Flyscreen works very well. I think there is just a bit of turbulent air at my chin but no wind is hitting my chest while riding (keep in mind that there were very strong winds almost everyday I rode since I got this flyscreen). The screen shines especially in speeds above 75 km/h. I'm 175cm, so if you're similar height I highly recommend it.
My second Dart flyscreen. Beautifully made and a perfect fit. Well packed an promptly delivered.
Does what it’s designed to do and in great style. No more wind blasting chest.
