The Inpower direct mount road crankset provides precise and comprehensive data to improve your pedal stroke performance. Whether you're competing, training or wanting to improve your riding, this stunning component provides all the tools you need to take your performance to the next level. This model measures your pedalling power in the left leg through two sets of opposing gauges in the axle for precise data metrics including power output, cadence, torque effectiveness and pedal smoothness. Powered via standard AA battery, this state-of-the-art model lasts up to 300 hours and all of its electronics are housed inside a special sealed water-proof axle for centred rotational weight and maximum device protection. This is a powered tool for measuring your unique pedalling biomechanics via the Rotor Power application. Access real-time performance rich data including proprietary metrics Torque 360, Optimum Chainring Angle (OCA) and a recommendation of your Optimal Chainring Position (OCP). Combine this key information with Q RINGS oval chainrings to adjust your OCP in 1 of 5 different positions for fine-tuned pedalling efficiency and maximise transmission of power in your unique pedal rotation. Easily connect to your smartphone or cycling device via Bluetooth Smart or ANT+ and export your data for training analysis with various programmes such as TrainingPeaks.com.
