Keep your gravel drivetrain running clean and quiet, even when the trail turns to slop. The Wolf Tooth 110 BCD Asymmetric 4-Bolt Chainring is built specifically for Shimano GRX cranksets, pairing Wolf Tooth's patented Drop-Stop® tooth profile with precision USA machining for a ring that holds the chain where it belongs.

Every tooth on this ring is shaped to match your chain rather than compromise across chain types. Drop-Stop ST is tuned for the Shimano 12-speed Hyperglide+ chain used on GRX 12-speed groups, while Drop-Stop B covers 9, 10, 11, and 12-speed chains, including SRAM Flattop. That fit-for-purpose engineering is what keeps the chain centered on the ring, reducing drops, extending wear life, and letting mud clear instead of pack in.

Each ring is CNC-machined from 7075-T6 aluminum at Wolf Tooth's shop in Minnesota, with sizes spanning 36T to 52T and aero profiles offered from 46T up for riders chasing every bit of efficiency.

Why Riders Choose This Chainring

Gravel and cyclocross courses throw everything at a drivetrain — mud, roots, washboard, and sudden gear changes. A chainring that isn't matched to your chain will let it bounce and drop at the worst moment. Wolf Tooth solves that by engineering separate tooth profiles for separate chain designs instead of forcing one shape to do everything. The result is a ring that stays quiet, stays clean, and stays on your bike for years, with Wolf Tooth's right-to-repair support behind it if anything ever needs replacing.

Upgrade your Shimano GRX setup with the Wolf Tooth 110 BCD Asymmetric 4-Bolt Chainring — precision-matched to your chain and machined to last.
