Condor Posted September 5, 2011 Share #1 Posted September 5, 2011 I picked up a TREK 7000 mountain bike at an auction yesterday and it has the goofiest looking valve stems on the tires. I've never seen anything like these.... ever. They kinda have a double threaded stem, and the larger size looks smaller than what you normally find on a bike tire. Anyone know what these things are, and what kind of pump they take?? Pic attached... Link to comment Share on other sites More sharing options...

Snaggletooth Posted September 5, 2011 Share #3 Posted September 5, 2011 Yep. Called a Presta valve. A bit smaller. Talks a special end for the pump. Most bike shops carry the pumps that fit it. I ride a Trek also with the same type. Mike Link to comment Share on other sites More sharing options...

Condor Posted September 5, 2011 Author Share #5 Posted September 5, 2011 i custom built my specialized hardtail. Very cool!! Thanks for the YouTube. I guess it's off to the dealer for a smart pump...and a couple of caps.. I have never seen one of these before. The bike is cleaning up very nice. One thing I really like is it's 'Handbuilt in the USA' Link to comment Share on other sites More sharing options...
etcswjoe Posted September 5, 2011 Share #6 Posted September 5, 2011 You will love the Trek I have had mine for 3 years now and it is pretty much indestructible . Link to comment Share on other sites More sharing options...
kevin-vic-b.c. Posted September 5, 2011 Share #7 Posted September 5, 2011 you do not have to purchase a special pump.... most cycle shops sell a small adapter to go on the stem so you can use any air pump. Just like riding the motorcycle..... All the gear all the time ! Helmets save lives. Link to comment Share on other sites More sharing options...

Seeing that your scoots (with engines), don't get ridden much at all. :rotf: Link to comment Share on other sites More sharing options...
