  • Lightweight 12-speed 2-piece design chainset
  • Innovative forged and anodised aluminium crank arms for minimum flex
  • The chainring teeth have been developed to work in conjunction with Hyperglide&plus 12-speed chains for increased contact to provide greater efficiency and improved power transfer
  • 2-piece design bottom bracket bearings to be spaced wider apart; enabling the use of larger bearings and an increased axle diameter
  • Can be used with Shimano external or press-fit bottom brackets
  • The system allows for easier installation; adjustment; and maintenance
  • Lightweight anodised aluminium chainrings for smooth and precise shifting
