Wolf Tooth Aero Direct Mount Chainring for SRAM 8-Bolt Gravel / Road Cranks

Wolf Tooth Aero Direct Mount Chainring for SRAM 8-Bolt Gravel / Road Cranks is built for riders who demand aerodynamic efficiency, drivetrain simplicity, and uncompromising 1x performance. Designed specifically for SRAM’s 8-bolt direct mount interface, this aero chainring replaces both spider and ring with a single, stiff piece of precision-machined 7075-T6 aluminum.

For gravel racers and road riders chasing marginal gains, the aero profile integrates cleanly with compatible cranksets to reduce drag and create a refined, purpose-built look. Paired with modern wide-range cassettes, the 46T–52T sizes deliver gear range comparable to traditional 2x setups—without front shifting complexity.

At its core is Wolf Tooth’s patented Drop-Stop® B wide/narrow tooth profile, optimized for SRAM Eagle and Flattop chains. The alternating tooth pattern maximizes chain retention, improves wear life, and enhances mud clearance in demanding race conditions.
