Maybe they've gotten better, but I've had no luck with glueless patches on
road bikes. Every one that I ever used eventually pulled loose and leaked.
Some took a few days to fail, others a few weeks. I don't use them anymore,
but I do keep some in my seat pack in case of emergencies as a backup to a
backup to a backup. Spare tube for first flat, then patch kit for the next
few, glueless patches after that.

The last time this question came up, some mtb'ers said they work just fine,
possibly because of the lower tire pressures.

Riding on with glue only,

Yes. They are about as much use as a chocolate teapot. I carry spare
tubes and Rema Tip-Top patches, which are quick enough not to be an
issue.

On the other hand the lowest pressure at which I run tyres is 80psi.
40psi MTB tyres might well be OK with glueless patches as a
get-you-home.

Yes, thousands of pepole have had this problem. That's why glueless
patches are a loser product.

Yes, this is to be expected with glueless patches.

Good luck. My advice is to buy a proper patch kit for three bucks.

I don't know that much about them but I thought they were supposed to
only be temporary, a patch to get you home. Then you put on a
permanant, glue on.

Occasionally, but the biggest problem with them IMHO is that the tub is toast
once one peels off. The goop it leaves behind can't be removed enough to put
on a "real" patch and subsequent glueless patches don't seem to hold on it.

Trash the tube and switch to glueable patches.

There is the frozen glue problem; and the too-old glue problem, this in areas
where you don't get many flats and so your glue expires by the time you need it.

And, with modern tubes, the damn-glue-doesn't-work-anyway problem.

This is all solved by carrying an extra tube. You need one as a hedge
against a blowout with or without a patch kit.

There's also the opposite school, which is mine at the moment, that flats
are rare enough on commutes that it just presents an opportunity to walk home
one day instead, and to hell with the toolkit entirely.

Why bother? Like the man says, it's not like ordinary patches are
hard.

Yep, that's me. Never had a single flat since I switched to MTBs 3
years ago. I commute 11 miles daily year round, soon to be 17-18
miles. I carry no patch kit, no tubes and no pump. I don't even know
where my patch kit is anymore. It probably wouldn't do me any good in
0F temperatures anyway.

The first time I used glueless, I had a horrific experience. After having
some very nice mechanics help me air my patched tube 100 psi, it only held
air for 10 minutes. Approx. eight o'clock that morning I gave up and waited
in front of a bike shop until they opened. I bought a new tube. My first
time was also my last. Back to using REMA 'glueful' patches and these still
work as advertised. Good stuff. Glueless patches elimate the need to carry
a little tube of rubber cement but how great of an inconvience is this
anyway?

In my limited experience, they're almost as reliable as a spammer's
money-back guarantee. I tried three different brands, had no luck,
and *then* I asked the guy at the nearest lbs which ones he
recommended, if any. He said that he'd never found any that worked,
not even well enough to get him home on a short ride.

Putting a regular patch on the tube where a glueless one has left
traces of its adhesive may make the regular one fail to hold, though.
At least, that seems to be what happened to me on the one occasion
when a glueless patch managed to work just barely well enough to get
me home.

To get be your way as quickly as possible when you don't mind taking a
risk and have to spend as little time as possible - or when you've
lost/forgotten your glue or it's dried up or run out. An emergency, in
other words. When it's obvious where the puncture is located, there is no
faster repair. Whip off just that bit of tyre, slap on a glueless patch,
etc. That is faster than changing a tube or anything else.

They are slower to apply.

Yes, but I've also had success on other occasions with Giyo gluless
patches at 130psi. They tend to be more reliable in dry conditions, but
still best saved for emergencies only, and then replaced promptly with a
proper patch. Carry some but only in addition to a normal puncture repair
kit (and spare tube).

True enough - many of the problems of glueless patches may go away if
you prepare the tube properly first (i.e. clean and abrade it) - but
since that's 90% of the work of a proper patch, you might as well get
the glue out ;-)

They won't hold at road pressure (100 PSI) - they'll get you home, but
aren't a definitive fix. They will hold at MTB pressures (40 PSI). Not
worth it for road use, IMHO.

Lou D'Amelio

Glueless patches have a reputation for poor seal. They might be good
to get you home, but properly applied glue patch is likely stronger.
Addressing your own problem, you could try cleaning the tube off very
well before applying the glueless patch.
Don't pre-inflate the tube before fitting it on the rim. Maybe the
inside of the tire can hold the patch in place.

90% of the work of proper patching is waiting for the cement to dry before
sticking patch on. Then there's the backing celophane/paper to carefully
remove. Only takes seconds to sand tube and apply glueless patch.

I don't really count sitting waiting as work. But whatever.
