Description
The INPEAK POWERCRANK Shimano Ultegra R8100 Left Crank Arm Power Meter integrates a single-sided power meter into a genuine Shimano Ultegra FC-R8100 left crank arm. The most popular version in the INPEAK range, it lets you start structured training without changing your chainset or bike.
The sensor combines a gyroscope and accelerometer (IMU) with strain gauges for measurement accuracy of ± 2% across a range of 20 to 2000 W, alongside cadence, torque effectiveness and pedal smoothness. Active temperature compensation (ATC) delivers stable readings from -5°C to +50°C, while the IP67 housing withstands rain, mud and impacts.
Powered by a single CR2032 battery, the POWERCRANK offers up to 200 hours of use. ANT+ and Bluetooth Low Energy ensure compatibility with most cycling computers, watches and apps such as Zwift, while the INPEAK Manager app lets you update the firmware and adjust the scale factor.
Designed and manufactured in Poland, each sensor is individually calibrated before dispatch for reliability confirmed by hundreds of cyclists. One of the best-value crank-arm power meters on the market.
