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.
Tanpan - allows Shimano mountain bike rear derailleurs to be used with Shimano road shifters
