Wolf Tooth SRAM Aero chainring, 107 BCD, 4-hole, Drop-Stop B - black

The Wolf Tooth Aero chainrings were developed for gravel and road racing and for anyone who wants to optimize every detail in the pursuit of speed. They are robust, lightweight, and profiled to perfectly fit your crankset, providing a clean, integrated Look. The Aero chainrings utilize 1x drive systems and rear cassettes with larger gearing and are available in sizes 46T to 50T to offer a similar overall gearing to standard 2x drive configurations. They feature our patented Drop-Stop® design for best durability, chain retention, and mud clearance. Drop-Stop B is optimized for SRAM Eagle and Flattop chains.

The Wolf Tooth Aero 107 BCD chainrings for SRAM cranks are designed for seamless combination with the SRAM AXS 107 BCD Power Meter Spider.

Features:

• Fits SRAM AXS 107 BCD cranks with removable power meter spider and SRAM 107 BCD cranks with removable spiders
• The Drop-Stop technology prevents the chain from dropping on 1x drives. The patented wide/narrow chainring from Wolf Tooth has the wide side of the tooth with maximum contact on the drive side, distributing the load and improving the chainring's lifespan. The narrow side provides space for mud and dirt while reducing friction
• SRAM cranks using the 107 BCD spider without a power meter also utilize 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, lighter configuration
• Compatible with SRAM 12-speed and 13-speed groups, including SRAM Red XPLR AXS
• Not compatible with SRAM Rival 107 BCD cranksets with integrated (non-removable) spiders. (Models ID FC-RIV-D1 and PM-RIV-D1)
• Chainrings are designed for 1x drives. They are not compatible with 2x drives.
