Wolf Tooth Aero 107 BCD Chainrings for SRAM cranks are purpose-built for gravel and road racers who prioritize every detail in the pursuit of speed. These lightweight, high-strength chainrings are profiled for a sleek, integrated appearance and are optimized for use with 1x drivetrains and wide-range cassettes. Available in 46T to 50T sizes, they provide gearing comparable to traditional 2x setups while simplifying your drivetrain for improved reliability and performance. Each chainring features Wolf Tooth&';s patented Drop-Stop B tooth profile, which is optimized specifically for SRAM Eagle and Flattop chains. This design maximizes chain retention, enhances durability, and sheds mud and debris for consistent performance across varied terrain. Designed to pair seamlessly with SRAM AXS 107 BCD cranksets that have a removable power meter spider, these chainrings also fit standard 107 BCD cranksets without power meters. Riders using SRAM&';s 8-bolt interface with non-power meter spiders may prefer Wolf Tooth&';s Aero Direct Mount Chainrings for a cleaner and lighter setup. Compatibility: Fits SRAM 107 BCD cranksets with or without removable power meter spiders 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) spider For muddy conditions, use a chain guide or keeper with a clutch-style rear derailleur to reduce risk of chain drop Key Features: Aero-profiled design: Available in 46T to 50T for clean aesthetics and reduced drag Drop-Stop B tooth profile: Boosts chain retention, durability, and debris clearance Chain compatibility: Optimized for SRAM Eagle and Flattop 12-speed and 13-speed chains Crankset compatibility: Works with SRAM 107 BCD cranks with removable spiders and AXS power meter spiders 1x drivetrain specific: Ideal for wide-range gravel and road setups
