You obviously don't know as much about wheels as you think you do. Consider that you have a pneumatic tire mounted on the wheel and it's inflated to somewhere between say 80-100psi. This is a normal road size tire, 25-28mm. If you sit on the bike you'll see the tire squish a bit. If you squeeze it with your thumb and finger it'll squish a bit. This happens ALL the time when you're riding, the tire is constantly squishing a bit. Now look at your wheel. The spokes are under a LOT of tension, normally 100-120kgf. For you to feel any difference in ride quality between wheels you can guess what might have to happen. The tire would have to squish to a degree that the rim would be hammered into the tire, much like what happens when you get a pinch flat. Then you'd have to have a rim that would be flexible enough to result in spoke tension going down to near zero or even less than zero and somehow be able to return to exact and proper tension every revolution of the wheel. Do you really think this is what happens? Now look at carbon rims. Even low profile carbon rims are very very stiff radially. I've built hundreds and hundreds of wheels, both aluminum and carbon rims. You don't even build them the same way. They don't get the radial hops that alloy rims do because of the stiffness. Some people talk about carbon wheels damping vibration better than alloy rims. Do you honestly think you'll notice that difference with the pneumatic tire and it's soft tread between you and the road?
