CeramicSpeed OSPW Pulley Wheel System Shimano 9100/9150 8000 SS/8050 SS - Coated Races Alloy Pulley Carbon Cage Red

When every watt counts and every shift matters, this oversized pulley system helps you glide through gears with less effort. By reducing friction in the rear derailleur, it translates to crisper shifts, better acceleration, and a more confident ride on demanding routes. It’s a premium upgrade for riders who measure performance by feel, not just speed.

Who is this for?

Ideal for performance-minded cyclists who ride high-end Shimano Dura-Ace setups and seek maximum efficiency on long climbs, fast descents, and race-day efforts. If you value precise, friction-free shifting and a cleaner, more responsive drivetrain, this system is designed for you.

Each item is professionally packed and shipped next day. Select in-store pick-up at checkout and visit us if you are local!
