CNC-machined from titanium and built around Grade 3 Silicon Nitride ceramic balls running in hardened steel races, these pulleys are engineered to reduce frictional drag to a figure that approaches negligible. Titanium construction is designed to last approximately four times longer than the aluminum alloy pulleys it replaces — which itself outlasts the standard plastic.\u003c\/p\u003e\n\n\u003cp\u003eThe ceramic balls CeramicSpeed uses are produced to tight tolerances, with the manufacturer citing 400% smoother surfaces and 128% greater hardness compared to standard steel balls. The bearings are assembled in dust-free clean rooms and intended to outlast conventional sealed races by three to five times the normal service life. Installation requires only a 2.5mm Allen key — the upper and lower pulleys are not interchangeable, so orientation matters, and the original SRAM spacers should be retained and reused. Periodic maintenance is straightforward: a drop of thin oil at the seal edge after chain lubing or a wash keeps drag at its lowest.\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\u003eCompatible with: SRAM 1x11 rear derailleurs \u003c!-- VERIFY: confirm exact derailleur compatibility beyond XX1 and X01 --\u003e\n\u003c\/li\u003e\n  \u003cli\u003ePulley material: CNC-machined titanium\u003c\/li\u003e\n  \u003cli\u003eBearing balls: Grade 3 Silicon Nitride ceramic\u003c\/li\u003e\n  \u003cli\u003eRaces: Hardened steel, clean-room assembled\u003c\/li\u003e\n  \u003cli\u003eInstallation tool: 2.5mm Allen key\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"CeramicSpeed","offers":[{"title":"Default Title","offer_id":43705649594412,"sku":"101713","price":456.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/ceramicspeed-ceramic-titanium-derailleur-pulleys-sram-1-11-speed-2326107.jpg?v=1771301707","url":"https:\/\/ricycles.com\/products\/ceramicspeed-ceramic-titanium-derailleur-pulleys-sram-1-11-speed","provider":"RA Cycles","version":"1.0","type":"link"}
