Derailleurs
Bicycle Derailleurs
Bicycle derailleurs are essential components of the transmission system that allow you to change gears by moving the chain between different cogs on the rear cassette or front chainrings. There are several reputable brands of derailleurs on the market, including Shimano, SRAM, and Campagnolo.
Shimano derailleurs offer a wide range of models suitable for both road and mountain bikes. They come in different series such as Tiagra, 105, Ultegra, and Dura Ace for road derailleurs, and Deore, SLX, XT, and XTR for mountain derailleurs. Shimano also offers high-performance electronic derailleurs like Di2.
SRAM is another renowned brand in the field of bicycle derailleurs. Their models include road derailleurs like Force and Red, as well as mountain derailleurs like NX Eagle, GX Eagle, and X01 Eagle. SRAM also offers wireless electronic derailleurs like eTap AXS.
Campagnolo is particularly known for its high-end road bike derailleurs. Their series include Chorus, Record, and Super Record, offering precise performance and high reliability.
How to Choose a Derailleur?
Choosing a derailleur depends on the type of bike and intended use. Road derailleurs are specifically designed for road bikes, while mountain derailleurs are tailored to the demands of mountain biking. Electronic derailleurs offer superior shifting precision and speed but come at a higher cost.
How to Adjust a Derailleur?
To adjust a derailleur, you need to adjust the high and low limit screws to limit its movement between cogs and ensure the chain remains tensioned. Regular cleaning of derailleurs is also important to maintain their proper function and extend their lifespan.
When a derailleur shows signs of wear, such as difficult gear shifts, faulty adjustment screws, or chain tension loss, it's generally necessary to replace it. Derailleur hangers, on the other hand, are essential parts that connect the derailleur to the frame and can be replaced if damaged.
How to Clean a Derailleur?
To keep your bike running smoothly, it's essential to regularly clean the drivetrain. Use a specific degreaser to remove dirt and debris. A toothbrush helps access hard-to-reach areas, while a flathead screwdriver removes oil deposits from jockey wheels. For a thorough cleaning, disassemble the derailleurs and soak them in a strong degreaser. Then, reinstall them on the bike. This way, your derailleurs will be like new, and your bike will be well-maintained.
Bicycle derailleurs play a crucial role in the operation and performance of the transmission. It's important to choose a derailleur that suits your bike type, consider the desired gear range, and ensure their regular maintenance for proper function.
