Spezifikationen erklärt
Battery lifeUp to 226+ hours (depending on ANT+/Bluetooth LE settings)
Longer battery life helps long rides and reduces charging stops. Racers and touring riders should plan charging or spares. Stated life depends on use conditions; check charge before setting out.
Accuracy<1.5% strain gauge accuracy across calibration range
A smaller stated measurement error helps structured training and comparing efforts. Recreational riders often benefit more from consistency than the smallest percentage. Compare different meters carefully and follow calibration instructions.
ConnectivityBluetooth LE and ANT+
Check that your head unit or training app supports the protocol. Reliable pairing matters more than many features for structured training. Calibrate as instructed, especially after installation or when required, to avoid misleading power readings.
