CeramicSpeed OSPW Pulley Wheel System Campagnolo Derailleurs - Alloy Pulley Carbon Cage BLK

Imagine shifting with zero hesitation on long climbs; this oversize pulley system optimizes your rear derailleur, cutting friction and delivering crisper, more efficient power transfer. The CeramicSpeed design uses extremely low-friction bearings to smooth chain movement, while a 13-tooth upper and 19-tooth lower aluminum pulley setup reduces energy loss over every pedal stroke. The rugged polyamide and carbon fiber cage keeps weight down without sacrificing durability, so you get a responsive ride ride ride that lasts season after season.

Who is this for?

Riders who want enhanced shifting precision on Campagnolo-equipped bikes—especially those using Chorus or other Campagnolo derailleurs up to a 32t cassette. If you value reduced drivetrain resistance, longer chain life, and a noticeably more immediate response when you roll on the pedals, this upgrade is 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!
