DA Open Pro Ceramic

1. Lighter
2. Proven reliability
3. Good looking in an understated way
4. Easily Overhaulable hubs
5. Dependable, strong rims

I'm not saying the Vector Comp is a bad wheel- just that I'd rather have the Dura-Ace/OpenPro

Gotta agree with the above poster. If it's between those two sets only, go with the Mavic rims. Personally, I wouldn't pay a dime for anything Rolf. Those Vector Comps probably weigh in at 1900 grams or more. Heavy!! I've heard more complaints about Rolfs than just about anything else. Who's going to fix it if anything goes wrong? Although he's trying to fire up another business, he is not viable at this time.

For comparison sake to your Open Pro idea, read on. For less than $400 you can get into Velocity Escape rims, really nice Wheelsmith AE15 spokes and pretty darn good Am. Classic hubs. Whole set will weigh in around 1500 grams. Real weight, not published weight. That is approximately a 2000 gram rotating weight savings. (Using the loose rule of thumb theory of multiply weight savings x 4).

Ceramic rims will eat your brake pads faster than Homer Simpson eats donuts!

Made the mistake of getting some and on the first ride the fork and rear triangle was covered with black dust. They do break-in some (no pun intended) but it's best to use some ceramic specific brake pads. Also, if a stone flys up and hits the braking surface, the coating will chip leaving a skip that feels like an uneven rim joint seam.

I took my off and got some new rims.

I have ceramic on my mountain bikes wheels. They do stop better in dry conditions and especially in wet conditions, but I don't have experience with them on the road bike. Anyway, I had the Vector Comps on a Trek 5200 I owned. Decent looking wheels, held up fine, but they are heavy. I think the other post of about 1900 is correct. The D/A w/ Open Pro should weigh less than that.

Kool Stop makes specific pads for Ceramic braking surfaces. MUCH harder composition. Z-Chromium Compound Part # KS-DURAC
Rolf still making Vector Comps?DINOSAUR

Thought those were made for Trek bikes? Is Rolf still making wheels? Parts problem down the road, been there done that, nod to Mavics...
Depends on the ride.Quack

Funny you should ask. I only have two sets of wheels and they just happen to be the two you mention minus the ceramic coating. We get rain about 10 days a year here. The Open Pro on Dura-Ace wheels are great for anything that requires comfort and quick acceleration as they have less overall tension and are lighter than the Vectors. I personally use the Mavics for training, racing, and commuting.

The Vector Comps are great for any type of open road solo effort like time trials or long training rides in the wind. They are slightly narrower than the Mavics and much more rigid. Sky-high tension and the aero rims add up to a bit of a jarring ride over uneven pavement but you are rewarded with better aerodynamics and higher average speeds. I track my average speeds during all my rides and they are always 1-1.5 mph faster with the Vectors than with the Open Pros. I haven't done any sprint tests comparing the two, but the Mavics do seem to be easier to accelerate than the Rolfs. Most likely due to the light rim and aluminum nips.

As far as the hubs go, I would call it a dead heat. They are both smooth as silk. The Dura-Ace does look sharper and has a much quieter freehub but then how often are you coasting anyway?

Don't be too afraid of the horror stories involving Rolf's wheels. Loose spoke nipples are easily fixed with some threadlocker or spoke freeze and he still makes replacement rims with the same drillings. I've gone through both my wheels with low-strength Loctite and they are now rock solid reliable with no creaks going on 1500 miles.
