"While I honestly doubt anyone can really feel the difference, there are plenty of people who swear they can." Problem here is that most people will have one bicycle, which makes it hard to compare. When I started cycling again, I bought 2 bicycles, in 2 slightly different sizes to get a feel for the right size. One was made of classic steel, one was made of oversized aluminium. I really could tell the difference over rougher roads. To my surprise, wheelsets made just as much difference. When switching different wheelsets, I could double the comfort of the steel bike by matching it with really nice wheels. With the aluminium bike I could double the harshness. Using the steel bike with the hard wheelset and the aluminium bike with the nice wheelset, made it somewhat even for me. If you need advise for a nice wheelset, I can heartily recommend a Campagnolo Scirocco wheelset :)
