Puncture Repair Kits

[Marchrider]

in the same way we have kits to fix punctures on cars that don't carry a spare tyre - pour in some gunge then blow the tyre up.
Is there anything similar for bikes - a roadside repair kit rather than having the stuff in there permanently. (I have let my rear tyre down to remove it from bike)

This will work, but you have to carry a large single use can around with you, fine if you have a pannier but it's still only useful for one hit, so not good from a redundancy perspective.

I carry one of those cartridges that @si_c linked when out on my Brompton as I have nightmares about having to remove the rear wheel at the roadside. I've never used it tho.

It's also possible, if you know exactly where the puncture is, to keep the wheel in situ, unseat the tyre at that location, extract the right bit of tube and patch it. I've never done that either

Did that with my first ebike - because getting the wheel off was almost impossible

Did it once in the middle of a forest and the puncture was obvious as there was a thorn right through the tyre -
once I couldn't find the hole so I took the tyre off the rim and fiddled the tube down so I could put it in a bucket of water to find the hole

worked OK
but after that I tended to try to remove the tube off the non electrical side of the motor

I don't think I want one of those cartridges, I was more thinking of a small bottle of what is used to temp fix car tyres, I can soon blow it up myself.
if i decanted 15ml out of the bottle in the car into a small bottle/container. then somehow got that through the presta valve ?
does this stuff go-off as soon as it is exposed to air?, would I render both bottles useless by doing this ?

and does this stuff work when its cold, like 1 or 2 above.

I suppose you could get a small bottle of tubeless sealant. 50 or 60 ml or something. Like this: https://www.merlincycles.com/stans-tubeless-tyre-sealant-60ml-312956.html When you have a puncture you could remove the valve core (provided your valves have removable cores, of course), and squeeze sealant from the bottle into the tube and replace the core. All theoretically possible but I have no idea if it would work. For small punctures I Imagine it would. But I suspeclt it would ruin your tube and it would need replacing once the emergency was over.

Slime do some sealant which you can put into your inner tube in advance of a puncture to repair it or pre-slimed inner tubes. I presume they work well enough as some people swear by them but to my mind they combine the worst elements of both tubeless and tubed inner tubes you get all of the mess and all of the extra weight and higher tyre pressures. You could try using it post puncture but most of them seem to be intended for use as a preventative.

I've not spent too much time looking at this sort of stuff though as I run tubeless on one bike which has given me no puncture since and I'm really happy with, but for my winter bike I just carry a few spare inner tubes.

Spare tubes and patches for me. I saw the mess made when a gunk/slime/whatever filled tube gave up on A N Other's bike.

Yeah that's my thinking, I'm happy with tubeless where the gunk and mess is a known and where a puncture which causes that to fail compleyely likely means the tyre is also shot or tubes where the mess is down to how dirty my hands get taking the tyre off. I wouldn't want to rely on putting gunk into a tube and then hoping it seals versus a patch/new tube.

I've used these Park Tools Pre-Glued Super Patch Kit in the past.

Thinking about it, I did once try dumping regular tubeless sealant into an inner tube. I'd cycled to some friends' and they asked me to take a look at a wheelbarrow with a flat. It had a Schrader valve so I removed the core and squirted in pretty much all if a 60ml bottle of sealant. It seemed to work but I don't know how long for.

I think the best cure for a fear of punctures is a period like I had about 25 years ago, when I got plagued by so many I just wasn't fazed by them any more. My priorities are not gunging up the valve/pump with slime, and not using up my only spare tube unnecessarily in case I get more than one puncture, or a puncture I can't patch in the pouring rain. (I never did get one in the rain, horizontal snow yes, rain no.)

It's also possible, if you know exactly where the puncture is, to keep the wheel in situ, unseat the tyre at that location, extract the right bit of tube and patch it. I've never done that either

I did all mine that way until my sight and hearing deteriorated to the point that I couldn't find them anymore.

That reminds me that I did do the sealant into a wheelbarrow wheel once when I first met my now-wife

I am pretty sure it would work with a puncture on the road
only problem is that I have bad experiences with pre-glued patches
I have used them and they have worked fine
then a few days later the tyre goes flat again and it turns out that the air is getting out round the side of the patch
seems like teh glue was not as good as I was hoping!

AT the end of the day it is easier than trying to put rubber solution on , then waiting for it to dry, then putting normal patch on as "normal"
but long term I have never had it work

Having said which - I have had loads of problem recently (i.e. for many years ) getting deents normal patches
the ones in the "puncture repair kits" are just fine - but the replacement are rubbish and tend to rip and all sorts

I often just get fed up and get a new tube

I’ve only ever had one puncture on my Brompton, I folded it up and caught a bus home.
