Designed for gravel and road racing, and for those looking to optimise every detail in pursuit of speed, Wolf Tooth Aero chainrings are strong, lightweight and profiled to fit seamlessly with your crankset for a clean, integrated look. Taking advantage of 1x drivetrain systems and wider-range rear cassettes, Aero chainrings are available in 46T to 50T sizes to offer a similar overall range to standard 2x drivetrain setups. They feature our patented Drop-Stop® design for optimal durability, chain retention and mud clearance. Drop-Stop B is optimised for SRAM Eagle and Flattop chains.

Wolf Tooth Aero 107 BCD chainrings for SRAM cranks are designed to pair seamlessly with the SRAM AXS 107 BCD Power Meter Spider.

Fits the SRAM AXS 107 BCD Spider power meter and the SRAM 107 BCD Spider

Drop-Stop technology prevents chain drop. On Wolf Tooth's patented wide/narrow chainring, the wide side of the tooth has maximum contact with the drive side, which distributes the load and improves chainring life. The narrow side allows mud and debris to clear whilst reducing friction.

SRAM cranks that use the 107 BCD spider without a power meter also use the SRAM 8-bolt interface, which is compatible with Wolf Tooth Aero Direct Mount chainrings for SRAM 8-bolt, which we recommend for a cleaner and lighter setup.

Compatibility

Designed for the 107 BCD Spider power meter. Fits standard 107 BCD spiders.

The chainline is determined by the crank model. See manufacturer specifications for chainline.

Use Drop-Stop B for all SRAM Eagle, SRAM Road and Transmission (Type T) Flattop chains, 9, 10 and 11-speed chains, or KMC, Connex, Wippermann, Campagnolo 12-speed chains.
