Bike Derailleurs

Explore Our Bike Derailleurs

Decathlon provides a durable and high-quality range of bike derailleurs, derailleur cables and derailleur guards to meet the varying needs and experience levels of cyclists. To complete your bike transmission system, our derailleurs adapt to different diameters, frames, brands, and bike sizes to ensure a smooth and precise transmission.

Front or Rear: Choosing the Right Derailleur

Essential to the proper functioning of your bike, bike derailleurs can be installed in different locations. The rear derailleur allows you to change the chain's gears from one sprocket to another. The front derailleur is mounted on the frame and lets you change the chain's gears between the chainrings on the crankset.

To effectively complete your transmission system, we also offer cable and housing sets for bike derailleurs, suitable for all types of models. Enjoy all our cycling gear, including our derailleur guards, derailleur hanger replacements, and cable end caps for your bike.
