Presta Valves are the most secure valves because the air is locked in the tube with threads instead of a spring ,as on schrader valves. Great advise from all the people ...
Get a shop quality floor pump, with presta, schrader, convertable head, and large display easy to read guage.Some pumps can go as high as 160PSI with no problem...
In my opinion the worse valve ever made is the British valve, used all over Japan on all those "MaMa Cherries" Shopping Bikes(mothers chariot). If you don't know about them consider your self lucky. Here in Japan they call the Schrader valve the American valve. And you can pull into any gas station and get
410 KPA (About 62 PSI) for your Mountian bike tires.They always say..." No, No, air for British valve" then they look and see that it is the same as a car valve and they freak out. "How did you get an American valve on your bike ?.". and I say... In america... we all use car valves on our bike unless using a presta valve. they they say...
domo go ziemas... or Thank you very much.
well good luck to all!
