I'm new to tubulars and have a question about carrying a spare-is it
necessary to preglue 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. |

You're better off with a preglued tubular but either way, take it easy
in the turns and brake with the other wheel on the ride home.

The idea of tires rolling off is exclusively related to tubulars, not
clinchers. I've used both, and have rolled two tubulars, zero clinchers.
Why don't you trot out the other usual advantages proclaimed for
tubulars: that you can ride with them flat (not high on my list of
advantages -- with clinchers, you can repair the flat, instead), that
they grip the road better (how is a matter of denial of physics), that
they don't pinch flat (I donno, I've only gone 10 years riding clinchers
with, let's see, zero pinch flats).
Look at ads for tubulars. The big selling points are that they are
"round and straight" --- meaning that many tubulars are neither, and
that you should buy this brand in order to get what most people take for
granted with clinchers.
I used to ride wonderful tubular tires, Clement Campionato del Mundo
(sp?), or Criterium Setas. Clinchers, then, were just awful. Now, very
nice, light, supple clinchers are $30, and a halfway-round tubular costs
twice that.
Sorry, unless you've got that team car following you, I just don't see
the advantages.

I'll second Dave's comments. Though I've had plenty of pinch flats on
clinchers I'll also note that one of the reasons that you didn't pinch flat
on Clement tubulars was because they put a skirt over the sewing thread. I
have gotten quite a few pinch flats on Continental tubulars that are missing
that expensive detail. Continental believes that you don't get pinch flats
if you pump the pressure high enough. That's probably so but if you ride on
the street with 160+ psi the ride on the tubular is no better than with a
clincher.
As for ride - a 95 psi tubular rides very nicely indeed and feels
considerably better than a clincher at any pressure. That doesn't, however,
translate to faster times, better cornering or longer wear. In other words,
aside from the feel there are only slight advantages to tubulars and tons of
disadvantages:
1) They are really expensive and a couple of spare tubulars are heavier and
take up more room than a couple of spare innertubes.
2) Finding good tubulars is a problem though not as bad as it used to be
before the advent of the internet.
3) Unless you really know how to sew them back up after a repair, there will
be a hard spot in the tire that feels like a lump. And the tire won't corner
as well because of that.
4) Repairs of a sewup is a time consuming pain in the butt that no one in
their right mind would take on. Racing teams want the feel of tubulars
because they do ride smoother and that might translate into less fatigue in
a long race. But they also toss out tubulars that have flatted - they don't
take chances with a repair.
The fact is that you can race better on $30 Michelin tires than you can on
$100 Clements. |

why did I just get some Reynolds tubular wheels? They were much lighter
than the clincher version, but hardly worth the difference in rolling
resistance.
I tried a set of the clincher version for a couple of weeks last year. Yeah, they
weigh more than the tubular version but they're still pretty damn light. They felt a
lot better than the Ksyriums. Certainly better on hilly rides.

clinchers. I've used both, and have rolled two tubulars, zero clinchers.
My glum expression wass due to the fact that I blew a front clicher on
the descent of a col and it did roll off as well as snagging the front
forks. Onlookers said I did a perfect somersault.
When I raced I suffered several punctures and flats on tubs. Never had
one come off, except once when I hadn't glued it on properly as I was
only riding across town. It brought me down as I sprinted away from the
lights at the Place de la Concorde. Interesting experience that was. |
