Shimano 105 FC-R7100 12-speed crankset

The 105 Hollowtech cranks from the 12-speed R7100 series are compatible with the mechanical and electronic 12-speed drivetrains of the 105, Ultegra and Dura-Ace.

Visually appealing and lightweight aluminium crankset with hollow crank arms for greater stiffness and durability. The newly developed cranks offer a perfect balance between efficiency and low weight. Made from aluminium, the crankset is black anodised and offers a look that is as attractive as it is luxurious. The plastic ribs on the back of the chainrings are a hallmark of the unique structural design of the Shimano 105, enabling significant weight savings whilst delivering crisp shifting performance.
