The complete Rotor UNO RD group with Caliper hydraulic brakes is exclusive, lightweight, easy to maintain, and features advanced technologies. UNO combines the best characteristics of electronic and mechanical systems to create a new category of technological groups. In collaboration with Magura, the Caliper UNO brake was created, benefiting from over a century of experience in hydraulic braking systems. Magura's Caliper RT8 brakes offer more precise braking control thanks to hydraulics, quick release for wheel changes, a dirt-resistant design, and easy maintenance technology.
