Revolutionary within the cycle industry, Rotor have developed and honed a hydraulic groupset that offers lightning-fast shifting, actuated precision and greater efficiency. Honed and developed alongside Magura, the UNO Hydraulic Road Rim Brake Groupset weighs in at a mere 1655 grams thanks to its durable carbon construction, and offers Magura's unrivalled hydraulic braking and gear shifting capabilities.

Keeping the net weight down, the carbon fibre construction is incredibly durable, making this groupset a reliable option for the discerning rider. Carbon material implemented right down the shift levers provide a rigid platform that not only boasts sublime style, but outputs power with greater efficiency.

Inspired by the precise and smooth shifting abilities of electronic gearing, Rotor have developed the UNO's front and rear derailleur with synchronised internal mechanics, ensuring that each gear shift is actuated with accuracy and stability. Compatible with both round chainrings and Q-Rings, the front derailleur has been created with 4Trim adjustment, offering fine-tuning via a single smart bolt, which also allows for easy maintenance. A Multishift setup on the rear derailleur means you can customise your shifting style, with the ability to shift as many as four gears at once.

Retaining the low weight attributes of this groupset, the 118-link UNO chain and 11-28 tooth cassette ensure that each pedal stroke is rewarded with silky smooth shifting. The CNC machined cassette, claimed to be the lightest ever made, is a two-piece structure shaped with FlowDrive teeth and ramps that provide successive gear transitions with greater accuracy and speed. The X-shaped plates of the chain combined with the reliable performance of the UNO cassette ensure greater chain stability with split-second gear transmissions.

Ergonomically designed to fit almost any rider's hand with excellent comfort and offering a secure grip, the shift levers have been designed with a grooved hood that provides you with an excellent platform even through the wettest and bumpiest of rides. Easy to operate, the broad lever style maintains shifting and braking confidence through an array of riding conditions. Operating via a hydraulic system, these levers are a prime example of Rotor's and Magura's high quality shifting and braking functionality.

At the heart of this groupset is the exceptional braking performances of the rim brake calipers. Incredibly lightweight and aero, these calipers feature an Air-alliance style that integrates flawlessly with the chainstays and fork, ensuring drag is kept to a minimal and airflow is increased.

This completely closed system reduces the frequency of maintenance, making this the ideal option for the riders wanting to spend more time pounding out power than fiddling with tools.
