power2max power meter
With the spider-based power2max NGeco power meter, the pedaled power between the crank and chainring is recorded. The power meter uses strain gauges to record the torque and also determines the cadence and the right-left distribution. The pedaled wattage is calculated from the cadence and the torque. The NGeco basically determines the following data: Power (power in watts), cadence (RPM, revolutions per minute) and left/right distribution (in %). It transmits these values to your bike computer via ANT+ or Bluetooth (BLE). An upgrade is available via the power2max app, e.g. Pedal Smoothness (smooth pedaling).
Powermeter features:
- Power meter integrated into the Spider
- Measurement on both sides (left/right distribution)
- Active Temperature Compensation
- wireless data transmission via Bluetooth Low Energy or ANT+
- Upgrades and more via power2max app (e.g. pedal smoothness)
- Firmware update possible
- Cadence measurement via acceleration sensors (no additional magnet required)
- Waterproof
- LED signaling - always informs about battery level or connection status
- 300 hours operating time (tool-free battery change according to CR2450 standard)
- +/- 2% measuring accuracy
