Wolf Tooth Components 110 BCD Asymmetric 4-Bolt Chainrings for Shimano GRX Cranks

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 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 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. Tech Specs Weight:  36t • 65.5g  |  38t • 72g  |  40t • 84g  |  42t • 89g  |  44t • 92g  |  46t • 102g
