Hi,

Mavic use cartridge bearings. Shimano use ball bearings.


I'm well aware of that, I just wasn't aware you could buy the complete cartridge drom CDX.

Those boxes for cup and cone raaces are only viable for a club buy or something along those lines....
What else could you possibly do with such quantities?

Silly they don't sell them as prepackaged sets on a per wheel basis, wouldn't you say?

Bummer....

a little off topic. do the tune hubs come with hybrid ceramic bearings???


As far as I know they're hybrids. More than good enough in my book. :wink:


Ciao, 8)

At tune I can't find that they are using ceramic bearings on the Mag 180 / 200 and Mig 75 / 80. link

I think I read that somewhere on the net, on Poshbikes' site probably....

May be wise to ask before you buy.

those are Bottom brackets, not hubs. i have also read that the Tune hubs (higher end models) come with hybrid ceramic bearings, just dont remember where. if someone could chime in and confirm this it would be nice.

would be nice to know, since i am considering them now over the DTswiss since they come in 36 hole.

thanks in advance.

If I recall correctly only the Tune MAG 160 with carbon axle has ceramic bearings. Pretty useless upgrade IMO. You're talking about saving fractions of fractional amounts of friction.

Provided they're properly adjusted, the current F&R Tune hubs MIG 70 and MAG 190 are very smooth after running in.

The Campagnolo Record Bottom Bracket comes with SKF bearings - After the removing the cups, there is a faint "SKF FRANCE" logo on the bearing outer (race).

Well I think I mentioned it before, in their description of the Tune wheels the folk at Poshbikes mention Tune's using ceramic bearing for their hubs....

Excerpt from the blurb:

"Tune hubs will withstand the highest spoke tension (Less possibility of wind-up or buckling), they use hybrid or full ceramic bearings (Halving friction & rolling resistance), and are the lightest and highest precision hubs in production, available in all spoke counts, and colours."

SKF, a specialist company having it's roots in Germany has subsidiaries allover the globe.
Whike it's reassuring to find such a high quality bearing in a BB it doesn't automatically imply it's made of ceramic either. SKF makes about any bearing imaginable.

those are Bottom brackets, not hubs.


I'm well aware of that but wouldn't you think that if they'd use ceramic bearings in their BBs, they'd also be using those for the hubs?
This is SOTA equipment after all and it wouldn't be making sense if they didn't put at least hybrid bearings in the hubs either.

Ciao, :wink:

P.S. If you really want to be 100%, why not ask Tune?

That could mean anything. It would be like claiming Belgium has the best french fries in the world. You only need one person making them in order to stake that claim. It doesn't mean all fries that are made in Belgium are the best. Besides, everyone knows the Dutch fries are better anyway :lol:

I think SKF is originally a Swedish company, founded in Göteborg in 1907 by Sven Wingquist. SKF = Svenska Kullagerfabrik.

My goodness.....
Aren't we all soooo used to associate high quality precision enigneering with Germany that......We forget our friends in Sweden. :oops:

I stand corrected. :sorry:

That could mean anything.


What could mean anything?
I think the statement is clear enough as it is...If not see my suggestion in the P.S......
If that still doesn't cut it, buy the flaming things, breake 'em open and take the bearings to a lab for in depth molecualr analysis. Insist on a DNA sample too. :shock:

Besides if it takes only one Belgian to make the best french fries imagine what a small army of Belgians could do.....With fries that is..
Not that I want to start a foodfight but Dutch french fries? Like American mayo, right?
Oh, you know the Dutch invented ketchup? :frightened:

Just kidding, :wink:

I have Tune hubs and replacement bearings are around 8-10 Euro (323-403 BEF) a piece. Not likely to be ceramic.

Spoke tension has nothing to do with bearings, but as long as you brought it up Zipp claims their hubs can withstand the highest spoke tension of any hub. http://www.zipp.com/products/hubs/docum ... onhubs.pdf
Look at pages 5-7 for their explanation of this.
For certain parts stiffer is more important than lighter.
