Shimano Ultegra FC-R8100 crankset – 2×12-speed – black

As the central element of the Ultegra R8100 series' 12-speed drivetrain, the FC-R8100 crankset is characterized by Shimano's signature shifting quality and transmission efficiency. Optimized power transmission and faster, more precise shifting are achieved not only by the chainrings, which feature a Hollowglide hollow construction, but also by the lightweight crank arms manufactured using Hollowtech II technology.

Overall, this results in a perfect balance between stiffness, stability, low weight, and rotational efficiency. Numerous crank arm lengths and gradations with 50-34 or 52-36 teeth also offer variability and an optimal gear ratio for almost any riding situation.
