WHAT IS POWERCRANK-E?

This is our newest version of a power meter created with modernity in mind. We have equipped the reliable POWERCRANK-E measuring system with a rechargeable battery, which you charge using the included magnetic USB cable. It’s not just a power measuring device, it’s your training partner thanks to which you’ll enter a new level of sportsmanship. The INPEAK POWERCRANK-E power meter uses ANT+ and BLE transmission protocols to send power, cadence and a host of detailed cycling performance data. The low-profile, waterproof and durable housing is designed especially for road and gravel bikes. Precise and accurate readings of generated power regardless of weather conditions are provided by ATC’s automatic temperature compensation mechanism from -5°C to +50°C.
