I am wondering if it is a solvent glue like in the glue tube of a regular patch kit.
The solvent glue in a regular oatch glue creates a cohesive bond.
That is pretty hard to beat.

It's similar to adhesive tape glue, not like the "vulcanizing" fluid in patch kits.

I tested the glueless patches some years ago, and they leaked a few times. I really like the tiny size of the glueless patch box, but I don't trust them. I should do a series of them at home to decide if they are reliable enough to ride with.

I'll save my punctured tubes, and do 3 or 4 at a time, using a fresh patch kit and using up the glue in the kit. I trust these patched tubes -- I'll often have at least one patch on the tubes that I'm riding. I've never had one fail later, if it's good while pumped up for a day, it's good to go.

EDIT-- I don't like how unopened tubes of glue kept in my saddle bag can dry out. I suppose I could date them and swap them out after a year.

It's been years since I've needed more than my spare tube when riding. But you never know...

Is it not feasible to make a smaller container for the old school patches?
I am thinking a 1/3 sized container for the vulcanising glue itself and two or three patches in a very small box. I wonder what could be used as a glue container.

I never considered a different container. you could take a few patches and a tube of glue, throw them in a small ziplock, and it would take less space, and fit in more places in my saddle bag.


I carry Park self stick patches, just in case, but I'm not fond of them.

I too, carry Park self gluing patches, for emergencies. Usually, a spare tube and CO2 carts get me home. If that fails, I go to self gluing patches , but I would replace it with a regular patch at home. KB

I have a good tube with me.. swap it for the punctured one , then where its more comfortable than along the roadside,

like a aCafe or Pub, I take the time to do a proper patch, then that is my spare tube for the next incident.

+1. I do the same

Yeah, that's why I got rid of my glue kits and only carry self-adhesive patches.
Flat-resistant tires have meant very very few flats.
And glue tubes tended to glue themselves shut after being used once. Self-adhesive patches don't, and you can easily carry 5 or 6 of them rather than just 1 glue patch kit.

Try the Lezyne self sticking patches. I've used 'em for more than a year. They're outstanding.

For one thing they're nearly paper thin. No problems with the snuggest fitting road bike clinchers. When in doubt I'll double up on the patches, one on the tube, a second on the inside of the tire where the outer tread was cut but didn't penetrate the inner layer more than enough to cause a pinprick puncture.

The Lezyne kit is only slightly thicker than a credit card and half the size. The tiny plastic envelope holds the patches, metal scuffer and a tire boot for more serious cuts. It'll fit almost anywhere, even the tiniest saddle bag for the minimalists.

The patches are really tenacious. I've had one develop a slow leak after a few weeks. Just pumping up the tire put on enough pressure to seal the leak and I got home without needing to unmount the wheel or tire.

How tenacious? A couple of patches became slightly dislodged after several months in my saddlebag. One edge of a patch stuck to the inner plastic envelope. I could hardly tear it loose. A couple of patches stuck to each other. There was no way to separate them without tearing.

Since then I'm careful to be sure there's a flap of the slick paper backing between the patches and storage envelope so the patches don't migrate off the slick backing paper. Once those patches stick to any compatible plastic or rubber, they're pretty darned tenacious.

When I first began using the Lezyne self sticking patches in the autumn of 2016 I regarded them as temporary and intended to replace them ASAP with proper glued patches. And I did that for awhile. But life got busy and I forgot about some tubes patched with the Lezyne patches for many months. When I finally had a chance to inspect those tubes the Lezyne patches still held securely.

I still tend to favor the traditional glued patches for my hybrids. But for the road bike, once I've used a Lezyne patch I just leave it alone and don't mess with it unless or until the next flat. I got two flats in consecutive rides in November and have hardly had a chance to ride the road bike since then. When I pinch the tire it still feels pretty hard, probably around 80 psi or more, so it's holding air. I'll carry a new spare tube but otherwise I'll leave that tire alone.

Because I'll often double up on the patches -- one on the tube, a second inside the tire itself -- I tend to go through the Lezyne kits fairly quickly. I bought three of the Lezyne kits in early 2017 and have used nearly all of them, mostly on the hybrid that I ride on gravel, grass and rough roads with lots of broken glass. But I've used 'em on the road bike a few times as well. It's probably a good idea to replace any tire patch kit once a year anyway. Some conventional patch kits I've bought had dried up glue within a year even when the glue container seal had never been perforated or used. The Lezynes have held up better than that for me over the past approximately 14 months.
