Easton Direct Mount CINCH Chainring – 40t 12-Speed For Flattop Chains Black. The Easton direct mount CINCH chainring for Flattop chains has an updated tooth profile optimized for SRAM Flattop 12-speed chains. They use a narrow/wide design specifically tailored to road/cx/gravel applications. The individual tooth profile has moved from the traditional symmetrical shape to more directional specific design with the intention to create a positive chain roller engagement to help with chain retention critical to prevent chain slip and bounce over rough terrain.
The CINCH direct mount system provides weight savings and makes swapping chainrings fast and simple
