    Tube size help.....

    Hi,

    Brand new to Road bikes and I just purchased two spare tubes for my new 07 Specialized Allez Elite.

    The tires say they are 700 x 23. I went to a local REI and they sold me tubes that say 700 x 20/25. Did they give me the right size?

    Does the 20/25 represent the range in which these tubes fit?

    Thanks in advance.
    Eric

    You can use any tire bigger than the inside rim width. Just don't use anything smaller (bad things can happen.)

    Actually it's not a good idea to go much larger than the rim width. Sheldon has a great explanation of tire, tube and rim sizes and a chart of recommended tire and rim combos at: http://www.sheldonbrown.com/tire_sizing.html

    Which episode?
    I remember watching the one where all the sensors were out. Turned out the TV had died.

    You are fine with the 20/25 tubes. I will echo the fact that you don't want a significantly fatter tube in a tire. I've blown a tube that way before.

    Not lost, just correcting misinformation of previous post.
