We're probably going a bit OT but so probably it's about wet rides?

OK I get the message. Alu brake tracks do wear down so the material must go somewhere I guess. It's just I've never heard of anyone saying they have damaged a carbon wheel that way. Clearly no one has taken the risk.
I'm one of those people that has never taken the risk. I don't regularly check my alu pads but have very occationally over the years looked at pads when replacing them and have not noticed any metal shards sticking out.

Hi,
Clearly no one has taken the risk.
I'm sure some must have out of ignorance. Naturally it's something one brags about....

That most certainly will accelarate the process tremendously, hence the analogy.
All in all I'm really amazed we're even having this conversation. It's so blatantly obvious really.
Ciao,

Jokes aside
I've no idea if alu is harder than carbon but I would like to hear just one genuine anecdote of a carbon wheel being damaged by a pad that was previously used on an alu surface.
Is there anyone out there who has experienced that sort of damage.

OK guys, you've busted us. It's all a big conspiracy to keep newbies from riding carbon and making them less elite, and us carbon rim owners less cool when we pose at the coffee shop. It's such an awesome conspiracy that we even got the rim makers in on it: they all warn users that using pads that have been used with alunimium rims will void the warranty. It's all a lie of course. You can use any old pad on carbon rims, and only the gullible think that carbon is softer than aluminium.
I'm ashamed to have been a part of it.

Hi,
I must confess to be part of that conspiracy as well.
Before you all go "Tu quoque fili mi" on me I'll hide behind the sorry excuse that I'm not alone on this:
Even the search engine dug up more guilty parties:

http://velonews.competitor.com/2012/07/bikes-and-tech/technical-faq/technical-faq-carbon-brake-pads-and-campy-brake-modifications_230217Another one of the usual suspects:
http://www.zipp.com/support/maintenance/wheel_care_88_188.phpSince it's all marketing anyway:
http://www.competitivecyclist.com/review-brakes/swiss-stop-brake-pads_71.htmlThey enjoy writing FAQs:
http://karbonspeed.com/faq.htmlNope, not a single shred of evidence. It is quite obvious not one soul has actually tried this out.
Of course the easiest way to convince yourself is to do the obvious and actually try it out: carbon rims are as cheap as dirt nowadays, funerals can be arranged in advance, heck you can even insure yourself against the odds....
Google only showed 10 pages. No evidence, of course, we covered our tracks. Still, I'll generously leave the other 9 pages for you all to read....
Ciao,
P.S. For those who wonder how hard it is to scratch a carbon fibre brake track: I've got a bag of nails for you.

I built a carbon floor pan for a shifter kart a few years ago. The holes in it were very quickly enlarged from rubbing against the bolts which mounted it. Shards of metal in your brake pads are going to be doing essentially the same thing. It doesn't take more than a few minutes to change the pads anyway. Seems like cheap insurance to me.

This will take some weeks. Until that only the Lightweight by Swissstop pads are allowed for Lightweights wheels to avoid a loss of warranty.
Has CarbonSports done any testing of the Black Prince pads yet?
We're still testing them.
Andreas, do you have test results yet? Thanks.

I have the new pads on my bike and I'm pretty sure they will reduce the life of your carbon rims dramaticly. Why ? Brake power is more powerfull then the yellow pads and some small grid can get stuck in the deeper groves like a small stones or other scharp debris.
But I rather stop then crash into a car or other things...

Not wanting to nag, but... any results yet?
