+Eduardo García Gutiérrez only with the CULT bearings, which in any case come stock in some of their wheel sets only. CeramicSpeed is a 3rd party supplier of, well, ceramic bearings. These shown are not the original Campagnolo ones.
methought ceramic bearing didn't need (much) "grease" at all, friction wise, to perform? Also.....how often do you suggest (or how many km's...) having to clean/service these bearings? @CeramicSpeed .
+al karg After 5-10.000 km or at least once every year, even CeramicSpeed bearings need to undergo maintenance. That is to ensure the same optimal performance and to increase the lifetime of your CeramicSpeed bearings. Compared to other commonly used bearings on the market, the need for maintenance interventions on CeramicSpeed bearings is reduced. Nevertheless, all bearings need maintenance and greasing from time to time.
Thank you very mcuh for the video. Really appreciated. What is the part number of these ceramic bearings, I wanted to fit a pair in the 2009 version of theFulcrum racing 1
when i try to remove the screw over the bearings adjuster, the one that will remove is the opposite one, so i cant remove the bearing adjustment screw. any suggestion?
I have the same problem. I filed flats at a very careful and parallel 14 mm width in the opposite side of the axle to hold it while removing the part concentric with the bearing adjuster.
The cult bearings races and balls are so hard they don't need grease, oiling is enough. All the other bearings need grease. In the old days race wheels were oiled and maintained after a short period. For the lowest friction. Grease creates more friction than oil, but will protect better against time and elements like water.
Fulcrum wheels are made by Campagnolo, they're one of the best wheel makers in the world in case you were wondering, in any case my Fulcrum Zeros are amazingly good, why don't you like them?
Hi Tim, thank you for your question. It is a common misconception that 'hard' ceramic balls will destroy 'soft' steel. If the balls were not smooth and evenly spherical, there could be durability issues in this combination. However, with the precise quality of CeramicSpeed balls, the hardness of the ceramic balls enables the surface to remain smooth and overall shape to remain perfectly spherical, leaving no way for the balls to damage the steel (two smooth surfaces rolling together).
Hi Tim, while this is something we would expect within our industrial division working with larger bearings or heavier loading, we would not expect much of a smoothing effect within the loads bicycle bearings regularly experience.
much better than the fulcrum videos
I learned from a very easy-to-understand video.
It ’s a very good job !
Brilliant video, thanks
Hello CeramicSpeed ! Campagnolo says thats not grease lubrication, only oil film, isnt it?

Funny seeing the nutramino shaker that just got a new sticker on the side..
Helpfull thx

It should be FULCRUM BEARING KIT RS-100 FOR WHEELS WITH OS HUBS FROM MODEL 2008

hello nice video thanks ,but I checked campy site and they say to use synthetic oil not grease for the CULT bearing, any comments?

its USB or CULT bearings?
Name Grease for Freehub???)
do you have any dealers in the Philippines?
LOL! All the videos about Fulcrum wheels are repair videos. I bought a pair of Fulcrum wheels, and I fucking hate them.
ya mate, i was debating about getting a pair of fulcrum wheels this past summer, but I saw lots of complaints about the hubs, so decided against it.
thechosendude Yeah buddy definitely do NOT buy from Fulcrum. Worst wheel set I have ever had. Basically ruined my entire summer of riding.

Overpriced and unnecessary
what happens to metal races with hard ceramic balls?

@@CeramicSpeed is it true they have a smoothing effect?
a smoothing effect unlike steal?
