SHIMANO Ultegra crank 2-speed FC-R8000
The medium class Primus among the switching groups in a new guise! The black and anthracite R8000 component group not only improves the appearance of your bike with its distinctive, coordinated design, but also technically makes the Ultegra a big step forward. This is partly due to the Dura Ace 9100 technologies.
With the stylish design of the Ultegra R8000 Hollowtech 2 crank set, weight could be saved without compromising stiffness. Thus, the crank helps you to convert even more force into speed. A wide range of chainring combinations covers all types of wheels from the CX and gravelbike to the time machine. Due to the precise coordination of chainrings, derailleurs and derailleur, the gearshifts are extremely fast and reliable.
