Shimano 105 FC-R7100 2×12-speed Crank – Highly efficient and amazingly lightweight
The FC-R7100 is the matching 2x crank for the 105 R7100 12-speed groupset from Shimano and brings maximum power transfer efficiency to your road bike. At the same time, shifting is as fast and precise as usual. The crank weighs only about 50 grams more than the comparable Ultegra model, which is mainly due to the hollow-formed aluminium crank arms. Thanks to the Hollowtech II design, which has been tried and tested for years, with a fixed 24 mm axle, the ratio of stiffness, performance and weight is just right. The small chainring is made entirely of aluminium, while durable composite is also used on the large chainring. FC-R7100 has an asymmetrical 4-arm bolt circle diameter of 110 mm. It produces a chainline of 44.5 mm and has a Q-factor of 148 mm.

Technology:
Hollowtech II
Shimano Hollowtech II is a crank bottom bracket system designed to achieve an ideal ratio of stiffness, weight and rotational efficiency. It is based on an integration of the bottom bracket and the right crank arm and works with a 24 mm axle or bearing diameter, which has proven to be optimal in terms of stability. In many cases, the bearing cups are on the outside so that the load is better distributed. High-quality precision seals ensure a long service life.
