Designed for 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 52T to provide similar overall range to standard 2x drivetrain configurations. They feature our patented Drop-Stop® design for the best wear life, chain retention, and mud clearance. Drop-Stop ST is specifically for the Shimano 12-speed Hyperglide+ chain, which is used by GRX 12-speed.


  • Aero chainrings available in sizes 46T - 52T. Sizes 36T - 44T are non-aero.
  • Compatible with Shimano GRX 800 series cranksets (FC-RX810-1, FC-RX810-2, FC-RX820-1, FC-RX820-2).
  • Aero chainrings are NOT compatible with Shimano GRX 600 series cranksets (FC-RX600-1, FC-RX600-10, RX600-10, FC-RX610-1, FC-RX610-2).
  • Drop-Stop ST is designed for Shimano 12-speed Hyperglide+ chains
  • Wolf Tooth’s patented Drop-Stop wide/narrow tooth profile provides the ultimate chain retention and mud-shedding ability
  • Use Drop-Stop B for all SRAM Eagle, SRAM Road and Transmission (T-Type) Flattop chains, 9, 10, and 11spd chains or 12spd KMC, Connex, Wippermann, Campagnolo.



    • If you plan to ride in very muddy conditions, we recommend a chain guide or chain keeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chain drops and/or chain suck.
