We're excited to expand our CINCH system compatibility with the new FLT 12 SPD direct mount chainrings. With sizing from 36t to 44t, our directionally shaped tooth design is optimized to work with Flattop 12 speed chains and the X-Range (from 10-26t to 10-36t) cassettes these systems ship with. While the design is optimized for Flattop chains, these chainrings will also work with 11 speed chains.
