a significant reason why sram is on so many bikes in the peloton is that they pay top sponsorship dollar for it. sram marketing is wayyy wayy WAYYY better than campagnolo, or shimano for that matter.
I read a year or two ago that campy tries to negotiate sponsorship deals together with their wheels , so that my be abit tricky if the team is already on another wheel sponsor. you'll notice that most of the campy spnsored teams rid campy wheels as well. similar to shimano, but maybe shimano has more flexibility here. seeing more sram in the peloton has nothing to do with it being 'better'
I will quote the secret pro on cycling tips:
"Everyone in the pro peloton bashes one particular groupset though. It’s all in good fun, but it’s an unwritten rule that you have to take the piss out of the guys who are on that groupset"http://www.cyclingtips.com.au/2013/02/l ... son-begin/

I will bet a significant amount of money that that groupset is sram red.
A few years ago Garmin were BUYING dura ace DI2 groupsets even though sram offered to sponsor them based on rider feedback.
As a mechanical engineer who is currently using sram, has had sram parts fail on him man times and has actually opened up the shift mechanisms to understand why, I will tell you that I will most likely go back to shimano once my current sram goup gives up he ghost.
Sram is lighter, and I like the shift action and ergonomics, but it is just not rock steady solid as reliable as shimano. I could crash hard and not worry that my shimano group is going to be working fine. not so with sram. if you are a professional with a backup bike and mechanic, all the morepower to you, go ahead use sram. not saying that sram is a bad product... but the weight savings do have to come somewhere. just be aware what you're buying and the compromises you take.
I havent used campy, so can't comment.
having said that, the new sram 22 speed with road discs / hydraulic brakes does seem to be a game changer, which is going to be forcing shmano and campy to respond.
