  • INpower DM MTB

    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.

  • Why Q-rings?
    Biomechanical studies indicate that the effort made with Q-Rings becomes a greater performance and pedaling feeling more rounded and smooth due to their ability to make a better use of the strongest muscle groups while they also compensate the dead spot in pedaling.
    Q-Ring-Round Ring Comparison
    Far from feeling unusual, a Q-Ring feels much rounder than a round ring. A spinscan analysis visualize a cyclists power delivery, with a bar graph indicating the variation from maximum to minimum output and a polar graph showing the rotating shape of the power profile.

    By comparing the left hand Round chainring spinscan and the right hand Q-Ring spinscan below, one can see that Q-Ring graphs are clearly smoother (less variation in torque in the bar graph) and fuller (less of a peanut shape at the weakest point).
    Spinscan
    When one projects a polar plot of a typical spinscan over the varying drivetrain resistance of a 53t Q-Ring during its rotation, the value of a Q-Ring is clearly visible: Maximum power is met with a “56,5t” Time trial sized chainring diameter and minimum power is met with a “50,4” compact size chainring diameter.
    This variation creates the “perfect spin” we all aspire to, that simply isn’t possible with round chainrings. This is because Q-Rings compensate for the weakest zone of the pedalling stroke and maximize use of the most powerful zone.
    Key benefits (based on ROTOR study)
    • All Q-ring TT’s were faster, with an average gain of 1.6 sec and 0.7 km/h (1.8%).
    • All Q-Ring TT’s generated more power, with average increase of 26.7 W (6.2%)
    • Reduced oxygen consumption and heart rate in submaximal tests
    • An immediate performance increase on switching from round rings to Q-Rings
    • An immediate performance reduction on switching back to round chainrings
    • It also appears that the more effort a cyclist exerts, the greater the benefit of Q’s
