SRAM X01 X1 CX1 X-Sync Derailleur Pulley Kit

The SRAM X01 X1 CX1 X-Sync jockey wheel kit is a replacement for the 11-speed rear derailleur in the X01, X1, CX1 and RED eTap series, for use when the original jockey wheels are worn. It guides the chain correctly and maintains precise shifting.

The kit for X01, X1 and CX1 is made of black plastic, while the kit for RED eTap is ceramic. Before buying, check that your rear derailleur is compatible: X.01, X.01 HD, GX1 and CX1 for the plastic kit, RED eTap for the ceramic kit. The kit is designed for these drivetrains, so it should not be chosen solely by the groupset name.

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.
