Shimano Ultegra Rear Derailleur Pulley

Yes, this set is specifically engineered for 11-speed drivetrain systems, ensuring seamless integration with your existing setup.

Absolutely. These pulleys are fully compatible with both the Ultegra 6800-series and the newer R8000-series rear derailleurs.

These are genuine Shimano components, meaning they are built to the exact tolerances required for your derailleur's geometry. Using official parts ensures the refined tooth profile engages your chain precisely, maintaining the smooth shifting performance you expect from the Ultegra group.

You should replace your pulleys if the teeth have become sharp or pointed, or if you notice excessive lateral play in the pulley wheels. Worn pulleys can lead to noisy shifting and decreased drivetrain efficiency.

Yes, this kit includes both the guide pulley (upper) and the tension pulley (lower) required to fully refresh your rear derailleur.
