I just pick up a set of ceramic coated Deep V's. I have heard the braking surface is suppose to be better but are there any other pros or con to ceramic coating.
Thanks

Ceramic? really?

Ceramic braking surfaces are my jam. I have no doubt that it works to stop your bike faster than a regular machined rim, I can feel the difference every time.
I know of no cons, other than the fact that ceramic rims cost more. I had no idea that ceramic Deep V's existed.

That is what I was told. The braking surface is a bit more roughed up than normal braking surfaces right? If so then yeah they are ceramic.

Hmm, I don't know what that. My ceramic rims are smoother than a baby's bottom. I don't know what the science is, but I don't think it's a rougher braking surface.
Edit - Upon further examination, I may be confusing my Mavic CD rims with ceramic rims, which are apparently different.

the first con i can think of is the number of toilet seat jokes you're going to get...

As far as I know there aren't any ceramic-coated Deep V's. It takes special sputtering equipment plus high temperature oven to apply ceramic coating (at least a ceramic coating that will stick) and Velocity doesn't have this. You may have anodized Deep V's.
Ceramic coatings have largely fallen out of favor. I think the only rim still offering them is the Mavic Open Pro Ceramic. It wears brake pads faster and offers weaker braking overall, but on first touch it avoids a film of water that causes something similar to hydroplaning with the brake pads. It's not very thick but it still will insulate the rim a bit from heating so the rim stays marginally cooler -- OK I suppose in hot weather but in the rain it means water doesn't vaporize as quickly. The one big plus of a good ceramic coating is that it protects the braking surface from brake wear. However, the majority of ceramic coatings I've had have tended to flake off in patches over time. A good brake pad and a bare aluminum rim brakes better and more consistently than anything else. If the aluminum is anodized, it doesn't really affect braking significantly, but I wouldn't worry about ceramic braking surfaces.
