I know of three typeS of bike valves: the old "English" style, still common in China, Schrader valves, the same as on car tyres, common on fat-tyre bikes. But better are the Presta or "Italian" style, as used on racing bikes. These hold the pressure much longer. As they're not so common, casual vandals often leave them alone. A decent up-market bike shop should have tubes in all sizes with either style of valve, and they should all cost the same whatever kind of valve. If you do, of course, don't let on that's why you changed the tubes, if they think you're trying to outsmart them they can slash the tyres or trash your bikes. You'll need a Presta pump; or a little converter that screws on them to let you use a car pump connector. They're the same thread as English valves, so a cheap English pump will work too. http://www.google.com/search?&q=schrader+valve+presta What kind of valves are these?
