CeramicSpeed PF4130 Bottom Bracket – Black

The pf4130 bottom bracket is press fit into 41mm diameter shells that are 86.5mm wide and mate most cranks with a 30mm spindle to that standard. If you have a bb86 frame and want to install a 386evo crank or rotor 30mm crank, this is the kit you need.

Ceramicspeed bearings are installed in cups. The standard bearing has ceramic cs balls and hardened-steel races. The coated bearing has the same balls running on hardened-steel races with a 3-micron thick metallic coating making the races harder and smoother, increasing service life and reducing friction.
