Designed to adapt a PF30 frame shell to a 24mm spindle crank, it uses Grade 3 Silicon Nitride ceramic ball bearings pressed into hardened steel races, delivering measurably lower rolling resistance than standard steel bearings alongside improved longevity.\u003c\/p\u003e\n\n\u003cp\u003eThe PF30 standard uses a 46mm diameter shell housing — wider than the traditional BB30 — which allows the bearings to seat inside removable aluminum cups rather than requiring snap rings. CeramicSpeed presses the bearings into machined aluminum cups in Denmark, resulting in a precisely assembled unit that installs cleanly into your frame and stays there. The ceramic balls require less lubrication than steel and resist corrosion, which means longer service intervals and consistent performance deep into a season.\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\u003e\n\u003cstrong\u003eBottom bracket standard:\u003c\/strong\u003e PF30 (46mm shell diameter, 68mm shell width)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle compatibility:\u003c\/strong\u003e 24mm — fits Shimano road cranks\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing type:\u003c\/strong\u003e Grade 3 Silicon Nitride ceramic balls in hardened steel races\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCup material:\u003c\/strong\u003e Machined aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable finishes:\u003c\/strong\u003e Black, Red\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"CeramicSpeed","offers":[{"title":"Black","offer_id":43509499887660,"sku":"101379","price":284.25,"currency_code":"USD","in_stock":true},{"title":"Red","offer_id":43509499920428,"sku":"101381","price":284.25,"currency_code":"USD","in_stock":true}],"url":"https:\/\/ricycles.com\/products\/ceramicspeed-ceramic-race-bottom-bracket-pf30-to-24mm-shimano","provider":"RA Cycles","version":"1.0","type":"link"}
