Inpeak Shimano Ultegra FC-R8100 left crank with power meter

A power meter is a device that measures the power generated during a cyclist´s ride - an essential part of cycling training. The device is mounted on the left arm of the Shimano crankset. ANT + and Bluetooth Low Energy allow you to connect to a wide range of bicycle computers and sports watches. In addition, you can connect INPEAK power measurement with a smartphone and use many applications for data analysis and recording. The use of inertial IMU sensors and data filtering algorithms minimizes the negative impact of vibrations coming from ground unevenness to zero (MTB off-road driving, losses in asphalt, cobble stones). Precise and accurate readings of the generated power regardless of weather conditions are ensured by the automatic ATC temperature compensation mechanism in the range from -5 ° C to + 50 ° C. The meters are waterproof, which ensures reliability in all weather conditions - you don´t have to worry about mud, rain, dust, just ride! Due to the low power consumption, it is rare to replace the battery. Thanks to BLE technology and the INPEAK Manager mobile application, you can wirelessly update the power meters firmware.
The devices are manufactured in the EU. The left crank arm on the bicycle should be replaced with the purchased product
