Bicycle Rear Derailleur Jockey Wheel - Narrow Wide 10T/12T/14T For Shimano

Keep your bike's shifting smooth and crisp with a new jockey wheel for your rear derailleur.

This is a single, narrow-wide jockey wheel (also called a pulley) that's compatible with many Shimano derailleurs.

You can choose the tooth count that fits your setup: 10T, 12T, or 14T.

The narrow-wide tooth profile helps keep the chain in place, especially on 1x drivetrains.

It's a simple, inexpensive replacement part that can make a big difference in shifting performance.

It's a brand new, unbranded part made in China.

If your current pulley is worn or chipped, swap it out.
