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.\u003c\/p\u003e\n\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch3\u003eCeramicSpeed Ceramic Titanium Derailleur Pulleys Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e All Campagnolo 11-speed derailleurs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePulley material:\u003c\/strong\u003e CNC-machined titanium with under-tooth cutouts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing type:\u003c\/strong\u003e Hybrid ceramic — Grade 3 Silicon Nitride balls in hardened steel races\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAssembly:\u003c\/strong\u003e Dust-free clean room construction with pre-assembly inspection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e 3mm hex key, upper and lower pulleys included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"CeramicSpeed","offers":[{"title":"Default Title","offer_id":43705649201196,"sku":"101710","price":351.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/ceramicspeed-ceramic-titanium-derailleur-pulleys-campagnolo-11-speed-3776993.jpg?v=1771301707","url":"https:\/\/ricycles.com\/products\/ceramicspeed-ceramic-titanium-derailleur-pulleys-campagnolo-11-speed","provider":"RA Cycles","version":"1.0","type":"link"}
