Lightweight HollowTech II 105 10-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 the CN-5701 chains for increased contact to provide greater efficiency and improved power transfer
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
For use with ST-5700, ST-6700 or ST-7900
