ROTOR UNO Gravel: the wireless electronic groupset that redefines modern gravel
Gravel is freedom, adventure, and precision across ever‑changing terrain. For riders looking for a groupset capable of performing on long routes, rough tracks, or fast paved sections, ROTOR UNO Gravel has become one of the most advanced options on the market. Its modular philosophy, ultralight design, and wireless electronic technology position it as a benchmark for cyclists seeking a reliable, configurable setup with a distinctive character.
Designed specifically for gravel: simplicity and 1X performance
The gravel version of ROTOR UNO is built around a 1X configuration, eliminating the front derailleur to reduce weight, simplify maintenance, and increase reliability on loose terrain. This approach is confirmed across multiple sources, highlighting that the gravel variant is optimized for a front‑derailleur‑free design and compatible with cassettes up to 46 teeth.
Additionally, the system offers:
- A compact 75 mm pulley cage, tuned for gravel geometry.
- Compatibility with 10‑ to 13‑speed cassettes, providing a broad range for steep climbs and fast rolling sections.
- Compatibility with 10‑ to 13‑speed cassettes, providing a broad range for steep climbs and fast rolling sections.
Thanks to this architecture, riders can adapt to any terrain without mechanical complications while maintaining consistent shifting precision.
Wireless electronic technology for a modern riding experience
ROTOR UNO adopts a wireless electronic system based on Bluetooth® and ANT+™. This allows a clean installation with no cables and advanced configuration through the official app.
Key technical features include:
- 150 ms gear shifts, ensuring speed even under load.
- Microprocessor‑ and encoder‑controlled system, optimizing precision.
- 600 mAh internal battery with autonomy for up to 15,000 shifts.

This design ensures sensitive, precise braking control, even on technical descents or unpredictable surfaces.
Total modularity: ROTOR’s philosophy applied to gravel
One of ROTOR UNO’s greatest strengths is its modularity, allowing riders to:
- Combine it with any 10‑ to 13‑speed cassette, from any brand.
- Integrate it with different 1X drivetrain configurations.
- Upgrade the bike progressively with new ROTOR cranks, power meters, or cassettes.
- Integrate it with different 1X drivetrain configurations.
- Upgrade the bike progressively with new ROTOR cranks, power meters, or cassettes.
The goal: to avoid obsolescence and let each cyclist build their ideal drivetrain according to their needs, budget, and riding style.
Minimal weight, maximum performance
According to official data, the ROTOR UNO Electronic Gravel Upgrade Kit adds only 1,165 g (levers, brakes, derailleur) to the bike, making it the lightest in its category.
The derailleur and shifter together weigh just 453 g, including the battery.
