Too simplistic Bulto..
You seem to be forgetting the engine rule..six per year.
True, the practicalities of current rule restrictions make modifications to the CF frame design less than viable, then there's cost and time issues too, but purely as a concept, I wonder if their problems with that frame were just geometry and nothing to do with the stiffness red herring. The fact that the first two beam frames suffered the same problems suggests that the CF not providing feel may have been a blind alley after all. Would have been nice if they could have got it to work, purely on the basis that it was different from the rest, the very ethos of the prototype formula
If they built a CF bike with the right geometry, maybe then you'd see the real shortcomings of Preziosi's design in carbon.
It's no coincidence that every bike that races at world level runs a beam frame.
Not sure about that, yes they all use the alloy beam frame now but that doesn't mean the CF won't work. Once, the frames were all tubular steel. Only takes some clever bugger to work it out and off we go again on the next evolution of chassis development. For now though, the beam frame is the benchmark.
Looking forward to the race to see if they have made a genuine step forward. Wonder if Hayden will have the new stuff this weekend. Hopefully yes and hopefully his hand will not give him problems. Two bikes will give a better picture than one.
