[reply]F Note**** helmets test a little different on different riders because of back shapes and pelvis rotation. These results are for this rider but I think they generally would have the same results.[/reply]
You are right with the first part. Aerodynamics is a tricky thing...small changes in one part can have huge impact on others... If you change your bodyposition a little, another helmet might (will!) be better. Same goes with wheels and bars and everything. There is just not such thing as a standallone best helmet, wheel, frame... The only serious approach would be: Get your most ergonomic, yet aerodynamic, position on the bike set. THEN go to the tunnel and test various equipment for your own riding position. I realize this is costly and for most (me included) no option. But i think it´s the only way to go if you want optimal results.
That doesn´t mean that almost any aerohelmet is probably better then a standard, just that data from another rider means little to nothing for yourself.
