Wolf Tooth Drop-Stop B Chainring SRAM Direct Mount 8-Bolt 6mm Offset

Wolf Tooth Direct Mount Chainrings for SRAM 8-Bolt Gravel / Road Cranks simplify your drivetrain by replacing the traditional spider-and-chainring setup with a single, stiff, and lightweight direct-mount solution. CNC-machined from high-strength aluminum, these chainrings deliver clean aesthetics, efficient power transfer, and dependable performance for modern road and gravel builds.

At the heart of the design is Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile, engineered to maximize chain retention, improve wear life, and shed mud effectively. The Drop-Stop B profile is optimized specifically for SRAM Eagle and Flattop chains, making these rings an ideal match for today’s SRAM 12- and 13-speed road and gravel drivetrains.

Designed around the SRAM 8-bolt mounting standard, these direct mount chainrings are compatible with SRAM AXS road cranksets, SRAM Direct Mount DUB road cranks, 2025 Cane Creek eeWings Titanium Cranks (8-bolt), and any crankset using a removable 8-bolt spider interface. Aero profiles are available in larger sizes for riders looking to maximize aerodynamic efficiency at speed.
