Shimano Pédalier Ultegra 12V FC-R8100 172.5mm 50-34T

SHIMANO's Ultegra 12V FC-R8100 crankset was designed to boost performance by promoting your speed. This crankset is a real plus that gives you comfort and control. The Di2 components integrated into it also promote greater fluidity in your gear changes thanks to wireless technology.

POWER TRANSMISSION AND OPTIMIZED GEAR SHIFTING
The FC-R8100 is an added value for your bike. It is distinguished by the quality of gear changes and transmission efficiency.
Power transmission and gear changes are optimized by the chainrings that have a Hollowglide construction, as well as by the lightweight crank arms made with Hollowtech 2 technology.
The combination of these elements provides an excellent ratio between rigidity, stability and rotational efficiency.

MINIMIZE YOUR EFFORTS
With the addition of Hollowtech 2 technology, SHIMANO wanted to create a crank that helps minimize your efforts in the race by distributing pedaling power more efficiently. In addition, the fixed connection of the right arm with the axis of the bottom bracket and the external bearing of the latter provides an optimal ratio between rigidity and lightness.
