As the central element of the 12-speed drivetrain of the Ultegra R8100 series, the FC-R8100 crankset is characterised by the shifting quality and transmission efficiency typical of Shimano. Not only the chainrings which feature a Hollowglide construction, but also the lightweight crank arms which are manufactured using Hollowtech II technology, contribute to optimised power transmission as well as faster and more precise shifting operations.
All this adds up to a perfect balance between stiffness, stability, light weight and rotational efficiency. Numerous crank arm lengths and chainrings with 50-34 or 52-36 teeth also offer variability and an optimal gear ratio for almost every riding situation.
