Puig sports screen, it's all about your height, there's a ton of info on here, go low with the screen and get the wind onto your shoulders, not your face.
Any need for the Palmer products adjuster with the Puig sports screen, or is it grand without? Suppose I could try it without first and see.
I had the screen spacers, the Puig screen, screen deflector, wings. None were as good as a short one leering the clear air straight at your upper torso.
I have also have put narrower bars on which makes me sit slightly further forwards which seems to help.
None of them stopped the buffeting. In the end, I fitted a carbon Pikes Peak screen which allows clean airflow onto my chest and head. Wind rush, but no buffeting.
Take the screen off and take the bike around the block. It will be windy but no buffeting. I cut my original screen down a couple of times to test it out, go low.
