This thread is unclear. Are you having trouble with the stock windscreen, or the DP race screen. As far as I know around here, nobody actually rides with the stock screen. I'm 5'6", and the DP one works fine on the road and the track.
This thread is clear, I never mentioned the DP screen just a possible upgrade to a double bubble. No one rides with the stock screen? Are u sure about that buddy? The picture thread shows many a stock screens!
Hootsmun, I agree with having the jacket adjusted I believe this will help a lot of the problem.
However I've just had my first fast ride with the race seat fitted and aero wings fitted and it was a night and day difference! I don't think the aero kit had much to do with it except for taking a little wind off my hands and forearms. I do believe though with the extra height of the race seat that the air now hits me lower in the chest.
Everything is as smooth as silk for me now! I think if I fitted the double bubble that it would end up shooting the air back up around my shoulders resulting in the same issue.
Btw..even at 5'7, the extra seat height is no issue at all!
