I had these RS10's as OEM equipment on my 2011 Masi Gran Criterium. I put about 1000 miles on them with no issues. I usually weigh anywhere from 185 to 195 and am usually pretty hard on things. Once these wheels were rolling, they seemed to maintain speed easily. I used these with the stock Vittoria tires, and then some Specialzed Turbo Pro tires.
I just changed to some Boyd 30 Vitesse wheels....now I know why people do not like the RS10's. The Boyd's completely changed the bike - specifically the handling. This bike corners like it s on rails now. I am still using the Specialzed tires, so that was not the difference.
Being a larger guy, I was worried about the RS10's from the start. I hit a few nasty potholes with no consequences. The wheels are still true as well.
My verdict...I feel I got lucky with my set and no failure, plus they seem to flex in corners. If you can afford it, replace the wheels.
Here is a photo of the bike with the RS10's (Vittoria tires at this point), and a photo with the Boyd's.
