Rotor/CeramicSpeed PressFit 4630 bottom bracket.

This is a special one - a combination of CeramicSpeed bearings pressed into a Rotor PressFit 4630 shell and greased with CeramicSpeed long-life grease.

The bearings: hand-built in Denmark these grade 3 Silicon Nitride ceramic bearings are super smooth and when matched with the hardened steel raceways the bearings provide an ultra-smooth run. CeramicSpeed is well known for optimizing watt-efficiency and their quality build bearings deliver strong, lightweight, and highly precise ceramic power.

The shell: the PressfFit 4630 is designed with the Rotor Universal Bottom Bracket concept to ensure easy bottom bracket/crank compatibility. The bottom bracket is designed for when installing a PF30, BBright, or BB386evo crankset into the bike frame. It is made for frames with a bottom bracket shell of 46mm.

Note: outer dust caps are not included.

The product is as good as new, though they may have been mounted but never actually ridden.
