totally relative question. How much is that $1500 worth to you. Over a 50k TT that Cervelo P3C will save you 1-2 seconds over the BMC. Are you going to win or lose a race, or races by that much? I have been looking at TT/Tri bikes for the last couple of months and have settled on the Specialized Transition as the best bang for the buck. Of course I watched the TDF TT yesterday and noticed that the Gerolsteiner (sp?) team, sponsored by Specialized, was not riding the Transition. Of course I have no real need for a Tri bike of that level...but I have more money than sense.
