Tufo installation

How does one go about fitting one of those tubular

clincher tires on to a rim? I sent close to an hour

the other night with no success. Contis are tough.

These seem nearly impossible. What little secret am

I missing?

I stretched mine first, like a tubular. Step in the tire and pull it
over your knee.

Then put about five psi in it and start at the valve. Get the tire
(very) roughly on the rim all around. Next go around and work one bead
under the hook all around one side of the rim. So far this should go
fairly easily.

For me this next bit was the tricky part. Pinch the sidewalls together
to get the second bead under the rim's other hook. Work it in, inch by
inch, all around the rim.

Inflate and ride!

Thank you. I'll give it a try.

Ok, so I Googled Tufo. I've never _ever_ ridden anything but a
clincher, and I've always been 'fraid to ever ride a tubular type
because of the repair issues (I'm good at patching and being able to
mount clinchers with my bare hands...can't do that with tubulars)

Tufo has a sealant. My experience with Slime filled tubes has never
been good, and my conclusion about Slime has been that it's a smelly
marketing gimmick and practical joke to play on the mechanic at the LBS:
to fill his work area with the wonderful smell of chum.

From their FAQ page, Tufo tubular clinchers look unrepairable. Is it
safe to depend on the sealant? Does it actually work? Is it better
than Slime? Is it stinky like Slime? Do you wind up throwing away the
tire if punctured with a bit of glass?

Tufo sealant does work, and with relatively small amounts. The most
marginal case in my experience was where there was a big enough hole in
the casing that the Tufo sealant would leak when I pumped up the tire.
Once I started moving, it would seal, but obviously this is not
optimal. In other cases it has sealed latex-tubed tires better than
new- they actually lose less air now than they did when I first mounted
them. I think that it is definitely preferable to opening a sewup to
repair it, but it has its limitations.

The problem with those limitations is that there is no backup with the
Tufo tubeless tires, since you can't open them to repair them.

What is the reason again for tubular clinchers? It seems like the worst
of both worlds.

Huh? Of course you can mount a tubular with your bare hands. In fact, I
never used any tools to mount a tubular -- bad idea to do so, IMO, since
you might damage the tire. Be sure the tire is pre-stretched and it
should mount easily. How fanatical you are about glue will determine how
easily it unmounts.

My belief as well.

Certainly if you get a large cut in the tire, you'd have to throw it away.
But it seems that lots of folks who ride tubulars do that anyway. Maybe
they have more money than I did. I always repaired them until the cord
showed through the tread, if I could. I would not have much faith in
fixing a flat with sealant.

I have not tried Tufo, either mount style. But I think it's a very
strange concept to make a tire that cannot be repaired, especially given
my experience with tubulars and flats.

Dear Rec.SS and JP,

While Slime doesn't seem to seal large holes from nails and
glass chips, it often seals pinhole punctures, which are
common from goathead thorns--if the pinholes are in the
contact patch area, rather than higher up on the sidewall.

Or so it seemed to me when I heard the familiar
whoosh-whoosh-whoosh of a puncture a few days ago and found
a hissing goathead hole in my rear sidewall.

After I took the tire off to put in a new tube, I checked
and found two more small thorns embedded elsewhere that had
to be pushed out with a paper clip. They were easy to find
because the tube had not one but three damp patches of
Slime.

For people who rarely get pinhole flats, I doubt that
sealants are much use. Where goatheads thrive, they can seal
up to half a dozen punctures (the most that I've ever found
sealed after a seventh goathead stuck in the sidewall).

Nono, I meant _patching_ with my bare hands along with mounting. I
should have worded that better. You need a seam ripper (preferable to a
knife) and a needle and thread to re-sew the tubular, after you've
located the bad boy which can be difficult since you can't take out the
tube (that's how I find leaks anyway).

Mounting seems about the same difficulty as a clincher.

Well, it's not a strange concept if you're marketing to a disposable
society. I typically bike through what some people here call "inner
city" (Providence has a few rough areas, but they're nothing compared to
the corresponding areas of Hartford or Bridgeport), and the Tufo has me
scratching my head. I'd probably go through a pair a week.

On the FAQ page for Tufo, they say that clinchers are difficult to
mount. Last year I bought a pair of Vredestein clinchers. The guy at
the counter said that they were more difficult to mount than Contis.
Fine...I still mount and umount them barehanded. Maybe it's just me.

Oh, well, but you do that back at home.

Actually, a properly prepared tubular spare makes it quicker than changing
the tube of a clincher. Unless, as I said, you are paranoid about rim
glue as many seem to be on this NG.

Big, strong hands? But in reality some rims are easier to mount tires
onto than others. IMO that is more of an issue than the tire brand.

It's not the first (Wolber Liberté in the seventies, Soyo
Seamless in the eighties) but Tufo's system has been
embraced by enough riders to succeed. The great bulk of
tubular punctures seem to be small enough to seal with Tufo
sealer and complaints have been very few (One, here). I used
the sealer in a non-Tufo tubular ( one week old with a
staple in it) that has been reliably sealed for over a year.
