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.
