Shimano FCR7000 105 Double Chain set HollowTech II 170 Mm 53 39T
Lightweight HollowTech II 105 11-speed chain set Innovative HollowTech forged and anodised aluminium crank arms utilize a hollow design that minimizes flex and keeps the weight low.
The chain ring teeth have been developed to work in conjunction with HG-X 11-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 SG-X aluminium chain rings for smooth and precise shifting.
