Speaking of weight, just how heavier are these tubeless systems compared
to the old tyre and tube system.

You are perfectly free to feel that the same technology used on every
other rubber tired vehicle in the world is not suited to bicycles but
if you're going to argue, don't use inadequate responses like "lock
you in to their products"
or "testing procedures are only for very narrow test conditions."
when this isn't the case at all. It is far easier to test bicycle
tire performance than those of a motorcycles.

Why are you arguing this? Tubeless tires are missing the weight of a
tube. What's more, because the sealant is so reliable you can use
lighter racing-style tires rather than armored tires such as the
Gatorskins or the others of similar construction. The flat tests I
presented earlier was a guy riding Continental 4000's - a racing tire
that has minimal rolling resistance in the tests.


People like tubeless for some applications where they make
sense. Other people gave up on them in other applications. I
don't feel strongly either way but they are certainly no
panacea.

Regarding weight, at least for road sizes, you're using a
heavier rim liner and a heavier valve assembly plus 55~60
grams of latex to omit a 60~65 gram tube. There may be a
weight savings but it can't be significant.

People like what they like because they like it. That's
fine, and argument enough. I don't see a compelling reason
to change, certainly not from 300g tubulars. YMMV, and in
your particular case it does.

p.s. I drove a wire-wheeled car, the last 8 years with the
latest hi-zoot Pirellis and matching tubes. Worked fine. Now
that I'm a grownup, I like pressed steel wheels with
tubeless, which are lighter.

Well, I can't argue that people want to ride what they want to ride. I
just find it curious that they complain about flats and then won't change
over to a tubeless that doesn't get flats.


Huh? Last time I rode with a guy using tubeless we had to stop every 30k
to pump up his slow leak. I’m not saying tubeless suck but saying they
don’t flat is wrong.
