Easton Direct Mount ChainringThis high-quality direct mount chainring is specifically engineered for road, cyclocross and gravel riding disciplines. Its 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. All Easton rings feature the Cinch Direct Mount System making a swap between ring sizes or even between double ring configurations a fast and simple procedure. Additionally, its Cinch DM system also provides significant weight savings by eliminating the material overlap and extra bolt hardware that is required for a traditional spider with chainring configuration.
