6 Rear Derailleurs
Buying advice for: Bicycle gear shifting: Rear Derailleur
Types of rear derailleur
The most common types of derailleur are the derailleur derailleur and the hub derailleur. The derailleur is particularly widespread on racing bikes and mountain bikes. It works by guiding the chain over various chainrings and sprockets, allowing the gears to be changed. A hub derailleur, on the other hand, is integrated into the rear wheel hub and is often used on city and trekking bikes. Hub gears are less susceptible to dirt and require less maintenance than derailleur gears, but generally offer fewer gears.
Rear derailleur brands
Well-known derailleur brands are Shimano, SRAM and Campagnolo. Shimano, a Japanese company, is the market leader and offers a wide range of rear derailleurs for all types of bicycles. SRAM, an American manufacturer, is particularly strong in the mountain bike sector and is known for its innovative 1x drivetrain systems, which only use one front chainring. Campagnolo from Italy enjoys an excellent reputation in the road bike segment and is known for its precise workmanship and durability. These brands set standards in terms of shifting performance and reliability.
Materials and workmanship
The materials and workmanship of a rear derailleur are decisive for its performance and durability. High-quality rear derailleurs are often made of aluminium, stainless steel or carbon. Aluminium offers a good weight/strength ratio and is used in many mid to upper price ranges. Carbon is very light and is used in high-end rear derailleurs to minimise the overall weight of the bike. Stainless steel is often used for derailleur cages as it is particularly robust and durable.
Technical features
The technical features of a rear derailleur include the number of gear steps, capacity and shifting precision. Modern rear derailleurs offer up to 12 gears, which enables fine gradation and adaptation to different terrains. Electronic rear derailleurs such as Shimano Di2 or SRAM eTap offer particularly precise and fast gear changes, as they are controlled at the touch of a button and not mechanically. The capacity of a rear derailleur describes how many teeth it can move in total, which is important for compatibility with different cassettes and chainrings. High shifting precision and speed are crucial for a smooth and efficient riding experience.
