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.
