CeramicSpeed Ceramic Alloy Derailleur Pulleys - Campagnolo 11 Speed

Your derailleur pulleys are the fastest-spinning components on your bike, which makes them one of the most logical places to reduce drivetrain friction. The CeramicSpeed Ceramic Alloy Derailleur Pulleys for Campagnolo 11-Speed replace your stock pulleys with CNC-machined aluminum bodies and hybrid ceramic bearings — designed to spin with significantly less resistance than standard plastic or steel-bearing alternatives.

The ceramic balls used are Grade 3 Silicon Nitride, installed into hardened steel races in dust-free clean rooms. CeramicSpeed's hybrid ceramic construction is designed to last three to five times longer than conventional sealed bearings, and the machined aluminum bodies — with cut-outs beneath the teeth for both weight reduction and mud clearance — are built to outlast plastic pulleys by a considerable margin. Installation requires nothing more than a 3mm Allen key, and the pulleys are designed to fit all 11-speed Campagnolo rear derailleurs.
