Oval 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 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.         Related Products 10mm Chainring Bolts Tanpan - allows Shimano mountain bike rear derailleurs to be used with Shimano road shifters RoadLink - allows for wide range cassettes to be used with Shimano road rear derailleurs Tech Specs Weight:  3 8t • 72g  |  42t • 92g  |  46t • 102g  |  46t (Aero) • 119gMaterial: 7075-T6 aluminum Chainline: 50mm (same as Shimano GRX chainrings)Made in the USA Patent and trademark information
