Description

Shimano Ultegra R8100-P cranks feature a double-sided power sensor, designed for cyclists seeking precision and performance. With sensors in both cranks, they offer 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, they are ideal for intensive training and road racing.

Manufactured with Hollowtech II technology, R8100-P cranks combine 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 your pedaling style and needs. The hollow design of the aluminum cranks and chainrings offers excellent strength while reducing weight, for optimum performance on the road or in time trials.

The power sensor integrates ANT+ and Bluetooth LE connectivity, ensuring seamless communication with GPS meters, training apps and real-time coaching systems. The rechargeable Li-ion battery offers up to 300 hours of autonomy, enabling long training sessions without interruption.

Last but not least, R8100-P cranks are compatible with a wide variety of press-fit bottom brackets, including SM-BB9000 and SM-BB72-41B. Installation is simple and safe thanks to Shimano's precision tolerances, guaranteeing stable assembly and pedaling without loss of energy. These cranks are an indispensable tool for ambitious cyclists looking for power, reliability and cutting-edge technology.
