These chainrings are forShimano GRXcranks. They feature our patented Drop-Stopdesign 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.

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.
