Tubular: A tire that is installed with glue, adhered to the face of
the rim; it is a unitary assembly which includes the tube inside the
sewn-shut tire. It is much more difficult to repair than a clincher.

Clincher: A tire whose sidewalls bear against flanges on the rim,
held in place by the tire's inflation pressure. The tire and tube are
easily separable since the tire is not sewn closed.

Yes.

>Do tubulars require special rims ?

Yes, although I have seen tubulars on a clincher 27" rim once. (The
question of "why" was not answered.)

>What is better for long distance road races ?!

Opinions vary. Some conditions favor clinchers, and a few favor
tubulars.

They use what they feel will give them the best edge for the
conditions, unless they're racing for a team that is sponsored by a
tire maker...in which case, they use the tires they are given, and
presumably they learn to like them.

At the most recent MD150, a spectator familiar with the difference
reported to me that the vast majority of participants were riding
clinchers. This race is not typical, however, and should not be used
as a basis for any conclusions overall.

Tubular tires, as we call them today were the only tires for cars and
bicycles in the early days of pneumatic tires and were just called
tires then. What sets them aside is that tires have an open casing
that is held between the beads of the rim that is also (U-shaped).
This allows access to the tube in the event of a puncture while the
old tubulars could only be repaired by stuffing rubber bands and glue
into the hole.

Racing tubulars were not made as a closed hose around a captive tube
but were made as a seamless bias two ply endless belt with a tread
glued to one side. A tube was laid inside and the casing sewn shut
around what becomes a tire. This stitch can be opened to access the
tube and patch it as well as to inlay boot material where there are
cord cuts. This is a time consuming process and it requires some
skill that is not readily learned as I discovered in the years I ran
weekly tire patch sessions for about 15 years in the days before high
performance clincher tires.

I do not ride tubulars any more and have four sets of tubular wheels
gathering dust today. I see no reason for using them. The rolling
resistance measurements of various tires was enough to kill the common
believe that they roll better.

The glue offset makes them worse than better clinchers.

Is this sort of assembly legal? Isn't there something in the patriot
