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 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 chainrings for smooth and precise shifting
Package:OEM, No wrapping
