The 14-tooth wide-narrow pulleys run on CeramicSpeed's coated hybrid ceramic bearings — Grade 3 Silicon Nitride balls seated in races finished with a metallic alloy coating three microns thick and 75% harder than standard hardened steel races.\u003c\/p\u003e\n\n\u003cp\u003eThat coating is the defining detail here. Where standard ceramic bearings are already measurably faster than steel, the coated races add a smoother, longer-lasting running surface — reducing friction further and extending service intervals. CeramicSpeed's own testing puts the efficiency gain of their Eagle pulleys over stock at 34.4%. The wide-narrow tooth profile requires correct initial alignment with the chain, but once set, it holds engagement reliably and \u003cstrong\u003ereduces mechanical wear\u003c\/strong\u003e across the full cassette range.
