Rear derailleurs for mountain bikes, road bikes and everyday bikes
Looking for a new rear derailleur for your bike? Has your rear derailleur become warped, worn or otherwise defective? Check out our selection from Shimano, Sram and more on this page. We have rear derailleurs ranging from the cheap series to Shimano Ultegra/XTR and Sram Eagle XX1 rear derailleur.
We focus on the best products at the best prices
The reason we focus primarily on Shimano and Sram rear derailleurs is because we know they can withstand high loads - and almost any type of weather. There can be many grams to be saved by upgrading from a cheap groupset to a more expensive one. In addition, the level of detail is also greater in the more expensive Shimano and Sram groupsets. If you're unsure which rear derailleur is right for your bike, feel free to contact us and we'll be happy to guide you.
Why a rear derailleur is one of the most important parts of your bike
A bicycle rear derailleur is an important component of your bike's drivetrain and gear system. The primary function of a rear derailleur is to change the position of the chain on the rear drive or cassette, resulting in different gear ratios. This serves several purposes:
-
Changing resistance: The rear derailleur allows the cyclist to adjust the resistance they encounter when pedaling. By changing gears, the cyclist can choose between lighter gears (lower resistance) that make it easier to pedal and accelerate, and heavier gears (higher resistance) that are more suitable for maintaining higher speeds.
-
Adapting to terrain: Bikes are used on different terrains and the rear derailleur allows you to adapt the gear ratios to the demands of the terrain. For example, you can choose lower gears to tackle steep inclines or higher gears to go fast on flat stretches.
-
Efficiency and comfort: By choosing the right gear ratios, cyclists can optimize their pedalling movements for a smooth and efficient ride. This reduces fatigue and increases comfort during long rides.
-
Handling varying conditions: The rear derailleur allows cyclists to adapt to changing weather conditions, wind and terrain, making it easier to handle different challenges on the road.
Rear derailleurs come in different types and levels of complexity depending on the type of bike and purpose. They can be mechanical or electronic and come in different speeds (e.g. 7-speed, 9-speed, 11-speed, etc.) depending on how many gears they can handle. Overall, the rear derailleur plays a crucial role in allowing cyclists to choose the optimal gear and achieve the desired performance during their rides.
