Re: question about tubulars

I'm new to tubulars and have a question about carrying a spare-is
it necessary to pre-glue the spare, and if so, how is it best to
carry it? Or, can you put the spare on using the residual glue on
the rim-would this allow you to continue with the ride/race, or are
you pretty much done and have to limp back? Any pointers/opinions
appreciated.

Given that you didn't ask about the value or lack thereof of
tubulars and got that debate, anyway, I'll try to answer your
question without the debate.

Quoted message said:

Yes, carry a spare.

Yes, your spare should be pre-glued. Best if you ride one a bit,
take it off, and use it as your spare. If you repair your tubulars,
one of those is perfect as a spare. (I used to use a place called
Tire Alert to repair mine in batches, but I've ridden little enough
and have enough spares that I haven't had to use them lately.) If
your spare is _not_ pre-glued, you'll still get a little adhesion
but not much, and you'd be best to take it easy when braking and
cornering. (Yes, I've done this, but only on a training ride, yes
the tire rolled some but not enough to hurt me or it.)

I always folded mine up and stuck it at the back of my saddle,
sitting mostly between the rails and sticking out the back some,
held in place with an old toe strap and usually a rubber band or
another toe strap to help keep the tire folded.

Carefully packaging that spare is important because jiggling under the
saddle can wear through the sidewall and furnish a blowout in waiting.
After folding the tire in fours, tightly wrap it in a brown paper bag
and secure it with a foot strap under th saddle so it cannot wobble.

Quoted message said:

A previously glued spare ought to hold pretty well, let's say almost
but not quite as good as a freshly glued tire.

If you ride tubulars, you will soon have enough spares and these
should all have been well glued, meaning they retain about half the
rim glue which is enough to make a well glued tire when changed.

Hope that helps.

Oh, rec.bicycles.tech would be a good place to ask this one, IMHO,
so I'll add it to your list.
