Lightweight HollowTech II 105 10 speed triple Chainset

Innovative HollowTech forged and anodised aluminium crank arms utilise a hollow design that minimises flex and keeps the weight low

HollowTech II allows the bottom bracket bearings to be spaced wider apart (outboard from the frame), enabling the use of larger bearings and an increased axle diameter

The system allows for easier installation, adjustment, and maintenance

Lightweight anodised SG-X aluminium chainrings for smooth and precise shifting
