FC-R7100 105 double 12-speed chainset, HollowTech II 172.5 mm 50 / 34T, black
 
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
