The result is a measurable reduction in drivetrain friction that you feel in the pedals on every ride.\u003c\/p\u003e\n\n\u003cp\u003eEach pulley runs 14 teeth with a narrow-wide tooth profile designed to engage SRAM Eagle 12-speed chain precisely. CeramicSpeed's own testing puts the efficiency gain at 34.4% over stock pulleys — a figure derived from their standard uncoated bearing configuration. The ceramic balls themselves are tested to be smoother, harder, and lighter than both standard steel and conventional ceramic alternatives, and they're assembled in dust-free clean rooms before a final quality check. Available in Black or Gold anodized finish.\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 SRAM Eagle 12-speed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth count:\u003c\/strong\u003e 14T narrow-wide\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\u003eBody material:\u003c\/strong\u003e Anodized aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish options:\u003c\/strong\u003e Black, Gold\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"CeramicSpeed","offers":[{"title":"Black","offer_id":43509471903788,"sku":"103343","price":399.0,"currency_code":"USD","in_stock":true},{"title":"Gold","offer_id":43509471936556,"sku":"103344","price":399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/ceramicspeed-ceramic-alloy-derailleur-pulleys-sram-eagle-14-12-speed-6105284.jpg?v=1771301711","url":"https:\/\/ricycles.com\/products\/ceramicspeed-ceramic-alloy-derailleur-pulleys-sram-eagle-14-12-speed","provider":"RA Cycles","version":"1.0","type":"link"}
