Designed for gravel and road racing, and for those looking to optimize each detail in pursuit of speed, Wolf Tooth Aero Chainrings are strong, lightweight, and profiled to mate perfectly with your crankset for a clean, integrated look. Taking advantage of 1x drivetrain systems and wider-range rear cassettes, Aero Chainrings are available in sizes 46T to 50T to provide similar overall range to standard 2x drivetrain configurations. They feature the patented Drop-Stop® design for the best wear life, chain retention, and mud clearance. Drop-Stop B is optimized 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. SRAM Cranks that use the non-power meter 107 BCD spider also use the SRAM 8-bolt interface, which is compatible with Wolf Tooth Aero Direct Mount Chainrings for SRAM 8-Bolt, which are recommended for a cleaner, lighter weight setup.
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.
