Bicycle Rear Derailleur Jockey Wheel – 11T / 12T / 13T / 14T Bearing Pulley
Keep your drivetrain shifting smoothly with this precision-engineered rear derailleur jockey wheel. Compatible with 9, 10, 11, and 12-speed drivetrains, this POM bearing pulley roller is an essential repair and upgrade component for road bikes, mountain bikes, and general bicycles. Made in Mainland China.
Why Upgrade Your Jockey Wheel?
A worn or damaged derailleur pulley causes poor shifting, chain skip, and unnecessary drivetrain wear. Swapping in a fresh, sealed-bearing jockey wheel restores crisp, accurate gear changes and extends the life of your chain and cassette — all at a fraction of the cost of a full derailleur replacement.
