Description
- 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
