Ceramic Bearings

What would be the reason to upgrade to ceramic bearings? Sorry for not being more specific but what do you gain with ceramic bearings over normal bearings?

Not being an expert on the matter, I have picked up a thing or two about ceramic bearings: From what I understand, the major gain you get with ceramic bearings is weight (steel ball bearings are heavier than their ceramic brethren). Also, ceramic balls can be made smoother than steel balls, thus "adding" to the function of the bearing i.e. reducing friction even more than you would get in a stell ball bearing. This, of course, in the end means that the wheel will spin with less friction.

The third thing is longevity. Ceramic bearings tend to experience less wear and tear than steel bearings. This may be due to the lesser amount of friction on the ceramic balls, but I'm not too sure on this... :-)

The drawback with ceramic bearings - from what I've heard - is that if you for some reason get dirt or grit in the bearing it will wear down faster than a steel bearing. Also, I've heard that if you get water in a ceramic bearing, it will reduce the functionality of the bearing, i.e. increase friction. Don't know how much water will affect steel bearings, though, but my guess is that ceramic bearings are a bit more sensitive in this regard.

That being said, I have wheels with both types of bearings and in my opinion, my wheel set with the ceramic set-up (DT-Swiss 190 hubs) is absolutely fantastic! I can really tell the difference from my "non-ceramic" wheels. They won't stop rolling for quite a while, even if I stop pedalling...! :-) And especially on descents, I can reach higher top speeds than with my other wheels.

I hope this somewhat answers your question... You can probably get more in-depth information and reviews on the Web if you look around a bit.

Ceramic bearings give you a very small advantage... maybe 1-3% and can last a little longer. That said, our stainless steel bearings are Japanese EZO bearings which are some of the best in the industry. Both are really good bearings and if you have to have the best... ceramic is the way to go.

Below are two articles. The first about our Ceramic Bearings... the second about our Stainless Steel Bearings.

Our Ceramic Bearings are actually a little bit heavier. About 1 gram. This is because they use 11 ball bearings instead of the 10 seen in the SS bearings.

Also, ceramic balls can be made smoother than steel balls, thus "adding" to the function of the bearing i.e. reducing friction even more than you would get in a stell ball bearing. This, of course, in the end means that the wheel will spin with less friction.

Yes. Also, with 11 ball bearings, each bearing has to be smaller compared to the 10 ball bearing in our SS bearings. Here is a quote from our blog about the smaller bearings...

"bearing manufacturers use ceramic balls with smaller diameters (shown below) which greatly reduces the influence of centrifugal force (ie. ball sliding and spinning caused by a gyratory moment). As a result, ceramic bearings show a reduction in temperature build up and an improvement when spinning at high speeds."


The third thing is longevity. Ceramic bearings tend to experience less wear and tear than steel bearings. This may be due to the lesser amount of friction on the ceramic balls, but I'm not too sure on this... :-)
