Pros are still winning races on aluminium frames. The importance of materials is overstated. Also, the weight difference between alu and carbon is often less than 200g. Some of the Look carbons aren't that light at all.

Alessandro Ballan and his teammates were even racing steel in the recent "Classics" (!!!), and it wasn't the frame that prevented Ballan from winning, it was his legs and/or lungs........or his mind?
