Shimano 105 R7100 50/34T 165mm 12 Speed Bike Double Chainset

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+ 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
