Ceramicspeed PF4130 Coated bottom bracket cups

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.
