Speaking of weight, just how heavier are these tubeless

You are perfectly free to feel that the same technology

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

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.

I don't understand what you want us to do, Tom. I've got six
personal bikes plus a tandem. Oh, plus another 1930s antique
stored in the garage attic. They have five different wheel
sizes. Surely you don't want me to run out and convert them
all to tubeless?

I have no current plans to buy another bike. If I start down
that path, I might look at the issue. But I'm not seeing a
compelling advantage.

Right now, my main issue is learning how to repair them if
there is a problem, because I do get recruited to help fix
bike problems. I'm not looking forward to dealing with the
goop.


If it were possible to make a proper tubeless bcycle tire
with out goop, we'd all ride them.

Right. Goop is the reason I not even consider tubeless. Up to the
last tire test in TOUR magazine the best tubeless tires had a higher
RR compared to the best clincher tires. Now they are on par. They are
a bit heavier and harder to mount. That would be all manageable for
me but dealing with the goop not.

Lou

But from reading posts here it seemed like the anti-flat goop was main
argument for using tubeless.

Without goop I think the chance of a pinchflat is much lower so you can
ride with lower pressures for traction reasons or comfort. That is an
advantage riding off road on a cross bike or MTB. Pinchflats on a
roadbike is a no issue for me. My flats on the roadbike are almost
exlusively caused by small glass pieces or chips of rocks. For that you
need the goop to make the tubeless tire self sealant.

Lou

Why the furor about tubeless and no flats. After all they have been
making goop to inject into tire tubes and making them self sealing for
about 30 years now. Strange that no one seems to be using that
although it is considerably cheaper - about 2.00 a wheel.

Why you ask me? Carl Fogel (how is he BTW) used that green stuff and I
didn't know anyone who patched more flats than him. I don't think that
green goop works for pinch flats. Tubeless does by default; no tube to
pinch. For road bikes pinch flats aren't a problem at least not for me.
Off road with a crossbike with 32-35 mm wide tires it is because you want
to run them at low pressure for traction. If I gonna try tubeless it will
be on my crossbike but without the goop.

Lou


Inner tubes with sealant, seem to be a bit marmite, some folks love them,
other find they simply don’t work well, clearly they can pinch flat,
equally they don’t seal all penetrating ones either.

Either way doesn’t seem to work as well as tubeless with the sealant.

Roger Merriman


Oh, right. Sealant then. For various values of 'work' maybe.

Yeah, sealant. That oughta do it. Sure.
