The cutouts beneath the teeth shed weight and help clear debris, while the machined aluminum construction is built to outlast plastic pulley bodies by a significant margin.\u003c\/p\u003e\n\n\u003cp\u003eAt the core of the design are Grade 3 Silicon Nitride ceramic balls pressed into hardened steel races. CeramicSpeed manufactures these in dust-free clean rooms and inspects them before final assembly. The result is a bearing designed to last three to five times longer than conventional sealed bearings — and one that runs measurably freer under load. Installing them requires only a 2.5mm hex key; retain the spacers from your existing SRAM pulleys and orient the logo facing outward. Available in black or red.\u003c\/p\u003e\n\n\u003ch3\u003eCeramicSpeed Ceramic Alloy 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 SRAM 11-speed derailleurs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePulley material:\u003c\/strong\u003e CNC-machined aluminum with tooth cutouts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing type:\u003c\/strong\u003e Hybrid ceramic — Grade 3 Silicon Nitride balls, hardened steel races\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing service life:\u003c\/strong\u003e Designed to last 3–5x longer than standard sealed bearings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation tool:\u003c\/strong\u003e 2.5mm hex key\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"CeramicSpeed","offers":[{"title":"Black","offer_id":43509470625836,"sku":"101699","price":201.75,"currency_code":"USD","in_stock":true},{"title":"Red","offer_id":43509470658604,"sku":"101700","price":201.75,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/ceramicspeed-ceramic-alloy-derailleur-pulleys-sram-11-speed-9034393.jpg?v=1771301711","url":"https:\/\/ricycles.com\/products\/ceramicspeed-ceramic-alloy-derailleur-pulleys-sram-11-speed","provider":"RA Cycles","version":"1.0","type":"link"}
