SHIMANO 105 crank FC-R7100 12-speed | 50-34
The wait is finally over. Shimano's racing bike group finally comes for the ambitious hobby cyclist with contemporary Di2 technology and 12-speed speed drive. And all of this at an incredibly affordable price-performance ratio. Nevertheless, no compromises were made in terms of durability and functionality and the Japanese's many years of experience can be seen in every detail.
The 105 crank not only converts your pedal power into propulsion, its high rigidity also ensures extremely fast and precise shifting behavior. This is supported by the optimized tooth design of the chainrings. The latter also increase aerodynamics due to their integrated design. In order to keep the weight as low as possible, the Japanese continue to rely on the tried and tested Hollowtech II design of the crank arms.
