For racing purposes, I agree with you fully, mickeg. I'd like to see strict "spec bike" rules where -- except for sizing and gearing choice to accommodate rider fit and ability -- all the bikes were essentially identical, regardless of maker. If they're to be all carbon, then make them the same, though I'd like to see a return to steel for the sake of tradition.
What I really want is a level playing field where the difference is due to the efforts, talent, and skills of a "clean" non-doping rider. I'd also like to see radio communication between the team cars and riders banned on the major Classic tours like the Giro and TdF. This would put more emphasis on rider and team tactics on the road. Part of the fun would come form the audience "knowing" things the riders don't, thanks to our helicopter views and announcer commentary.
Best,
Dan. (...who would not mind a Tour de Luddite if it made for good, honest racing)
