The OverTorque spindle runs 30mm in diameter as a single-piece design — stiffer and lighter than earlier two-piece 25mm spindle configurations — and CeramicSpeed's Grade 3 Silicon Nitride ceramic balls are the right bearing for it. These bearings are pressed into aluminium cups inside machined aluminium sleeves, then assembled in Denmark.\u003c\/p\u003e\n\n\u003cp\u003eThe PF30 standard uses a 46mm shell bore — larger than a standard BB30 shell — which allows the bearings to sit inside pressed cups rather than directly against the shell. \u003cstrong\u003eCeramicSpeed's ceramic balls\u003c\/strong\u003e are harder and smoother than steel, which means lower friction under load and extended service intervals compared to conventional steel bearings.
