Dave Mayer said:Here are the basic advantages
- Tubular wheels are 200 grams lighter per wheel (including tires, tubes,
rim strip, etc.)
That is way past the comparisons I have seen, or made. Yeah, the rim
itself can be lighter, but not as light as the good old days with a modern
9-10 speed cassette. Maybe 50g there. The rim strip is not all that
heavy, not even a good one (see below), and a comparable tire would be
comparable in weight, be it clincher or tubular. Both have the same
casing and tube. A tubular does not have a bead, but a Kevlar bead is
pretty light. Clinchers don't have a rim strip as part of the tire, nor
the part of the casing on the bottom of the tire. I'd say no more than
100g total weight savings for a tubular versus a comparable clincher.
Quoted message said:- They are
inpervious to pinch flats
Not really. In the circumstances you describe, hitting a pothole, I have
had pinch flats with tubulars. The mechanism is the same. Tubular rims
do not have such an edge as clinchers, but they do have some edge to them
and a hard contact will do the same thing to either tire.
Quoted message said:Safety. When tubies go flat they do not turn into some writhing mess of
rubber on the rim while you're coasting to a stop.
Actually, they can. And, clinchers can stay put quite nicely.
Quoted message said:I cannot imagine
what happens to clincher riders during a sudden blowout at high speed -
especially while cornering.
The same things can happen with either tire. There is no magic to
tubulars here, and no disastrous weakness with clinchers.
Quoted message said:- Tubular wheelsets generally cost next to nothing. I have about 20
sets of wheels obtained from yard sales and donations from ex-racers. I
think the most I ever paid for a set of wheels was 50 Canadian Pesos for
some mint high-flange Campy Record units.
This is absolutely true. But you might wonder why, with all these
advantages, people are dumping their tubular wheels in garage sales.
Quoted message said:I've ridden the same set of tubulars for the last 5 months. No flats.
10cc of Slime in the rear tire makes sure of that.
5 months without a flat is hardly a record.
Quoted message said:Second clincher ride today. The rim strip blows through while I'm on
the road. Some green plastic thing. That never happens on tubies.
If you use [censored] equipment, it would. Use a decent rim strip, and don't
blame the tire design for it.
Quoted message said:Instead of a 2 minute change with tubulars,
the fix involves begging for
Quoted message said:electrical tape to wrap the rim, wrestling with a brutally tight kevlar
bead with 3 tire irons, then pulling the whole mess apart again because
I'd made a tube tear as a result of getting the tire back on the rim. 30
minutes of swearing and sweating in the heat.
Well, there are some tire/rim combinations that are better than others. I
can take off and put on my tires without tire irons. I have had problems
with some rims, but I don't use them any longer.
