  • INpower 3D30 BCD110

    Taking its design cues from the INpower 3D+, the INpower 3D30 offers the same sophisticated metrics integrated inside the crank axle of all INpower models. The forged and CNC'd 3D30 is enhanced by proprietary TDS triple drilling technology to yield the perfect weight:stiffness ratio, and its compact crank spider offers a wide range of chainring compatibility without compromising stiffness.

  • 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
