  • Being different is no longer an option. it is the choice you made when you decided to ride against your rivals, against the wind, against yourself.

    Differentiatingourselves in order to evolve led us to develop the first groupset that integrates hydraulic technology from disc brakes into the drivetrain, thus offering a previously unimaginable smoothness without losing neither efficiency nor the tactile command that reminds us who’s in control of the handlebars.

    Pure simplicity because bicycles only need the impulse of passionate people, like the technicians that assemble ROTOR UNO by hand at our factory in Madrid, and who guarantee that each part measures up to the demanding quality standards that mark our products.

    BeautyTimeless design that won’t compromise UNO’s precise functionality thanks to careful manufacturing in limited and numbered series. A unique product that is a work of engineering embodied in carbon fiber and 7075 aluminum parts machined by Computer Numerical Control (CNC)

    Without batteries, without chargers your bike depends only on your efforts to mark the way. Break away.

    Exclusive, lightweight, easy to maintain and technologically distinct, UNO combines the most desirable features of electronic and mechanical systems to create a new category of technological groupsets. In collaboration with Magura, which has created the UNO rim brake system, you will enjoy the advantages of more than a century of experience in the field of hydraulic brake systems. Magura’s RT8 rim brakes feature: more precise braking control thanks to hydraulics; quick wheel release for a dynamic and frictionless wheel change; dirt-resistant design; and easy maintenance.

    Total weight UNO Groupset: 1655 g, which includes shifters, front and rear derailleur, filled, uncut hoses, rim brake calipers and installation hardware; designed for any ROTOR power meter.

    • Includes complete bleed/service kits for both shifting and braking.
    • Same mineral oil used for both shifting and braking.
    • Compatible with all ROTOR cranksets, oval Q-Rings, and round rings

  • 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
