Does anyone know, with any degree of accuracy, what the difference, in time/watts/whatever, between a bike like the old work horse Cervelo P2 or P3 and a new "super bike" like the Felt IA or Canyon Speedmax? I've been out of the triathlon game for a long time and am looking to get a new bike (I sold my previous Felt DA) to start competing again. I'm on a limited budget of ~$3500 and I want to know if I would be better off getting a cheaper bike, like the P2 (P3), and getting some decent wheels or getting a nicer used bike and buying wheels down the line (6-9 months). If we're only talking 30-60 seconds over the course of a 70.3, then I'll likely stick with the cheaper option, but I can't find any real data anywhere.

For reference, I've already got powermeters that can be swapped from my cross bike, so I don't need a new once of those.

Thanks!
