long cycle wings

Clamshells produce a lot of drag and lift at speed.

I borrowed a pair to try to fit to my chassis. The thing is, if they don't fit they are real hard to adjust. They bolt to the sides of the chassis, so if your track is too wide about all you could do is fit big spacers between them and the chassis. Or try to modify the glass, but that would be a challenge.
