    Help with Wheelset measurements and tires

    My Iron Horse Cyclone Road bicycle was damaged in a storm. The front and back wheel were bent and I now have to buy a whole new Wheelset. I use this bicycle for commuting and racing for fun (I'm a college student and can't invest much into the bike for serious racing just yet). The tires are still in good shape and are 700 X 23c. My tire tubes are 700 X 18/23. I found a nice wheelset in my price range that measured 700c X 20MM. I am trying to learn more and more about my bike but I have never had to deal with this before. Does anyone know if this wheelset will work or am I going to have to buy new tires as well? Any suggestions from a more experienced road cyclist?

    Thanks!

    A 20mm rim will fit a 23C tire no problem. I'm not sure what the cut-off is for what you are looking at. More info would be helpful. But a 23C tire is a sure-fit.
    How do you keep an idiot in suspense?

    If 20mm is the internal width measurement of the new rims you might want to think twice about trying to put a 23mm tire on there as the tire would be quite skinny for such a wide rim.

    Check the bottom of this page for some width recommendations:

    If the new rims you are looking at are in fact 20mm interior (from bead seat to bead seat) then they are probably touring or hybrid style rims designed for a tire wider than the typical road bike tire. If the 20mm is the external measurement then Panthers007 was right and 23mm wide tires would probably be ok.

    All it has on the info sheet is 700c X 20mm clincher. The model of the wheelset is 2009 Vuelta Zero-Lite. I will go back to the dealer's shop and see if I can dig up a little more info. Thank you for stating this. Like I said, I am new and really don't want to mess up.
