ROTOR bottom bracket Road

  • The UBB is a concept that encompasses and works with ALL BB standards, forever eliminating complicated BB/Crank compatibility problems. There is always a UBB crank to fit your bike irrespective of its BB type. What’s more, there is almost always an unexpected UBB30 upgrade solution for non 30mm frames!

    Simplicity and compatibility
    The UBB (Universal Bottom Brackets) system is not a standard, it’s all standards. Its UBB30 axle allows installation of almost any 30 or 24mm axle crank from ROTOR on, irrespective of BB type, because it encompasses all bottom bracket standards on the market. This allows for surprising and unexpected new options for upgrading bikes of any BB type.

  • 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
