Wolf Tooth 107 BCD Chainrings for SRAM

Wolf Tooth 107 BCD Chainrings for SRAM Info

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.
