Integrated power capture at an attractive price. The Shimano Ultegra FC-R8100-P Powermeter crank is in no way inferior to its Dura Ace counterpart in terms of functionality and precision.

The integrated Powermeter sets standards in terms of performance measurement with an optimised accuracy of ±1.5 %. It measures the cadence data and the resulting values on both sides, that means independently for the left and right leg. Thanks to its design, the data collection is also free from external influences such as incline, road surface or wind.

As the central element of the 12-speed drivetrain of the Ultegra R8100 series, the 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.

Various 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.
