these rings deliver excellent stiffness and reliable power transfer with a simplified, spider-free aesthetic.

Built around Wolf Tooth’s patented Drop-Stop® B wide/narrow tooth profile, the chainring is optimized for SRAM Flattop chains while maintaining compatibility with most 9-, 10-, 11-, and 12-speed drivetrains. The tooth shape provides exceptional chain retention and effective mud shedding, making it a dependable choice for gravel, cyclocross, and all-road riding in variable conditions.

A dedicated 6 mm offset is used to achieve a 47 mm chainline on standard road, CX, and gravel cranksets, ensuring proper drivetrain alignment and smooth operation. Precision-machined from 7075-T6 aluminum, the ring balances low weight with long-term durability for high-mileage riding.
