There is a valve out there. Outside of Italy it is rare and not well known . 'Valvola Regina' . Sometimes it is called 'valvola classica' . Apparently the woods valves are also called classica. What kind of valve is this? I know it is similar to Presta valves. Is it generally compatible with the common presta pumps?
One of my bikes came with them one once. I was so misguided they got tossed because I wanted woods valves.
