The Niklas NACA Duct

Looking for more cooling in your velomobile? This large NACA duct is the answer. Specifically designed by Niklas Bostelmann for installation in Milan velomobiles, this duct should work in any velomobile with a large enough flat surface to install it on. A full-scale PDF is available for those wishing to test the placement prior to ordering. 

Installation will requiring making a cut in the hood of your velomobile. The installation PDF includes a template for use when cutting. The duct can then be glued in place using epoxy or sikaflex. The screw allows you to operate the flap you will cut in the velomobile just as is done in Milan MK7 and Bülk velomobiles.

Duct size is 243mm long.

Color will be either gray or black depending on filament availability.
