These chainrings are designed for Shimano GRX cranks. They feature our patented Drop-Stop® design for optimal durability, chain retention, and mud clearance. The newly updated tooth profile works with the SRAM Flattop chain in addition to other 9-, 10-, 11-, and 12-speed chains. Drop-Stop ST only works with the Shimano HG + 12-speed chain!

The Drop-Stop® FT tooth profile is compatible with the SRAM Flattop chain. Wolf Tooth's patented Drop-Stop® design ensures better chain retention, dirt rejection, and less wear.

Chain compatibility: Drop-Stop FT (FlatTop) chainrings are designed for all 10-speed and 11-speed chains. They also work with 12-speed SRAM Flattop, SRAM Eagle, and KMC chains. They do not work with the Shimano 12-speed Hyperglide + chain. Shimano 12-speed chains require the use of our Shimano 12-speed specific chainrings. We recommend using a 10-speed chain when using a 9-speed drivetrain.
