Description
Now fitted to Shimano’s latest Ultegra R8100 crank, Stages Cycling’s Left Arm Power Meter offers superb accuracy and ease of operation for anyone wanting to train or race with power data.
Mounted on a left side Ultegra R8100 crank that fits a Shimano Hollowtech II bottom bracket, the power meter only adds 15 grams to the arm and can last for up to 200 hours with its easily-replaced CR2032 battery. Measurement is accurate to ± 1.5% and up to 2500 watts, so should satisfy even the very strongest sprinters.
It is compatible with almost all GPS computers on the market along with online training software such as Zwift and TrainerRoad and it communicates by ANT+ or Bluetooth for a secure and reliable connection. Wireless upgrades ensure that the firmware is up to date and active temperature compensation maintains accuracy when weather conditions change rapidly.
