OpenPro vs. OpenPro CD vs. OpenPro Ceramic ???
 

I am getting ready to build some new wheels and have decided to use OP's. Can anybody tell me if they have experience with at least two of these three types? I am looking to find out if the extra cost associated with the CD's and the Ceramic's is substantiated.

Also, am I correct in believing that 23mm is the maximum tire width for these rims?

check competitivecyclist.com they have pretty good descriptions of them under the components>rims section

Just bought mine 10 weeks ago...I run 28mm on my OP. I'm sorry but I don't recall the advantage of the CD's.

The only upgrade that is worth it when talking open pros is to get them in black...cause they look a heck of a lot better. I own four of them, love their bombproof construction.

Mavic site says the CD in theory gives longer wheel life, greater resistance to corrosion and for some reason is easier to build. The Ceramic is supposed to have 20% better dry braking and 50% better wet braking as well as reduced heat from braking and reduced wear.

That's because there is no advantage to "CD", which is just hard anodizing. It's purely marketing.

Agreed. having a set built now!! should be ready anyday.....

I had a set of Open Pro ceramics and stopping when wet seemed no different from my Open Pro CDs. I read somewhere that the ceramic coating comes off pretty quickly.

3 of the bikes in my "fleet" have OP with Ceramic. I have these on my Spectrum Ti touring bike and have been through plenty of rain, including descents in the Alps. Braking performance in the dry is like the first time you drove a car with power brakes --but you quickly get used to it. Performance in the rain is excellent --at least relative to a normal rim. My touring bike has Campy Record brakes and their standard brake pads. I wore out a set of these within a few hundred miles when the bike was built. But since, I have used the same pads for several years. The ceramic does not wear off, but is smoothed out. It is still effective. I have also used those green ceramic-specific pads on my other bikes, and they are fine as well.
