    29er tubes with longer presta valves?

    I am having difficulty with using "standard" length presta vlave tubes with Mavic Speed City wheels due to thier tall profile. One of my floor pumps works pretty well but I struggle on trail to get air into the tubes with the short valves.

    Is there a source for longer valve tubes?

    I have valve extensions but they only work with removeable cores and I have yet to find 29er tubes with removeable cores. I have also found some Salsa tubes that go up to 44mm that have 40mm valves listed on Salsa's site.

    I know there are others using tall profile rims out there. How do you deal with this issue?

    Thanks!

    The Bontrager standard 29", Lite and Slim'd tubes are 48mm valves.
    How many do you want?

    Tubes w/ long valves are best, but for that time when you can't get one, a valve extender can come in mighty handy. Your LBS can order from QBP easily.
