I've seen some exaggerations before but this one is a real whopper!Mine are carbon titanium ceramic - they actually have a negative weight value and speed up the rotation of the wheel. You could see it if you followed me climbing, at least for a little while until a slowly pulled away from you due to the aerodynamic and rotational advantages. It's science!
PLUS - all that air that leaks out from not having stem caps on stays in your tires with VSCs in place.
