A good MTB derailleur is essential for anyone looking to get the most out of their mountain bike, whether you're tackling technical climbs or speeding down descents.

What is an MTB Derailleur?

An MTB derailleur is a bicycle component that moves the chain from one gear to another, allowing you to shift between gears. There are two types of derailleurs: the front derailleur, which shifts the chain over the front chainrings, and the rear derailleur, which does so at the back on the cassette. Shifting is particularly important on mountain bikes as you often ride over rough terrain and need to switch gears quickly. A malfunctioning derailleur can cause delays, noise, or even damage to your chain or cassette. Therefore, a derailleur must be strong, precise, and durable.
 

Different MTB Derailleurs

There are many types of MTB derailleurs, each with its own function or application. Together, they ensure smooth shifting on any terrain.
•    MTB Rear Derailleur
Moves the chain over the rear gears. Important for precise shifting under load.
•    MTB Front Derailleur
Guides the chain over the front chainrings. Less commonly used in modern 1x drivetrains.
•    MTB Chain Guides
Keeps the chain in place on rough terrain. Especially useful in 1x drivetrains without a front derailleur.
 

Different Derailleur Parts:

•    MTB Derailleur Pulleys - Small wheels in the rear derailleur that guide the chain. They wear over time and can be replaced individually.
•    MTB Derailleur Pads - Mounting points on the frame. A removable pad prevents damage to the frame in case of a fall.
•    MTB Rear Derailleur Protectors - A metal bracket that protects the derailleur from impacts or falls.
•    MTB Shift Cables - Connects the shifter to the derailleur. Replace in time to maintain smooth shifting.
•    MTB Rear Derailleur Parts - Think of spare pulleys, springs, or mounting screws.
•    MTB Front Derailleur Parts - Brackets, bolts, or plates for mounting and adjustment.

MTB derailleurs are sturdier than those on road bikes or city bikes. They can better withstand mud, impacts, and shocks. There are also electronic derailleurs that shift with a motor. They are precise but more expensive and sensitive to dirt or damage.
 

What to Consider When Buying MTB Derailleurs?

Pay attention to the following specifications when choosing a derailleur:
•    Drive Type: 1x, 2x, or 3x front chainrings. Not every derailleur fits every system.
•    Capacity: Indicates how much difference in gear size the derailleur can handle between the smallest and largest cog of your cassette.
•    Mounting: Not every derailleur fits every frame. Check the attachment.
•    Compatibility: Not all parts fit every brand or model. Shimano and Sram are often not interchangeable.
•    Material: Aluminum is light and strong. Plastic parts are cheaper but wear out faster.
•    Spring Tension: Determines how tight the chain stays. Important for rough terrain.
•    Cage Length: Long, medium, or short. Depending on the cassette and chain length.

Maintenance is simple but important. Clean the derailleur with a cloth and a bit of degreaser. Then lightly lubricate with chain oil. Worn pulleys can be replaced by yourself. Cables and pads too. Regularly check for play or bent parts.
 

The Best Brands for MTB Derailleurs

•    Shimano: Reliable, affordable, and easily available. Popular on both entry-level and high-end MTBs.
•    Sram: Lightweight, precise shifting, and often used on modern 1x systems. Slightly more expensive but very robust.
•    SunRace: Good price-quality ratio. Less known, but a solid alternative to Shimano.
•    Marwi/Union: Offer parts such as derailleur pulleys and pads. Good for replacement or maintenance.

Shimano is ideal for those looking for a solid derailleur that is easy to adjust. Sram is perfect for enthusiastic riders who want quick response. SunRace is interesting as a budget option. Marwi is handy for those needing spare parts.

Frequently Asked Questions About MTB Derailleurs

Which MTB derailleur fits my bike?

Look at the number of gears and the size of your cassette. Also, check if your frame is suitable for the type of mounting.
 

When should I replace my derailleur?

When there is play, wear, or poor shifting. Also, after a fall, the derailleur may be bent.
 

How do I adjust my MTB derailleur?

Use the adjustment screws to align the derailleur properly. Pay attention to the limit screws and the tension of the cable.
 

What is the difference between a long and short cage?

A long cage is suitable for large cassettes and multiple front chainrings. A short cage is lighter and faster in 1x systems.
 

Can I replace my derailleur myself?

Yes. With a Phillips screwdriver, Allen key, and some patience, you can get quite far. Pay attention to proper adjustment after installation.
