    Schrader Stem length

    Hi all,

    I just bought a new bike and it has double wall rims with schrader valves, and I'm not sure if they come in different lengths like Presta valves or just one standard length? I want to pick up a spare tube without removing the tire to measure the length.

    Thanks in advance.........

    I have never heard of different schrader valve lengths. I have found that some pump heads work better with short valve stems then others. For example I have two home pumps, one has an auto selecting head and one has a separate head for presta vs schrader. I've found that the pump head that has a specific head for each valve stem type works better for short valve stems.
    A wild man once explained to me how bicycles came from sailboats.

    Schrader valvevstems are available up to 2in in length. The only thing you need to confirm is that the valve stem will clear the rim and give you enough length to put on a pump. So longer is OK but too short won`t let you fill the tire.

    In the long run its your rim profile that decides acceptable length. Just visit the shop where you bought the bike. They probably stock what you need.

    The recent large numbers of Wal Mart Schwinn Varsities, GMC Denali's, etc. in the world has created a decent market for longer stem schraeder valves because these bikes come with fairly deep rims with schraeder valves. The stems are 48mm long, and I don't think Wal Mart carries them. At any rate, we do have a market for them, and keep them in stock. We refer to them as "Wal Mart tubes." I'm sure not all bike shops carry them, but they are available through wholesalers, so bike shops can get them.

    Our LBS doesn't carry them; they never heard of such a thing, either. I have a couple I could show them, but they're in use.

    W-M doesn't carry them, and the bike manufacturer treats them like Kruggerrands -- almost like they're not allowed to dispense them.

    Well it's not a Wal-Mart bike, it's a Gary Fisher (Kaitai) and I bought it from the LBS..... It has Bontrager AT700 rims if this helps.... Maybe I should just take one off and have a look?
