Precision Power Output Metrics & Realtime Data
The fundamental design principle of Rotor's INpower Direct Mount Road powermeter is integrated power measurement technology inside the axle to precisely record your power output, pedal smoothness, cadence and torque effectiveness to improve your pedaling performance and reach your training goals.
Track your ride with real time data including proprietary metrics TORQUE 360, Optimum Chainring Angle (OCA) and a recommendation of your Optimal Chainring Position (OCP). Combine this key information with Rotor's Q Rings oval chainrings to adjust your OCP and improve your efficiency.
Connect to your cycling device or smartphone via Bluetooth® Smart or ANT+ to get a complete picture of your pedaling performance with analysis platforms such as TrainingPeaks.com. Combined with the free ROTOR power smartphone app, access equivalent metrics and graphs that have previously only been available in biomechanical training labs.
Power is measured in the left leg through two sets of opposing gauges in the axle delivering precise data metrics including power output, cadence, torque effectiveness and pedal smoothness.
Powered via standard AA battery that lasts up to 300 hours, all electronics are housed inside the sealed water-proof axle for centered rotational weight & maximum device protection. INpower DM Road is a powerful tool for measuring your unique pedaling biomechanics via our ROTOR Power application.
