The difference is there but it is so small it can not be instantly "felt".
An aero wheelset will save you a few to a bit more than a few seconds over let's say 20k ... that's it.
A lighter wheelset will save you some time on hilly courses and will speed up faster ... that can actually be felt but even then the difference is small at best.
Adela, this is entirely depending on what wheels you are coming from. If you can't feel the difference between some Araya/Allexx Wheels and a pair of zips aero or not, you shouldn't be riding or at least concerning yourself with wheels at all. Yes, it is usually the radial weight that makes the difference in feel due to spinning up faster and overall carrying less weight. I'm not saying that you would most likely notice the big difference between 32mm and 38mm wheels, but going from a 24mm rim to a 38mm is a pretty significant difference. I am sure much of the affect will be placebo, but there is not denying just how powerful the placebo affect CAN be.
