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

The CeramicSpeed Ceramic Race Coated Bottom Bracket EVO386 to 30mm solves a specific problem cleanly: getting Campagnolo Over-Torque cranks — with their 30mm spindle — into a BB386 EVO shell. The BB386 EVO standard pairs an 86.5mm-wide shell with a 46mm inner diameter, combining the width advantage of wider press-fit standards with the rigidity of a larger-diameter spindle interface. CeramicSpeed's aluminum cups press into that shell and carry Grade 3 Silicon Nitride ceramic balls — a bearing specification that targets a measurable reduction in rotational friction compared to standard steel.

Those Grade 3 Silicon Nitride balls are installed into hardened steel races in dust-free clean rooms and checked before final assembly. CeramicSpeed's own testing claims the balls are 400% smoother and 128% harder than standard steel balls, with bearing service life designed to run three to five times longer. The aluminum cups are machined by Rotor in Spain; the bearings are pressed in Denmark. Available in Black or Red to match your build.
