Designed to mate a PF30 shell with a GXP crankset — the SRAM-specific spindle standard with a 24mm drive-side and 22.5mm non-drive-side diameter — it uses Grade 3 Silicon Nitride ceramic ball bearings pressed into hardened steel races for a measurable reduction in rolling resistance over conventional steel bearings.\u003c\/p\u003e\n\n\u003cp\u003eThe aluminum cups and sleeves are machined by Rotor in Spain, then the bearings are pressed into place at CeramicSpeed's facility in Denmark. The PF30 format uses a 46mm shell diameter — wider than BB30 — which allows the cups to press directly into the frame without snap rings, keeping the assembly clean and serviceable. \u003cstrong\u003eLower friction and longer service intervals\u003c\/strong\u003e are the practical result of the ceramic bearing design, which is why this standard has found its way into professional racing at the highest levels.\u003c\/p\u003e\n\n\u003ch3\u003eCeramicSpeed Ceramic Race Bottom Bracket Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003eCompatibility: PF30 frame shell with GXP (SRAM\/Quarq) cranks\u003c\/li\u003e\n  \u003cli\u003eBearing type: Grade 3 Silicon Nitride ceramic balls in hardened steel races\u003c\/li\u003e\n  \u003cli\u003eShell diameter: 46mm (PF30 standard)\u003c\/li\u003e\n  \u003cli\u003eShell width: 68mm\u003c\/li\u003e\n  \u003cli\u003eCups and sleeves: Machined aluminum\u003c\/li\u003e\n  \u003cli\u003eAvailable in Black and Red\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"CeramicSpeed","offers":[{"title":"Black","offer_id":43509500641324,"sku":"101395","price":284.25,"currency_code":"USD","in_stock":true},{"title":"Red","offer_id":43509500674092,"sku":"101397","price":284.25,"currency_code":"USD","in_stock":true}],"url":"https:\/\/ricycles.com\/products\/ceramicspeed-ceramic-race-bottom-bracket-pf30-to-gxp-sram","provider":"RA Cycles","version":"1.0","type":"link"}
