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. Wolf Tooth 107 BCD Chainrings for SRAM Specs at a Glance BCD: 107mm.
