Shimano FC-R7100 Crankset 105 Hollowtech II 12-Speed 50x34T

The FC-R7100 is the matching 2-speed 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.
