These chainrings are for Shimano GRX cranks. They feature our patented Drop-Stop® design for the best wear life, chain retention, and mud clearance. The newly updated tooth profile works with SRAM Flattop chain in addition to other 9, 10, 11, and 12 spd chains (except Shimano HG+ 12 speed chain). 

Compatibility

  • Shimano GRX cranksets including RX600 and RX810
  • Drop-Stop® FT 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
  • Use Drop-Stop B for all 9, 10, and 11spd chains or 12spd SRAM Eagle, SRAM Flattop, Campagnolo, KMC, Connex or Wippermann chains

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.
