Description
SHIMANO 105 crank FC-R7100 | 2x 12-speed
The wait is finally over. Finally, Shimano's road bike groupset for the ambitious hobby cyclist comes with modern Di2 technology and 12-speed speed drive. And all this at an unbelievably low price-performance ratio. Nevertheless, no compromises were made in terms of durability and functionality and the many years of experience of the Japanese can be seen in every detail.
The 105 crank not only converts your pedal power into propulsion, with its high rigidity it also ensures extremely fast and precise shifting. 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 proven Hollowtech II design of the crank arms.
