Rear Derailleurs & Parts

Bicycle rear derailleurs and replacement parts for road, MTB, gravel, cyclocross, trekking and e-bike bicycles. The rear derailleur is one of the key components of a modern drivetrain, responsible for precise and reliable chain movement across the cassette.

Our range includes rear derailleurs and replacement parts from leading manufacturers such as Shimano, SRAM, Campagnolo, FSA, MicroSHIFT and SunRace. Solutions are available for mechanical and electronic shifting systems and a wide range of drivetrain speeds.

The category includes derailleur pulleys, pulley cages, jockey wheels, springs, bolts, fixing hardware, clutch components, adjustment screws and other service parts. For electronic drivetrains, compatible Shimano Di2 and SRAM AXS derailleurs and related components are also available.

The selection covers systems including Shimano 105, Ultegra, Dura-Ace, GRX, Deore, SLX, XT and XTR, SRAM Rival, Force, Red, Apex, GX, X01 and XX1, as well as various Campagnolo road and gravel groupsets.

When selecting a rear derailleur, it is important to check the number of speeds, shifting system, maximum cassette size, derailleur cage length, mounting standard and compatibility with the specific drivetrain.
