ROTOR UNO: A New Wireless Gravel and MTB Groupset | 3bikes.fr, your Cycling, Gravel & Triathlon magazine

ROTOR Bike Components unveils its new wireless electronic groupset, the ROTOR UNO, dedicated to gravel and mountain bikes, at Sea Otter Europe in Girona. This launch marks a major step for the Spanish company, known for its innovations such as Q Rings oval chainrings, power meters, and carbon cranks.

Advanced Technology for Optimal Performance

The ROTOR UNO stands out with its wireless digital electronic technology, offering precision, speed, and lightness. Designed to meet the demands of modern cycling, this modular groupset adapts to 10 to 13-speed cassettes, ensuring unparalleled versatility. The interchangeable components, built around a base groupset, allow for evolution according to cyclists’ needs and budgets, from mid-range to high-end.

ROTOR UNO Gravel: Simplicity and Performance

The gravel groupset uses the same rear derailleur as the MTB version, but with a specific aluminum derailleur cage (75 mm) for better durability and reduced friction. Designed for 1X configurations (without a front derailleur), it supports cassettes up to 11-46 teeth, simplifying and lightening the overall setup.

Carbon levers: silicone coating for ergonomics adapted to wet conditions, with a titanium clamp to limit corrosion.
Hydraulic braking: horizontal master cylinder, adjustable stroke (26 mm), compatible with 160 mm rotors (Center-Lock or 6-bolt) and flat-mount calipers (post-mount adaptable).
Competitive weight: combined with the ROTOR 12-speed cassette (11-46, 294 g), the groupset outperforms its competitors.

ROTOR UNO MTB: Lightness and Connectivity

The MTB groupset consists of a rear derailleur and a handlebar shifter, for a total weight of 453 g (battery included). Equipped with Bluetooth® and ANT+™ connectivity, the derailleur is configurable for 10 to 13-speed cassettes, adapting to all MTB disciplines. Its aluminum and reinforced nylon body, combined with an optimized parallelogram, offers an excellent weight-to-stiffness ratio.

Battery: 600 mAh, up to 15,000 shifts.
Shifting speed: 150 ms per gear.
Derailleur cage: aluminum, 93 mm, compatible with cassettes up to 52 teeth.
Shifter: ergonomic, lightweight, IP67 certified (waterproof), powered by a CR2032 battery.

ROTOR leaves the choice of rotors and calipers to the user, encouraging customization according to preferences and disciplines.

Modularity and Customization

ROTOR is committed to a sustainable approach, far from planned obsolescence. The UNO groupset is compatible with cassettes from different brands and aluminum or carbon cranksets, with or without an INspider power meter. The premium combination includes the Aldhu carbon crankset, the 12-speed 11-52 cassette (314 g), and the INspider sensor.

ROTOR UNO Mobile App

Available on iOS and Android, the app allows you to configure the groupset, adjust cassettes, monitor battery, and customize options. OTA (Over The Air) software updates ensure an always up-to-date system. A future version will integrate metrics from the ROTOR Power app.

A New Era for ROTOR

With the ROTOR UNO, the Madrid-based company strengthens its position in professional and amateur cycling, offering a technological and flexible alternative for gravel and MTB. ROTOR also announces the upcoming presentation of its road groupset, confirming its ambition to innovate.

This launch is part of a dynamic reinforced by the arrival of Lanxi Wheeltop Cycle Industries LTD in ROTOR’s capital, optimizing production between Asia and Spain for increased competitiveness.
