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.
• Compatible with the 107 BCD Spider for SRAM 8-bolt Cranks.
• 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
