Getting my Bike Friday ready for a ride yesterday, the back tyre was flat and on investigation I found the valve stem terminally separating from the tube. No spare tube to hand and no chance of repairing the tube so I tried a trick I had heard about. I carefully laid an uninflated 28-700c tube into the tyre carefully folding the excess length back on itself and forward again in an s-shape. Put the tyre back on, inflated slowly to 100psi and all went well. Took a second one with me on the ride in case the first one didn't last but it's held up well. So if you ever get stuck for an inner tube for a small wheel bike, give it a try.

Did you find the ride as smooth as it should have been, or did you find a mild thump each time the folds came round?

Totally smooth and unnoticeable. In fact I am going to leave it in and see how well it fares given the relative costs and availability of a 28-451 and 28-700 inner

I had a flat in the front wheel of a bike I bought second-hand and had been riding for over a year and was amazed to find a folded tube inside.
There was absolutely nothing unusual about the ride and the tube had lasted at least over a year..

I bought a bike that had a bump in the front tyre. On investigation I found a 'universal' innertube - the sort that is a cylinder rather than a torus. I replaced it with a regular tube and the bump went away, but I kept the weird one as a get-you-home spare.

The tubes cost the same and are readily available from most of us recumbent dealers.

AVC 451 Schwalbe inner tube £4.99. Wiggle: 700 inner tube £3.99. What do you charge?

that's different retailers and different brands, which makes the comparison fairly meaningless given how much tube prices vary.
At AVC, all Specialized tubes, from 12" to 27", are £3.95
The only consistent price difference seems to be that long valve tubes cost more than ordinary ones.
