Assuming that you're looking for dual purpose race/train wheel, Rolf Vector Comps aren't a bad wheel. My wife spec'd her P2K with these but I bought her Heds for x-mas so now she uses them only for training, but they coud be dual purpose.

I have the Rolf Vector Pro's on my Trek 5200, and I agree that they are a great training wheel. They are totally bombproof! However, despite their cool "aero" looks and reduced spoke count, they aren't a particularly aero wheel according to John Cobb's review. I don't know how they compare to other mid-profile (30-40mm profile) wheels, but they certainly aren't as aero as a deep section wheel. The other thing to consider about the Rolf's is that due to their high spoke tension they can be a little punishing for lighter riders. I'm 6'0", 160 lbs, and they feel fairly stiff to me. For a lighter rider they may be a little harsh. Great climbing wheel, though. All in all, not a bad racing wheel (I'll be racing on them until the budget permits a better set) but it's no Hed or Zipp.

Thanks for your suggestions. Yes, I'm looking for a dual purpose wheel for both training and racing. Has anybody heard about the VeloMax Ascent II? What do you think about them?
