SRAM X4 SX4 Rear Derailleur Pulley Kit

The SRAM X4 SX4 rear derailleur jockey wheel kit is a replacement part for the rear derailleur consisting of two parts, the tension and guide jockey wheels. It is intended for anyone who needs to replace worn jockey wheels during drivetrain maintenance.

The kit is compatible with X.5 (2008-2010), X.4, SX5, SX4 and 24- and 21-speed Dual Drive derailleurs. Before ordering, check your rear derailleur model: the stated compatibility applies only to these groupsets. To confirm the match, compare the model list with the code printed on your derailleur. The parts are made from aluminium, alloy, steel and plastic, are black, and have a height of 50 mm.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
