I've been looking to get some new wheels and i'm liking the mavic open pro cd ceramic. however i've heard some unpleasant things about the braking surface (the black ceramic coating chips, blisters, etc.) so is this just the cd version thats having problems, or is it all of them? I am aware of the r-sys slrs with the exalith, but their a little more than i'd like to/can pay. Are there any other brands that have a black braking surface that are aluminium, and of course, somewhat light weight? why not go for a silver machined surface? i admit, i'm a weenie for the "PRO" look
I dunno. I've heard of some liking them; for my road bike they were a dumb decision. For a heavy commuter bike with lots of gear on it in the PacNW, they might be a decent option. So would disc brakes at that point though.
I forgot to add mine were always loud too, regardless of toe in and make/model of brake pad.
The Open Pro CDs in my opinion look better, and do not have the headache that the ceramic coating offered. They're a real nice deep gray color, however the track wears off pretty quickly and you're left with a splotchy silver and grey sidewall.
Don't take each of the statements as gospel, it's just things people have been posting on forums ...
- they used to be bombproof, people put 100k km on them without wearning through the coating.
- there was a bad batch some time ago, with the coating being prone to chip off, be but seems the problems have been fixed.
- they eat pads like mad at the beginning, but that goes back to normal after they are broken in.
- once broken in the braking performance would not be significantly better than on alu rims, but the sidewalls don't wear through.
- they will be discontinued in 2012.
Braking is better too - more consistent, better in the wet and dry, better on long Alpine descents too.
They do chip and blister eventually but, as I said, this was after about 5 years so any rim will eventually go.
The only downside in my opinion is that they are 32h only, so building a very light wheelset is hard.
Never had issues with brake blocks myself. They do wear faster than on std. alu rims but then the braking is better.... I used ceramic block on the front and std blocks on the rear. The ceramic blocks wear better (hence the front usage) but the std blocks give more feel (hence the rear).
I used the CD rims ages ago but couldn't see the point really - the sidewalls wear down anyway, and then they are just like a regular alu rim, but uglier...
they are not light climbing wheels and mine are build up with classic CK hubs.
never had regrets from these strong wheels.
Are mavic ceramic rims back in stock?
I was browsing their 2013 catalog and it seems that some rims -reflex and open pro- are available with a ceramic coating again (dark silver box in the catalog).
Here's an extract from said catalog:
Any infos? Maviczack?
Too good to be true I think.

I can only assume it was an error. Ah well.
The new process was rubbish and meant that the coating will fracture and fall off.
Probably why they've moved over to their new exalith process.
