Source for 28" tubes?

wiggle.co.uk has 700c tubes with either shraeder or presta valves that
are suitable for tyre widths up to 47mm. May not be much use to you in
the US though...

The ones I saw are made by Continental if that helps (German
manufacturer, also make bike and car tyres - not sure if they're
available in America?)

Hope that's some help to you 🙂

My 28 Sun uni tube blew the first day, same tub you describe. The bike
shop sold me a smaller tube (don't know the size) but it contiues to
work fine.

Especially if it's a Sun, be sure to check for metal burrs inside the
tire. I put that tube protection tape around the inside rim to better
protect the tube.

I had looked for the correct size tube, and found a web site. Never
order it, but it should be in my favorites list at home, I'll post that
tonight.

I don't know about the tire valves.

I appreciate the suggestions, Rob and Chrashing. Yes, it is a Sun and
the puncture was on the rim side of the tire. I'm going to pick up some
solid rim tape tonight to prevent possible recurrences.

I'd stock up on replacement tubes if I could find a good source.

On the other hand, my 20" uni is still on the original tube four years
after purchase. Go figure.

The tube that came with the uni is marked "28 x 1 1/2".

One shop said they have a 700 x 38 with a presta valve which I can adapt
with a collar. Will that work?

28" = 700c and 1 1/2" = 38.1 mm. The shop is selling you the same
size tube. The only issue I can think of is that the hole in the rim
is bigger than you need to fit a Presta valve. I don't know if that's
a problem.

The Presta to Schraeder is small and will work fine (assuming you need
it - some pumps work on both valves).

Sorry so late Ken, but I selfishly had to shorten the SUN uni fork neck
an inch before I logged on the web tonight. (Not the seat post.)

I went to a bike shop and showed the owner the tire. He dug around and
found a 700 x 48 with a Presta stem. He told me the 28 x 1 1/2 that had
been shipped with uni was too small for it.

He gave me a small rubber collar to insert where the valve stem goes to
accomodate the Presta. I put everything back together tonight and gave
it a test ride with 80 psi. Nice ride....
