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.
