  • Lightweight HollowTech II 105 12-speed chainset
  • Innovative HollowTech forged and anodised aluminium crank arms utilise a hollow design that minimises flex and keeps the weight low
  • 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
  • HollowTech II allows the 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
