  • Hairpin curves, off-camber turns, mud, sand, snow, and ice define ideal ´cross conditions for you to forge a pace so fast, you see stars. All your other riding experiences only serve to train for 'cross so when you pluck your 'cross bike from your stable of rigs, it needs to roll with the same rhythm and feel as your other bikes. You know that nobody applies constant, even force throughout the pedal stroke, but consistency is key for you, which is why ROTOR sought to improve upon traditional round rings by creating its flagship oval Q-Rings.

    Round rings however, have a place in history and ROTOR wanted to complement its product range by offering round noQCX1 rings for your 1x cranks. 0% ovality noQCX1 chainrings for ´cross offer the performance benefits inherent in round rings for you to go out and attack the barriers, fly-overs, curves or anything else that ´cross throws at you.

  • 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).
    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
