Details |
 Tooth shape is nearly identical to Drop-Stop A, but has narrower teeth. Valley between teeth is deeper to accommodate larger rollers on Flattop chain. Outside faces of narrow and wide teeth touch chain to guide alignment. Drop-Stop B Chainrings |
 The original Drop-Stop tooth profile. The wide teeth are wider than Drop-Stop B. Outside faces of narrow and wide teeth guide chain alignment. Drop-Stop A Chainrings |
 Narrower teeth than Drop-Stop A. Wide teeth use Symmetric Trapezoidal (ST) profile to match extended inner edge on chain to create alignment (outside faces of wide teeth do not touch). Interaction of narrow teeth and chain are similar to Drop-Stop A and B. Drop-Stop ST Chainrings |
*We are in the process of migrating most Drop-Stop A to Drop-Stop B to make them compatible with SRAM Road and Transmission (T-type) Flattop chains.
These chainrings are for Shimano GRX cranks. 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. Drop Stop-B works with all other 9, 10, 11, and 12-spd chains, including SRAM Flattop.
Compatibility
- Aero chainrings available in 46T - 52T. Sizes 36T - 44T are non-aero.
- 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). Non-aero chainrings have no compatibility restrictions and work with 600 and 800 series cranks.
- Drop-Stop ST is designed for Shimano 12-speed Hyperglide+ chains
- Drop-Stop B tooth profile is compatible with SRAM Flattop chain
- Wolf Tooth’s patented Drop-Stop wide/narrow tooth profile provides the ultimate chain retention and mud-shedding ability
- Chainrings are designed for 1x drivetrains. They are not compatible with 2x drivetrains.
Recommendations
- 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.
