Hi again ! It seems sometimes you see what you want and in my case frontspoiler came footspoiler I still wonder what the america's frontspoiler funcktion is.. didn't find it out in net.
In any case after reading the email through again (and doing some ergonomic tests) I'm turning to feel strongly what Moe said is a fact in my case. It's the whole ergonomic package. I've already adjusted the handlebar a bit and next step is to buy a backrest. The backrest will allow me to push back against the wind also with feet (against the pegs). I've found a promising backrest model from Protac. These as start, if don't help then I have to dig somewhere more bucks.
