Don't pay MSRP. If you can get a pair for about 400 bucks, go for it.
If you are paying 500+ bucks, consider williams system 30 (or maybe even 30X at your weight).
Or if you want to save money and get reasonable wheels in the 300 range look at neuvations.
And of course the "CAAD9" of wheels, open pro's/ultegra hubs.
Did you ask psimet?
