If you're running a 10-speed SRAM road derailleur — Force, Rival, or Apex from the '07 through '13 era — and the jockey wheels are showing wear, chain slap, or bearing drag, this is the OEM replacement kit. SRAM's 10-Speed Rear Derailleur Pulley Set includes a pair of original equipment upper and lower rear derailleur pulleys with bearing plates featuring stainless steel sealed cartridge bearings, and it's compatible with SRAM Force, Rival, and Apex. It's the same pulley kit that shipped on the derailleurs from the factory, so shift feel returns to spec once they're installed.

The set arrives as a complete pair. Upper pulley (guide) and lower pulley (tension) are different — the lower pulley is the larger of the two and needs to go in the correct position on the cage, otherwise chain wrap and shift timing get thrown off. Both wheels ride on sealed cartridge bearings rather than bushings, which is what keeps them spinning smoothly through wet rides and road grit without the notchy feel that develops as bushings wear out.

Compatibility is limited to 10-speed SRAM road drivetrains. This kit does not fit 11-speed Force 22, Rival 22, or eTap groupsets, and it's not intended for SRAM's mountain derailleurs or the current AXS road platform. If you're not sure which generation of derailleur you have, the part number stamped on the derailleur cage or the original spec sheet from the bike will confirm it. For a 10-speed Force, Rival, or Apex rear derailleur, this is the direct-fit replacement.... Read More
