    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.

    The groupset with the lightest disk brakes in the market
    Better braking modulation and greater safety in any conditions

    Break away from the rest with ROTOR's hydraulic actuated groupset: UNO.

    Exclusive, lightweight, low maintenance, and technologically distinct, UNO merged the most-desirable characteristics of both electronic and mechanical systems to forge a new category of groupset technology. By partnering with Magura to produce UNO's disc brake system, you get the benefit of more than a century's-worth of expertise in hydraulic brake systems. Thanks to hydraulics, Magura's MT8 disc brakes feature high braking force when you need to slow down fast.

    Total weight UNO Groupset: 1655 g, which includes shifters, front and rear derailleur, filled, uncut hoses, flatmount calipers,160mm brake rotors; designed for any ROTOR power meter.

    • Includes complete bleed/service kits for both shifting and braking.
    • Compatible with standard postmount frame/fork, and most standard flatmount frames with adaptors.
    • 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
