CeramicSpeed PF4130 Road and MTB Bottom Bracket

CeramicSpeed PF4130 Road and MTB Bottom Bracket

The CeramicSpeed PF4130 Road and MTB Bottom Bracket is made for 41 mm diameter shells that are 86.5 mm wide and works with cranks that have a 30 mm spindle. So if you have a BB86 frame and want to install a 386EVO or standard 30 mm crank (ROTOR, Easton, etc.), this is the bottom bracket you need!

The CeramicSpeed Difference

CeramicSpeed Standard Bearings last at least three times longer than other bearings. That’s thanks to hardened-steel races and CeramicSpeed Balls that are 100% smoother and 15% harder than other ceramic bottom brackets. CeramicSpeed bearings have a frictional drag of 0.3-0.4 watts per set, which represents an average 75% drag reduction compared to other BBs.

Coated Finish Option

The unique coating formula is a metallic layer that covers the bearing races and makes them 75% harder than steel. Thanks to this, they are highly resistant to corrosion and the coating provides an even lower friction than the standard bearings. Even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible with the coated version. CeramicSpeed coated products are covered by a lifetime warranty.
