CeramicSpeed Ceramic Alloy Derailleur Pulleys - Shimano 12-speed 9250/8150/7150 Info
Derailleur pulleys are one of the most overlooked friction points in a drivetrain — the CeramicSpeed Ceramic Alloy Derailleur Pulleys for Shimano 12-speed 9250/8150/7150 address that directly. CeramicSpeed's ceramic bearings sit inside alloy pulley bodies, replacing the stock plastic-bodied wheels with something designed to spin with measurably less resistance and last considerably longer under load.
The kit covers both pulley positions and includes an aluminum spacer kit and oil, so installation is a straightforward bolt-on swap. If you're running Dura-Ace 9250, Ultegra 8150, or 105 7150, these are a direct-fit replacement — no modification required.
