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.

Features

  • Innovative HollowTech forged and anodised aluminium crank arms utilise a hollow design that minimises flex and keeps the weight low

  • The system allows for easier installation, adjustment, and maintenance

About Shimano

Shifting the way the world rides.

From a single Osaka workshop in 1921, Shimano has grown into the world's most influential component maker. The brand's relentless engineering — Dura-Ace, Ultegra, GRX, XTR — has shaped the way the world shifts, brakes and rides, on the road and off it.

Shimano's flagship groupset, Dura-Ace, has been the benchmark for top-level road components for more than five decades. Every refinement that lands on Dura-Ace eventually shapes the entire Shimano range, all the way down to entry-level drivetrains.
