  • Detail
    • 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
