I a missing what different people are arguing about, the links gave the weight of the different tour winners and we say 18-22 until carbon dropped it into the 15 range category. To say weight doesn't matter is I assume that they are saying a 22 lb = a 15 lb bike. Well sure in a saturday group ride it is going to come down to the engine. The 22 year old on the entry level AL bike is going to beat the 40 year old over weight accountant on the $7000 15 lb bike. But if we are talking pro riders they are all in shape and they are all using similar technology and weight. It does matter to them you are not going to see a pro team roll out 22 lb bikes because that is what use to win.
