hey guys, so i got this pumpo when i started riding a few months ago. ive been using the normal tubes with the valve like a car tyre. im thinking of getting slime which needs the removable valve. i just wanna know if this pump will work on the new valve?? i opened up the cap and there was this red rubber thing which had a smaller hole on the reverse, and a bigger hole and the side that im currently using so i think it will work any ideas??
