tufo tires/rolling resistance(3 posts)

I have seen reviews and discussions on RBR and other sites that tufo tires either:
1) have a lively ride with low rolling resistance and are favorites on the track, or
2) have a dead feel with high rolling resistance
This seems to be true for several of their models-a great divergence of opinion.
Does anyone have any data?
What are other folks experience?
I think I'll try some because their technology and construction looks state of the art, but its how they actually work that is obviously important.

If you are talking about Tufo tubulars, they generally get a good review, though some don't like the fact that they can't be repaired like a normal tuublar. If you're talking about the Tufo "clinchulars" you might be interested in this quote from the latest issue of the RoadBikeRider newsletter:

Tufo (www.tufo.com) is a unique product in several ways. The
tubulars seem normal enough, albeit without tubes as we know
them. But the "tubular clinchers" are one of the weirdest
(and cleverest) designs I've seen.

Hailing from the Czech Republic, where the winters are
l-o-n-g and the nights are c-o-l-d, what else is there to do
but reinvent the wheel? I mean tire.

Like its tubulars, Tufo's clinchers have no tube. That's where
the similarities end.

Built onto the bottom of the clincher is a channeled rubber
band (as Tufo calls it) that takes the place of the bead on
a regular clincher tire. It locks the Tufo to the rim.

You don't need rim tape when mounting a Tufo. You do need
Herculean hand strength.

Both Ed and Fred tried and failed to install our test pair
of Tufo Hi-Composite Carbon tubular clinchers (about $50
each). So I was given the task. Guess they figured my
Sicilian blood, strong hands (no, not from choking people,
although I've often been sorely tempted) and stubborn nature
would be the right mix to get those babies onto wheels.

Well, I did succeed, though not without summoning the grace
of the Madonna. I had sore thumbs for days. They were the
toughest-to-mount tires of any type that I've encountered.

Then I loaned the wheels to Duncan, a wonderful friend, to
test. Duncan is a fast recreational rider whose son is a junior
world MTB champion and an up-and-coming road phenom.

Duncan liked the Tufos' general road feel, calling it "silky."
He liked how well they held pressure between rides. But he
said they seemed sluggish cornering and accelerating
compared to real tubulars.

Tufos contain a puncture sealant, which Duncan termed "a
comforting addition, as was the feeling that no matter what
happened, these tires would stay put and could be ridden
flat." Still, he felt more confident carrying a conventional
tire, tube and rim strip -- not a small bundle -- in case of
a puncture.

Duncan wondered, as we all do at RBR, why do these tires
exist?

He felt they didn't ride as nice as good tubulars and no
better than good clinchers. He had the same titanic struggle
when mounting them on his own rims (and that's after 30
years of rock climbing, which builds strong hands 12 ways).

I did some work with the scale, just to verify a couple of
things.

The Tufo model we tried tipped at 385 grams (with sealant)
although the claimed weight is 335. A Michelin Pro Race
clincher with a light tube and rim strip totaled 320 grams.
You do the math.

Do we really need another tire system? And are these
particular tires worth the installation hassle if they weigh
more than good clinchers and perform no better?

I rode the Tufo S3 Lites for a year and have switched back to Continental Sprinter tubulars. The Tufo S3s felt like they had low rolling resistance but didn't feel as sure in a corner. They also weren't quite as smooth feeling as the Conti or Vitoria. A lot of what you here is perception and this was mine.
