The anchor of the world's most efficient drivetrain ecosystem. The aggressive architecture of the SRAM X-SYNC 2 Eagle chainring wasn't born in a vacuum, it was forged from the forensic analysis of thousands of battle-worn rings. By engineering a longer, positive-rake tooth profile to mesh flawlessly with the Eagle chain, SRAM achieved a mechanical paradox: absolute, vice-like chain retention that simultaneously reduces friction, silences drivetrain chatter, and drastically extends overall wear life. ________Key Features: X-SYNC 2 chainring design increases chain retention, wear life, and reduces friction and noise. Material: forged and machined aluminum Finish: Anodized Compatibility: Eagle 12-speed, or Sram 11-speed Designed to be used with Eagle chains SRAM Direct Mount Compatibility ________Specifications: CHAINRING SIZE 32T, 34T, 36T, 38T BOLT CIRCLE DIAMETER (BCD) 104 BCD SPEEDS 11, 12 COMPAT - YAW No MATERIAL (CHAINRING) Aluminum COLOR (CHAINRING) Black
