Driving the rear Smart Sam with my Deflator Cap until it's completely flat

I build myself a deflator cap which presses on the valve and allows the air to flow out of the tire. This way i'm loosing air while riding my bike and the tire goes flat

Very nice Clip I love it :)

The deflation cap looks so special. I used to insert some paper/napkins in the cap to control the speed of deflation.
