Just before leaving for an important appointment Monday I
discovered my rear tire was flat. Didn't have a spare tube and
needed to leave within minutes. Pulled off the clincher tire and
tube and put on a spare tubular tire I had hanging around. Worked
perfectly and allowed me to make the appointment on time. Weird
combination = tubular tire on a clincher rim but it worked well
enough to get me to and from the appointment.

Ummm... perhaps you should carry some duct tape. There are some
articles and a few videos on how it's done.
https://www.google.com/search?q=duct+tape+bicycle+tire+patch
I've only used it once, on someone elses tire, because the rubber
cement had dried out in three out of three patch kits available. It
apparently worked as there were no threatening messages on my
answering machine when I returned home. The only real tricks that I
recall are to make sure the tube doesn't have any crud or baby powder
on the surface, and to NOT wrap the tape all the way around the tube
so that the tube can expand when pressurized.

I don't think it would have worked with narrow high pressure tires.
The one I patched was only pressurized to about 50(?) lbs. I don't
think the duct tape patch would have held at 100 lbs.


On one long tour, our Continental Top Touring tires developed
worrying bubbles
in the sidewalls.


Is that a Conti problem? I had similar issue with Gatorskins. Two
failed prematurely when their sidewalls started to give up.

During the year of that tour (2003) I think it was a pretty common
problem with Continental tires. I don't know if it still is.

IIRC, I did later find that I'd been overinflating the tires.


I had mine at the usual 90-95% of rated tire pressure. The CST tires
never blew but their thread was gone after a mere 1000mi and the
sidewalls had lots of fine cracks which was concerning. Next up is
Vittoria Zafiro (got one of them on there right now) and after that Vee
Rubber. I don't think any of them will ever achieve the 2500mi per tire
that Gatorskins delivered but not blowing sidewalls is more important.
Plus they are not such a bear to get onto the rim.

How long do your road tires last? In Europe some people claim well in
excess of 5000mi and even while living there I never had that happen for
me, no matter which brand or price category tire I had on there. I
always lived in hilly regions though and maybe that wears tires.



... This was in remote North Dakota. I reinforced the system by
wrapping the tubes loosely with duct tape. I was trying to
approximate the
diameter of the inflated tubes. I can't say for sure it worked, but
we didn't
suffer any blowouts.


And then you fret about my hose clamp fix :-)

It still works ...

If you told me you used a hose clamp to keep your headset adjusted for a
week when crossing remote North Dakota, I'd say it was fine.

When you brag about permanently using a hose clamp instead of proper
hardware, I call it a kludge.


No bragging, it just works. Maybe I'll look for a new headset some day.
"One of these days", as Pa Kettle used to say. Though for the $25 that's
likely to cost I can get all the ingredients for a nice 5-gallon batch
of IPA :-)
