Shimano FC-R7100 105 Double 12-Speed HollowTech II Chainset
Shimano's FC-R7100 105 Double 12-Speed HollowTech II Chainset is compatible with HollowTech II bottom brackets and offers superlative shifting thanks to Hyperglide+ technology. This also allows wider spacing of the bottom bracket bearings for increased longevity and more efficient power transfer due to the larger bearings and an increased axle diameter.
Weight is kept down without reducing stiffness by using hollow aluminium crank arms and the chainrings are anodised for durability and a smart aesthetic.
