Quality Shifting, Lightweight Design

As the central element of the 12-speed drivetrain of the 105 R7100 series, the FC-R7100 crankset is characterised by the shifting quality and transmission efficiency typical of Shimano. Not only the chainrings which feature a Hollowglide construction, but also the lightweight crank arms which are manufactured using Hollowtech II technology, contribute to optimised power transmission as well as faster and more precise shifting operations.

All this adds up to a perfect balance between stiffness, stability, lightweight, and rotational efficiency.

Hollowtech II

The guiding principle of Shimano's Hollowtech II technology is the perfect balance between stiffness, stability, weight, and rotational efficiency. The goal was to produce a crank that minimises the effort required for the drive and enables more efficient power transmission.

An exclusive forging process allows the production of extremely light crank arms that nevertheless guarantee maximum stiffness. The fixed connection of the right arm to the axle of the bottom bracket and its external bearing also serves an optimum relationship between stiffness and low weight.
