Product Details

The iconic Hollowtech II hollow forged crank has always been a benchmark for strength to weight performance characteristics and is the perfect platform for a crank intended to be used at the highest echelon of competition. Combined with a hollow outer chainring the crankset is 20% stiffer for optimal power transfer while still saving 15 grams. Other changes include redesigned chainring teeth for better contact and power transfer. Improved bottom bracket seals further reduce contamination and friction.

  • Thin-walled forged aluminum crank for weight savings by trimming unnecessary material
  • Hallow chainring for weight savings while maintaining strength
  • All gears are usable with no cross-chainring problems when used with CN-7900 chain
  • New seal design for the bottom bracket interface for smoother rotation and longer durability
  • 690 gram total system weight
