Trust me to start this one up
For the men's RR I think the Spanish on paper are almost unbeatable with all of them potential winners, but that can also cause problems as well if more then one of them on their day is going strong and Paolo Bettini is also a big favourite. He is a big race rider, he has been two time World Champion plus many other big classic wins including the Tour of Lombardy in '06 a week after his brother died in a car crash.
For the track events, GB's Mark Cavendish and Bradley Wiggins should be able to clean up in the persuit (and they are 100% clean, you can trust your bottom dollar on that) and Victoria Pendleton should be able to get a medal as well plus the squad led by Chris Hoy (A Scotsman BTW).
Dunedin's Greg Henderson (have no idea if he is well known or not there)is a chance of a medal as well.
