Campagnolo: Italian Shifting Artistry
The traditional Italian brand Campagnolo stands for the highest quality and unique design. Both the mechanical gravel groupset Ekar and the electronic Super Record 13 embody Italian engineering excellence. Campagnolo rear derailleurs work perfectly with 12-speed and the latest 13-speed cassettes and offer an unmistakable shifting feel.
Shimano Rear Derailleurs: Japanese Perfection
Shimano is synonymous with reliable shifting technology and offers both mechanical and electronic solutions. Ultegra and Dura-Ace rear derailleurs impress with butter-smooth shifting performance and longevity. For the highest demands, the electronic Di2 technology provides lightning-fast, precise shifts at the push of a button. Shimano rear derailleurs are available in 11-speed and 12-speed versions and offer broad compatibility within the Shimano system.
SRAM: Innovation Meets Performance
SRAM revolutionised the road bike world with wireless AXS technology. The electronic Red AXS and Force AXS rear derailleurs offer absolute shifting precision without cable clutter. The mechanical SRAM groupsets also impress with innovative technologies such as X-Range gearing. SRAM focuses on 12-speed and 13-speed systems that score with their wide range.
Mechanical vs. Electronic: Making the Right Choice
Mechanical rear derailleurs convince through simplicity, reliability and low maintenance requirements. They operate via shift cables and offer direct feedback when shifting. Ideal for everyone who values traditional technology.
Electronic rear derailleurs, on the other hand, offer the highest precision, adjustable shift characteristics and minimal effort. The battery-powered systems enable perfect gear changes even under load and often offer additional features such as smartphone connectivity.
Cassette Compatibility: 11-Speed, 12-Speed and 13-Speed
The number of gears largely determines the compatibility of your rear derailleur:
- 11-speed systems are proven and offer broad compatibility, especially with older wheelsets
- 12-speed drivetrains currently dominate the market and offer optimal balance between gear variety and compatibility
- 13-speed technology represents the latest in technology with the finest gear increments, but requires special components
- Important: Rear derailleur, cassette and shifter must come from the same manufacturer and support the identical number of gears.
UDH: Revolution for Gravel Bikes
The Universal Derailleur Hanger (UDH) is establishing itself as the new standard for modern gravel bikes. This universal derailleur hanger solution offers decisive advantages:
- Improved durability through more robust construction
- Universal compatibility between different manufacturers
- Optimised chainline for better shifting performance
- Future-proofing through cross-manufacturer standardisation
Frames with UDH-compatible derailleur hangers make it possible to mount modern SRAM AXS rear derailleurs without being dependent on proprietary derailleur hangers.
Choosing the Right Rear Derailleur
When selecting your new rear derailleur, you should consider the following factors:
- Application: Road bike for the road or gravel for mixed terrain
- Cassette size: Maximum number of teeth and desired gear range
- Groupset: Compatibility with existing components
- Budget: Mechanical systems are cheaper, electronic offer more performance
- Maintenance requirements: Mechanical systems are easier to maintain
