CeramicSpeed Ceramic Race Coated Bottom Bracket - PF30 to 30mm (Campy OverTorque)

The CeramicSpeed Ceramic Race Coated Bottom Bracket PF30 to 30mm is built specifically for Campagnolo OverTorque cranks running in a PF30 shell — a pairing that demands precise tolerances and bearings that can hold up to the torsional loads of a stiff, large-diameter spindle. CeramicSpeed uses Grade 3 Silicon Nitride ceramic balls pressed into coated steel races, delivering measurably lower friction and greater durability than conventional steel bearings. The coated race treatment adds a hardened surface layer designed to resist wear and extend service intervals.

The PF30 standard uses a 46mm shell diameter — wider than the original BB30 spec — which allows bearings to sit inside pressed aluminum cups rather than directly against the shell. That design reduces the risk of creaking and simplifies installation and removal. CeramicSpeed machines their cups to exacting tolerances, and the bearings are pressed in-house in Denmark to ensure consistent preload and alignment. Available in Black or Red anodized finish.
