WHAT IS POWERCRANK?

This is our most popular version of the power meter created out of passion for cycling. It’s not just a device that measures power, it’s your training partner with which you will enter a new level of sportsmanship. INPEAK POWERCRANK power meter uses ANT+ and BLE transmission protocols to send power, cadence and a lot of detailed cycling performance data. The waterproof and impact-resistant case is designed to meet the demands of MTB, Gravel and Road. POWERCRANK provides a very long run time on the popular CR2023 battery. Precise and accurate readings of generated power regardless of weather conditions are provided by the ATC automatic temperature compensation mechanism from -5°C to +50°C.
