Easton direct mount rings use a new 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.

Optimized for 11 speed drivetrains, though compatible with 9, 10 speed chains, as well as 12 speed Eagle, 12 speed Campagnolo.

Not compatible with Flattop AXS or 13 Speed Campagnolo.

Features:

• EA90 SL Alloy
  
• Cinch System Compatible
  
• Variable Tooth Width
  
• Optimized Retention via Directional Tooth Design

Note: Rings only. Crankarms and spindles sold separately.
