Wolf Tooth 107 BCD Chainrings for SRAM Cranks are compatible with SRAM gravel and road cranks that use the 107 BCD spider, including the SRAM AXS Power Meter Spider. These chainrings use the patented Wolf Tooth Drop-Stop B Wide/Narrow tooth profile that is optimized for 12-speed Eagle and Flattop chains.
- Aero chainrings available in 46-50T. Sizes 38-44T are non-aero.
- Fits SRAM AXS 107 BCD cranks with a removable power meter spider and SRAM 107 BCD cranks with removable spiders.
- Drop-Stop technology prevents dropped chains. On Wolf Tooth’s patented wide/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris while reducing friction.
- SRAM Cranks that use the 107 BCD spider also use the SRAM 8-bolt interface, which is compatible with Wolf Tooth Direct Mount Chainrings for SRAM 8-Bolt
Compatibility
- Designed for SRAM 107 BCD cranksets with removable power meter spiders. Also fits standard SRAM 107 BCD removable spiders without power meters.
- Compatible with SRAM 12-speed and 13-speed groupsets including SRAM Red XPLR AXS.
- Not compatible with SRAM Rival 107 BCD cranksets with integrated (non-removable) spiders. (models ID's FC-RIV-D1 and PM-RIV-D1)
- Chainline is determined by the crank model. See manufacturer specs for chainline.
- Only works for cranks where the chainring mounts in front of the spider. These rings are not compatible with spiders that require the chainring to mount behind the spider, like on certain models of the Specialized Creos.
- Chainrings are designed for 1x drivetrains. They are not compatible with 2x drivetrains.
Recommendations
- If you plan to ride in very extreme or muddy conditions, we recommend a chainguide or chainkeeper (like our LoneWolf or GnarWolf ). Without these precautions, there is the possibility of experiencing chaindrops, even with a proper clutch-style rear derailleur.
- Recommend the use of a clutch-style rear derailleur for the best chain security.
- For non-aero chainring installation, use SRAM chainring bolts and caps. Apply light grease to threads and torque to 12Nm with a T30 bit.
- For Aero Chainring installation, use the included Wolf Tooth chainring bolts. Apply light grease to threads and torque to 8Nm with a 4mm hex bit.
