    Do 700cc tubes work on 27 inch tires?

    I got a flat on my 27 inch tire, and living in a small town, the nearest place that is related to bikes is a REI. I called to see if they had 27 inch tubes, and the worker said that 700cc tubes work on 27 inch tires. Is this true?

    Its a ballon in the form of a circle..
    so you didn't get the tube while you were in the store ? oh you called on the phone..

    do you know the difference between a 700c wheel and a 27" one?







    math: 27 aka 630... is just 8mm bigger where the rim meets the bead . 622 for 700c

    tire fit matters, tube doesn't. get the right width 1.25" is darned close to 32mm,,

    The 700c tubes are sized for 700c and 27" with a tire diameter range in mm and inches.
    I don't do vintage, I bought them new, rode them, kept them. Now they are just old bikes

    unless they don't; both 700c and 27 inch tires come in all sorts of volumes.

    I'm pretty sure he was kidding around because of the OP's use of the extra "c."

    So they just get stretched a bit more, right? Should not be a problem considering its just 8mm more radius.

    Yes. I tried to find 27" tubes with no luck. I gave up and figured I would try 700c of the correct diameter (28-32 or something like that). I've got 1400 miles on those tubes and tires, mostly on medium-rough roads with a load in the basket, and I weigh 185 lbs. No issues and they hold air well.

    Yes Again (Oldie) ,they just stretched a bit more ,and not a problem . It easier to use the smallest size you can find like the range in this case 1" 1 1/8 " or 1 1/4" (28 -32 mm ) go with the 1" (28 MM ),makes it easier to get the tire off ,where 1 1/4 " (32 -35 MM ) will work filling the tire more but it will make removing the tire harder .

    NO! 27" and 700c cannot be crossmatched, these figures refer to the diameter of the wheel under the English (and US) in inches, and the continental system in millimeters, there is not much difference, but enough prevent cross use.
    See this for more info:

    Sometimes when I'm out doing a shopping run, I'll be offered a free sample (cut of pizza, doughnut, cheezywiz thingy)...little do they know that behind every bite is my gasoline!

    Yes! Cyclo, the question is concerning tubes. Tires will not interchange, tubes will.

    Sorry, my bad! Hopefully this will clarify any misunderstandings!

    The difference in the two sizes is 4mm in radius, 8mm in diameter.
