Improve your pedaling performance and reach your training goals with INpower DM MTB’s integrated power measurement technology that forms the core structure of the crankset design. Power is measured in the left leg via two sets of opposing gauges in the axle delivering precise data metrics including power output, cadence, torque effectiveness and pedal smoothness. INpower DM MTB houses powermeter technology inside the crank axle protecting it from rocks, knocks & crashes or contaminants like mud, sand and clay. INpower DM MTB is a powerful tool for measuring your unique pedaling biomechanics via our 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. Connect your INpower DM MTB to your cycling device or smartphone via Bluetooth® or ANT and easily export your data to deep dive into your training analysis with various platforms such as TraingingPeaks.com. User-friendly setup and ease of calibration. Powered via standard AA battery that lasts up to 300 hours with a robust water resistant cover to IP7 standard. Customise and protect your crank arms with rubber bumpers in a choice of seven stylish colours to set your bike apart: black, blue, green, yellow, red, pink, or orange. * Chainrings sold separately.
