Park Tool Super Patches: TOTALLY USELESS.

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Park Tool Super Patches: TOTALLY USELESS.

At least, they're useless when you want to fix a road bike tire that inflates to 100 PSI. Won't hold pressure for longer than a minute before it either pops of develops a slow leak.

Yeah, glueless patches are a bit tougher to get to work 'right', and seem to always develop slow leaks. If you're popping them off, though, you're probably doing something wrong.

In my mind they aren't really a repair, more like a tube-band-aid to get you home.

They're not popping off. I fill the tire to 100 PSI, a few minutes later I hear a pop and the air hisses out. Afterwards, it no longer holds air.

The worst part is I bought two new tubes today, and BOTH of them broke on me. One exploded while I was filling it, the other got torn during installation for no reason.

I wouldn't trust this band-aid for a ride around the block, unless I kept it at about 60 PSI... which is too low for a road tire.

I've tried them also, with the exact same results. EXACT.

Old fashioned sand paper/glue/patch for me, thankyouverymuch.

FWIW, I bought some cheap pre-glued ones from performance bike, I have 3 on one tube and no problems at all.

You have to be careful about applying them, but I have some that have lasted for years. I don't try to patch on the road though. Use a spare tube for that, then patch at home where you can do a clean and careful job.

don't think you are supposed to pump them up to 100psi. they are there to get you to a LBS, bus stop, or home

I had some pre-glued patches that did exactly the same thing, covered the hole, inflated tire, went back to check and tire was flat. Thought to myself I must have missed a hole somewhere else, checked again, and sure enough slow leak out from under the patch, 3 patches later, I gave up and bought a new tube.

I'm not sure why everyone seems to have problems with these patches, but i think they're excellent if you prep the tube correctly and apply them to a dry tube.

i've had one of these patches on a tube in my bianchi for over 1000 trouble free miles, and i routinely inflate those tires to 120 psi.

strange that people have problems, though i could see them not working if they were applied to a damp tube, or the tube surface wasnt roughed up a bit with the sandpaper.

Was teaching a class the other night and part of the discussion was on patches... pre-glued patches are a band aid that will get you to where you can do a proper repair.

I don't carry them as applying a proper patch does not take much longer and if I am time challenged just swap in a new tube.

I don't ever have any trouble with the pre-glued patches. They work just fine and hold 120 psi. i have no idea why they don't work for you.

Are "Super Patches" the no glue type? Because I got some Park Tool patches with a glue bottle and I hope they're not going to "pop off."

Had the same problem with the park patch as well. I'm thinking i didn't buff enough maybe for the patch to really stick. I had to patch on the road and it was good enough to get me back home but my tire was flat the next day. i took out the tube and saw a large bubble where the patch was... I'm going to try glue based ones, but it might have just been user error.

If they really do suck then i'm just going to use them for ppl who are in need out on the road

I just buy a bunch of tubes when they are on sale at PBK, etc. for $4 or so and never screw around with patches anymore. It isn't worth the hassle.

The patches worked fine on a hybrid tire that I patched, since it's only filled to 65.

And yes, I dried and sandpapered the damn tube.

Sounds like operator error in all 3 instances. The exploded tube in all probability means that the tire wasn't seated; the torn in installation shouldn't happen, particularly if you don't use tire irons, or are careful with them if you must.

So telling us you destroyed 2 tubes due to operator error, doesn't instill a lot of confidence you put the patch on correctly.

Those pre-glued patches when they get hot don't work well.
I've had some that worked just fine but I also ended up walking home because the others would not stick.
I won't use them anymore,for now on I'll just glue on regular patches I've never had them fail.

I've found that you have to get all the air out of that section and lay it flat so that the patch expands at the same rate as the tube. patching it with any air inside lets bubbles form under it. They also seem to work better on hole type punctures rather than slash type punctures (ie pinch flats)

Same for me, they work just fine. I think the Park ones are the best, but the others work too.

I think the difference may be in how they are applied. I stick the patch to a tube with NO air in it, and use my fingers and a round end of the tire iron to squeeze any bubbles out and press the patch firmly onto the tube. Then insert the tube and inflate. Don't stick the patch on and inflate the tube outside the tire. Not even a little bit to make the tube easier to install without pinching.

The only time I had a problem was when I didn't clean the tube enough.
