The bottom brackets from the Danish company CeramicSpeed represent the absolute high-end solution for all racing drivers who place the highest value on lowest friction with best power transmission. This makes you faster and more effective with the same effort. The CeramicSpeed-SpeedBalls balls are 15% harder than those of the competition and can absorb significantly more forces. They also have an incredibly smooth surface, thereby reducing rolling resistance to a minimum. 

What is  Coated?

The coated products are covered by a lifetime warranty. 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 our standard bearings. Even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible if you choose the coated version.
