Stopping punctures, is this a bonkers idea?

When I first read this, I thougth that is nuts, but then thinking about it, it sounds very doable.
Take your innertube, and with a stanley knife cut a small slit, use a plastic sringe to inject Stans notubes (tubeless) fluid. Repair the hole you have just cut in the tube with a conventional patch. Voila puncture proof innertube, well in theory.
anyone tried this?
results?
is it bonkers?
BullS#!+?
or brilliant?

...or just buy 'green slime' tubes?

Do many tubes have extractable valves?!Giant Reign - now sold :-(

Presta Valves, so no option for valve extraction.0

3 punctures in 3 days suggests:
underinflated tyres
worn out tyres
cheap and nasty (or Continental) tyres
rim tape not working
puncturing foreign body still in tyre
pinching tube when fitting
poor fitting of tube
With good tyres and tubes and correct fitting and an eye on the tyre pressures I get zero punctures on-road. Slime won't prevent punctures, it will just conceal them for later "use".0 -
+1 for all the above.
Except the continental comment, they rock!0 -

That's nothing, I got three in one.... Freezing cold, pitch black and in a hurry home - hissssssss (one).
Off comes wheel/tyre, found the glass, in goes spare tube. Back on bike and pump it up. Then, having got it up to pressure, I remove the pump......Hissssss the valve blows out (two).
So now I'm stuck, no spare, miles from anywhere. Just about to start walking when I remember the little pack of Park self-adhesive patches I carry for emergencies.
So off comes wheel/tyre, on goes patch, back on bike etc etc. Remove pump.....hissss. It's pitch black and I've put the patch half an inch to the left of where it's supposed to be (three).
Bit late home that night, and now carry two spare tubes.0 -
That stuff looks fantastic.

It does look impressive.
I was expecting him to stab his hand though. Maybe I have watched too many "you've been framed" type videos... :twisted:
I suppose punctures are more prevalent at this time of year due to wet roads acting as lube for the foreign objects to work their way in.0 -
Punctures? What are they?
I'm really going to regret posting this. :shock:0 -
or just buy a pair of these, indestructable but very likely to eat several innertubes while putting them on

Good quality tyres (costing around the £30 mark) in good condition, at max pressure, and avoid riding over sharp edged potholes if you can at all avoid it, if not take you weight off the saddle.
Punctures will be minimal.
As for the guy with 3 flats in an evening...had 2 in an evening a couple of weeks ago. Late enough getting home as I had to pick up club kit from a few miles away in the other direction, halfway home and hit a pothole I well know about but couldn't avoid as I was being overtaken at the that point. New it was going to be a flat before I knew for sure.
Stop under street lighst to fix, ring the missus and say I'll be late, thrugh leg over bike and find out tyre is flat again! Find that a small tear at the base of the valve of my spare has allowed just enough air in to convince me it was fixed without being enough to last more than a few minutes. Change tube again with my 2nd spare and set off, air temp near freezing and getting colder by the moment.
Club mate on a recent club run managed to get 2 pinch flats at the same time, front and rear, only had one tube! Not worth the risk, easy to carry a couple of spares, and better than walking 7-8 miles home or to a railway station, so now carry 4 spare tubes (3 in pack and one in back pack) just in case...having had a couple of commutes where the PF visited 3 times I know it will pay off in the end.'Twas Mulga Bill, from Eaglehawk, that caught the cycling craze....0 -
I find that cheap training tires are good for keeping the fairy away 23mm blizzards etc still reasonably quick but tough enough to cope with wet muddy gritty lanes.0
