Description
The Shimano Ultegra R8100‑P cranks integrate a dual-sided power sensor, designed for cyclists seeking precision and performance. Thanks to sensors placed in both cranks, they deliver an extremely reliable power measurement, with a stated accuracy of ±2%, ideal for analysing left‑right distribution and optimising pedalling efficiency. Compatible with Shimano 12-speed groupsets, they are perfectly suited to intensive training and road racing.
Built with Hollowtech II technology, the R8100‑P cranks combine lightness and stiffness for maximum power transfer. Available lengths from 160 to 175 mm and chainring combinations of 50‑34T or 52‑36T allow precise adjustment to your pedalling style and needs. The hollow construction of the cranks and aluminium chainrings offers excellent resistance while reducing weight, for optimal performance on the road or in time trials.
The power sensor integrates ANT+ and Bluetooth LE connectivity, ensuring seamless communication with GPS computers, training apps and real-time coaching systems. The rechargeable Li‑ion battery offers up to 300 hours of battery life, enabling long training sessions without interruption.
Finally, the R8100‑P cranks are compatible with a wide variety of press-fit bottom brackets, including SM-BB9000 and SM-BB72‑41B. Installation is straightforward and secure thanks to Shimano's precise tolerances, ensuring a stable fit and a pedalling stroke free from energy loss. These cranks are an indispensable tool for ambitious cyclists seeking power, reliability and cutting-edge technology.
