Wolf Tooth 107 BCD Chainrings for SRAM

Wolf Tooth 107 BCD Chainrings for SRAM are engineered for modern SRAM gravel and road cranksets that use a 107 BCD removable spider, including models equipped with SRAM AXS power meter spiders. Designed specifically for 1x drivetrains, these chainrings combine refined wide/narrow tooth shaping with lightweight 7075-T6 aluminum construction to deliver dependable chain retention and efficient power transfer.

Each Wolf Tooth 107 BCD Chainring features the patented Drop-Stop® B wide/narrow tooth profile, optimized for SRAM 12-speed Eagle and Flattop chains while remaining compatible with SRAM 12- and 13-speed groupsets, including Red XPLR AXS. The tooth design maximizes drive-side contact to extend chainring life, while the narrow profile clears mud and debris to maintain smooth performance.

Available in both aero (46–50T) and non-aero (38–44T) configurations, these chainrings allow riders to fine-tune their drivetrain for gravel racing, road performance, or endurance builds. Chainline is determined by the crank model, so refer to SRAM specifications for exact setup.

Compatibility

• Fits: SRAM 107 BCD cranksets with removable spiders, including removable AXS power meter spiders.
• Groupset Compatibility: SRAM 12-speed and 13-speed, including SRAM Red XPLR AXS.
• Drivetrain Type: 1x only (not compatible with 2x drivetrains).
• Mounting Requirement: Only works with cranks where the chainring mounts in front of the spider.
• Not Compatible: SRAM Rival 107 BCD cranksets with integrated (non-removable) spiders (FC-RIV-D1, PM-RIV-D1) and spiders requiring rear-mounted chainrings.

Installation Notes

• Non-Aero Chainrings: Use SRAM chainring bolts and caps. Apply light grease and torque to 12Nm with a T30 bit.
• Aero Chainrings: Use included Wolf Tooth chainring bolts. Apply light grease and torque to 8Nm with a 4mm hex.
