ROTOR UNO rim brake front

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 group set technology. By partnering with Magura to produce UNO's rim brake system, you get the benefit of more than a century's-worth of expertise in hydraulic brake systems. Magura's RT8 rim brakes feature more precise braking control thanks to hydraulics, a quick release for fast wheel changes, and friction-less, dirt resistant design and technology for easy maintenance.
