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 chainring available in 46T. Sizes 38T and 42T are non-aero.
• Shimano GRX cranksets including RX600 and RX810
• 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
  

Recommendations

• If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuck.
