The Wolf Tooth 107 BCD chainring is a premium 1x-specific upgrade designed for SRAM AXS power meter spiders and cranks. Specifically engineered to convert standard 2x setups to a simplified 1x system, this ring features Wolf Tooth’s patented Drop-Stop® technology to ensure maximum chain retention and mud shedding on road, gravel, and CX courses.
Drop-Stop® Technology: Utilises a wide/narrow tooth profile that matches the inner and outer links of the chain, preventing chain drop without the need for a bulky chain guide.
Optimised for SRAM AXS: Specifically designed to fit 107 BCD 4-bolt SRAM cranksets (like Force and Rival AXS), providing a perfect chainline for 12-speed wireless drivetrains.
Multiple Tooth Count Options: Available in a wide range of sizes (typically from 36T to 44T+) to allow you to fine-tune your gearing for flat-out racing or steep, technical climbing.
Superior Mud Shedding: The tooth profiles include recessed areas that allow mud and debris to escape, maintaining efficiency and grip in the most demanding cyclocross or gravel conditions.
High-Strength Aluminium: CNC machined from 7075-T6 aluminium for an incredible strength-to-weight ratio and long-term durability against abrasive road grit.
American Engineering: Designed and manufactured in the USA with strict quality control to ensure perfectly flat rings and precise shifting.
✅ Gravel & CX Conversions: The best way to simplify your SRAM AXS drivetrain into a lightweight, reliable 1x setup.
✅ Chain Security Enthusiasts: If you’re tired of dropped chains on rough terrain, Wolf Tooth’s tooth profile is widely considered the industry benchmark for retention.
✅ Precision Gearing: With multiple tooth count options, you can swap rings easily to match the specific profile of your next race or weekend adventure.
❌ Standard 110 BCD Cranks: This ring is strictly for the 107 BCD interface; it will not fit older 5-bolt or 110 BCD 4-bolt cranks.
❌ 2x Drivetrain Needs: This is a dedicated 1x ring with no shifting ramps; it cannot be used in a double-chainring configuration.
When ordering your Wolf Tooth 107 BCD ring, make sure to select the "Drop-Stop B" version if you are running a SRAM Eagle or Flattop (AXS Road) chain. The "B" profile is slightly narrower to accommodate the tighter tolerances of these chains. Also, check your chainring bolts; because these rings are often thicker than standard 2x rings to ensure stiffness, you might need Wolf Tooth’s specific 6mm chainring bolts for a perfect, flush fit!
