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. Its individual tooth profile has moved from the traditional symmetrical shape to a 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. Additionally, this Race Face Cinch direct mount chainring uses its Cinch DM system to provide significant weight savings by eliminating the material overlap and extra bolt hardware that is required for a traditional spider with chainring configuration.
This Race Face Direct Mount Oval Chainring is engineered for aggressive MTB use as it uses its ovalised design to give you impressive and powerful torque on the toughest of rides.

Race Face has also equipped this oval chainring with a direct mount profile for fast and easy installation to your ride. Please note: Not compatible with Shimano 12 speed chains.
