Hi, just a quick Mavic question here. I've ordered a Mavic EX721 CD rim, and was told CD is NOT the same as a ceramic rim. Should I still use cermic brake pads? I'll be using my beloved Avid Arch Supreme rear brake, and I do have both ceramic and regular pads. Thanks a lot, I just want to get the best braking power I can.

is Mavic's CD process the same as a ceramic rim at all, or is it a gimmick used to think you get that claimed 60% better stopping power like a ceramic rim?

Thanks a lot!!

Have a look at the attached from the Mavic website...

You'll notice these rims are coated with Ceramic 2 which, means you should use ceramic pads.

Only if it is the Ceramic version. The EX721 is offered in three different versions: silver (no CD or ceramic), CD (anodized), and Ceramic (anodized and ceramic coated). I have not seen the ceramic version in US sources.

Well, here's the link to the exact rim I ordered. http://www.speedgoat.com/product.asp?part=82109

I'm still unsure to which mine is exactly, but am leaning towards using ceramic pads...

Will it say on the rim when I recieve it, whether it is Ceramic or just CD anodized??
Not a ceramic rim. This is a ceramic Mavic: http://www.speedgoat.com/product.asp?part=82090&cat=260&brand=155
The label will tell you exactly what version it is, just as the Speedgoat description does.

You can use the ceramic pads but they are usually not as good on regular rims.

It will say "Ceramic" on the rim if it's ceramic, but you can also tell by feeling the sidewall of the rim. Ceramic rims will feel just a little bit like VERY fine grit sandpaper. I don't think the rim on the link you posted is ceramic though. If it was, the guys at speedgoat would tout that fact very clearly. Note: Normal black pads will wear quickly on a ceramic rim, but won't damage it. On the flip side, I have seen the green ceramic pads wear the anodization off non-ceramic rims. Bottom line: if you're not sure, try the regular pads first.

Which is a good thing. Anodized sidewalls brake very poorly in the wet. I use to use abrasive pads on new rims and ride in the sand to wear through the anodizing as soon as possible. It is one of the reasons most anodized rims now have machined brake tracks.

Alritey, I'm thinking of getting an actual Ceramic rim now too, and build/sell the CD rim. Can anyone recommend a all black, ceramic 32h rim, that if possible, is slightly wider than the standard width rim? I am looking for something that might be a little pricey, but that's cool with me. I didn't think Mavic made any black, 32h ceramic wider rims, but I may be wrong. I also don't know if there's many other companies that even make ceramic coated rims other than Mavic, and possibly bontrager...

Thanks so much for your help!
