Looking for 27 X 1 inch tire tubes.

[John Gialanella]

I can buy 27 X 1 inch tires for my Schwinn Superior (it has the original 27 X 1 inch Schwinn super record tires on) which I am not going to ride on. But I cannot locate any tubes for these tires. All I see is 27 X 1 1/8 or 27 X 1 1/4 inch tubes. If they still sell 27 X 1inch tires you would think they also would sell the correct tubes. Can someone help.
John.

I think you could use 700c x 25 mm which are readily available.

 

[Archie Sturmer]

I believe that 27” is 630mm in metric, and 700c is 622mm in metric; so that would be a tighter fit by about 4mm on each side, (or all around for a circle). A tighter fit might be made to work, but perhaps also introduce other difficulties — (such as when installing and removing the tight-fit tires).

The other way around, 4mm looser all-around, would probably be a no-go.

Oops, I see that you were asking about tubes, not tires.

Sometimes the box for the tubes will specify both 700 compatible and 27” compatible applications; that are often different than the marked or molded size on the tubes themselves. Online retailers might not go to the trouble of listing all of the applications.

I remember the school science teacher explaining how the inside diameter will increase (instead of decrease) when an inner tube is inflated.

So are you saying that 27 X 1 inch tire tubes are not made.
John.

700x25 or 23 will work fine. Tubes don’t need to be super exact, since they’re basically just a rubber balloon. And that’s what any bike shop would tell you.

 

[John Gialanella]

OK, but do they come with schrader valve and not presta. My bike has schrader valves
Thanks John.

I haven't ever tried to put 700c tires on a 27" rim but my gut tells me that's going to be extremely difficult. 27x1 1/4 tires are readily available, is that close enough? Tubes are somewhat interchangeable.

talking about tubes only.

 

[schwinnderella]

Yes, as indicated 700 x 25 will work and you can find them with schrader valves, check amazon,

you can buy a little adapter to run presta tubes in schrader rims
