  • 2INpower DM Road

    Accurate power measurement and pedal stroke optimization are fundamental in the pursuit of performance gains.

    Integration of power measurement technology at the core of the crankset design means 2INpower DM Road provide precise and comprehensive data to improve your pedalling performance.

    Higher data sampling rates are achieved by recording power via 4 sets of opposing gauges to measure left and right legs independently to provide precise data about your pedal stroke balance, power output, cadence and torque effectiveness.

    Dual leg measurement allows you to know the individual performance in each of your legs and gives you a comprehensive picture of the power balance in your pedalling technique to highlight where you can make essential improvements.

    2INpower DM Road 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 2INpower DM Road to your cycling device or smartphone via Bluetooth Smart or ANT+ and easily export your data to deep dive into your training analysis with various platforms such as TraingingPeaks.com

    Direct Mount technology includes a clever spline interface between the crank arm and chainrings for superior stiffness and direct transfer of your pedalling torque.

    User-friendly setup and simple calibration with rechargeable battery life of up to 250 hours that can be easily charged via magnetic connector.

    • Power
    • Cadence
    • Balance
    • Torque effectiveness and pedal smoothness for each leg via standard ANT+ protocol and Bluetooth Smart

  • 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
