Description

The Shimano Ultegra R8100-P crankset featuresa double-sided power sensor, designed for cyclists seeking precision and performance. With sensors on both sides of the crankset, it offers extremely reliable power measurement, with a claimed accuracy of ±2%, ideal for analyzing left-right power distribution and optimizing pedaling efficiency. Compatible with Shimano 12-speed groupsets, the crankset is ideal for intensive training and road racing.

Manufactured with Hollowtech II technology, the R8100-P crankset combines lightness and rigidity for maximum power transfer. Available lengths from 160 to 175 mm and chainring combinations 50-34 T or 52-36 T allow precise adjustment to pedaling style and specific needs. The hollow crankset design and aluminum chainrings ensure excellent strength while reducing weight, for optimum performance on the road or in time trials.

The integrated power sensor features ANT+ and Bluetooth LE connectivity, guaranteeing seamless communication with GPS meters and training applications. The rechargeable Li-ion battery offers up to 300 hours of autonomy for extended sessions without interruption.

Finally, the R8100-P crankset is compatible with a range of press-fit bottom bracket units, including SM-BB9000 and SM-BB72-41B. Its simple, precise installation guarantees stable mounting and efficient pedaling.
