As I've already posted, I changed my first flat tire today, and noticed that the presta valve on the new tube is considerably shorter than the valve on the first tube. What's that all about?
Also, what's the point of the little ring that screws onto the valve and sits at the rim? Is that to keep the valve from getting pushed down when I inflate it or check the pressure?
thx!
