CeramicSpeed Ceramic Race Bottom Bracket - EVO386 to 30mm (Campy OverTorque)

The CeramicSpeed Ceramic Race Bottom Bracket EVO386 to 30mm (Campy OverTorque) solves a specific fitment problem with precision hardware: it lets you run Campagnolo Over-Torque cranks — which use a 30mm spindle — in a BB386 EVO shell. The aluminum cups press into the 86.5mm-wide, 46mm-inner-diameter shell, and CeramicSpeed's Grade 3 Silicon Nitride ceramic balls do the rest.

Those ceramic balls are the reason riders seek out CeramicSpeed in the first place. Manufactured to a surface finish and roundness that far exceeds standard steel bearings, they're pressed into hardened steel races in dust-free clean rooms in Denmark — a process that produces genuinely lower frictional resistance and bearing life that CeramicSpeed rates at three to five times longer than conventional bearings. Available in Black or Red.
