Buy rear derailleurs online – Precision for every riding situation
A high-quality rear derailleur ensures clean gear changes, reliable chain guidance and optimal power transmission. The range covers the common speed levels from 7-speed to 13-speed and offers both mechanical rear derailleurs with classic cable operation and modern electronic systems such as Shimano Di2 and SRAM AXS. Whether you are a road cyclist, mountain biker, gravel bike enthusiast or everyday rider, you will find the ideal rear derailleur for your riding style and area of use.
Rear derailleurs by area of use
For road bikes, rear derailleurs with short or medium cages and precise gearing are suitable, such as those offered by Shimano Ultegra, Dura-Ace or SRAM Force. In the mountain bike sector, long cages and Shadow Plus damping are used, for example on Shimano Deore, SLX or XT. For gravel bikes, versatile rear derailleurs with large capacity are ideal, covering wide gear ranges and varied terrain. E-bike riders benefit from robust rear derailleurs designed for higher torque that shift cleanly even under load.
Mechanical or electronic rear derailleurs?
Mechanical rear derailleurs impress with simple maintenance, low weight and an attractive price. Electronic rear derailleurs such as Shimano Di2 and SRAM AXS offer faster, more precise shifting and can be individually configured. Both variants have their merits – the choice depends on budget, desired comfort and the existing groupset. Retrofitting from mechanical to electronic is possible on many frames, but should be coordinated with a specialist workshop.
This category is aimed at all cyclists in Switzerland who want to replace, upgrade or build a new rear derailleur. Road cyclists will find high-precision lightweight rear derailleurs, mountain bikers rely on robust components with damping, and gravel bike riders choose versatile rear derailleurs for mixed terrain. Everyday cyclists and e-bike owners who value reliable shifting will also find what they need here.
Quality, compatibility and material
When purchasing a rear derailleur, it is worth looking at high-quality materials such as aluminium, carbon or steel alloys, which combine durability and low weight. Compatibility with the existing groupset, cassette and chain is also crucial – not every rear derailleur works with every shift lever. Careful coordination of all components guarantees a smooth shifting experience over many kilometres.
Frequently Asked Questions
What is a rear derailleur and what is its function?▾
A rear derailleur is a central component of the bicycle drivetrain. It sits at the rear dropout of the frame and moves the chain across the sprockets of the cassette to engage the desired gear. The function is controlled via the shift lever on the handlebar, which is connected to the rear derailleur by a Bowden cable or electronically.
What types of rear derailleurs are there?▾
There are mechanical rear derailleurs operated by a cable, and electronic rear derailleurs such as Shimano Di2 or SRAM AXS, which shift wirelessly or via cable. Additionally, a distinction is made between short, medium and long cage lengths – depending on the gear range and intended use on road bikes, mountain bikes or gravel bikes.
How do I find the right rear derailleur for my bike?▾
Compatibility depends on the groupset, the number of sprockets on the cassette and the capacity of the rear derailleur. Important factors are compatibility with the shift lever, the maximum tooth capacity and the mounting type. If in doubt, consult the manufacturer's specifications or coordinate with a specialist workshop in Switzerland.
What does the cage length mean on a rear derailleur?▾
The cage length determines how much chain tension the rear derailleur can accommodate. A short cage is suitable for road bike drivetrains with narrow gear ratios and a single chainring. A medium or long cage is required for wider gear ranges, multiple chainrings or mountain bike drivetrains with large cassettes to prevent the chain from sagging.
Can I install and adjust a rear derailleur myself?▾
Yes, with some technical skill and the right tools, a rear derailleur can be installed yourself. Correct adjustment of the limit screws, cable tension and alignment of the rear derailleur are important. Many manufacturers offer instructions and videos, and there are numerous specialist workshops in Switzerland that can assist if needed.
When should a rear derailleur be replaced?▾
Replacement is advisable when the rear derailleur is bent or damaged, shifting precision deteriorates despite adjustment, or an upgrade to a modern groupset is desired. After a crash that has affected the rear derailleur or derailleur hanger, inspection and if necessary replacement should also be carried out.
What are the differences between Shimano, SRAM and Campagnolo rear derailleurs?▾
Shimano relies on proven technology with broad compatibility and graduated series from Deore to Dura-Ace. SRAM is known for innovative solutions such as AXS wireless technology and the direct mount system. Campagnolo stands for Italian tradition, high-quality workmanship and precise shifting in the road bike sector. Each brand has its own strengths and its own ecosystem.
How do I properly care for and maintain my rear derailleur?▾
Regular cleaning with a damp cloth, lubricating the moving joints and checking the shift cable tension will maintain functionality. After riding in wet or dirty conditions, the rear derailleur should be cleaned promptly. A regular check of the limit screws and chain length helps prevent premature wear.
