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

Small inefficiencies in your drivetrain add up over a ride, draining watts and sapping cadence. The CeramicSpeed OSPW System uses oversized pulleys and ultra-low-friction bearings to minimize drag in the rear derailleur. The result is smoother shifts, reduced wear on your chain and cassette, and a crisper, more confident ride on climbs and fast descents.

Who is this for?

This upgrade is ideal for serious road riders and enthusiasts who demand peak drivetrain performance from their 11-speed Shimano setup. If you ride a Dura-Ace R9150-equipped bike and want crisper shifts, reduced drag, and a more consistent cadence on long climbs or fast-paced group rides, this is for you. It’s also a smart choice for riders seeking quiet operation and reliable performance under race-day or endurance-event conditions.

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