CeramicSpeed Ceramic Titanium Derailleur Pulleys - Campagnolo 11 Speed

Derailleur pulleys are a small upgrade with a measurable return — and the CeramicSpeed Ceramic Titanium Derailleur Pulleys for Campagnolo 11 Speed represent the higher tier of that investment. The pulley bodies are CNC-machined titanium, with cutouts beneath the teeth for both weight reduction and debris clearance. Pressed into each pulley are CeramicSpeed's hybrid ceramic bearings, where Grade 3 Silicon Nitride balls run in hardened steel races — assembled in dust-free clean rooms and inspected before leaving.

The ceramic balls are designed to be significantly smoother, harder, and lighter than standard steel balls, with CeramicSpeed claiming up to 400% smoother surface finish and 128% greater hardness. The titanium pulley bodies are intended to outlast aluminium alternatives by a considerable margin, and the ceramic bearings are designed for a service life three to five times longer than conventional sealed units. Installation requires only a 3mm hex key — the upper pulley is slightly narrower to reduce the need for precise centering.
