A good tip on the GCN YouTube channel

What if the puncture is near the valve?

You have a bumpy ride home or walk.

Did anyone actually watch the video? He cuts the tube in half at the puncture, and then knots each end.

He does two different fixes. Cutting is for a big hole in the tire.

Ah - maybe I should have watched all of it as well!!

Having said that, it's pretty clear how he ties the knot, as you can see the preparatory work before it goes out of shot.

 

[Crackle]

That's quite possibly one of the barmiest tips I've ever seen. Good luck in making it work when you've got an actual puncture and it isn't conveniently on the opposite side to the valve.

 

[Vantage]

I can't think of any reason why anyone would ever need to do that other than having been so stupid to have not packed enough spare tubes and patches to cover that eventuality.

 

[Smokin Joe]

Thinking about that, a couple of cable ties pulled really tight either side of the hole would probably do the job too. Mind you, if you're the type to forget a spare tube you'd never remember to take the cable ties with you.

Though you could always use your socks as emergency tourniquets. Which wouldn't be much good if your pump was sitting on your workbench next to the tube and the cable ties.

Actually he does three.

Filling the tyre with grass is not something I would consider doing, ever.

Or are we just used to people being large?

Nope, he's a skinny fecker.

What does one cut the tube with? Surely a spare tube velcro'd under the seat is not more hardship to carry than a knife or scissors?

maybe you misunderstand the concept of 'if you have no spare'? some people carry a multi-tool which might have a blade. As for a hole near the valve... in my experience, a repair kit isn't much use either.

 

[Drago]

I didn't misunderstand it. Who forgets to pack an inner tube but remembers to pack a multi tool, pump/CO2 inflator, and tyre levers? It just seems unlikely someone would have all that and not a tube or patches. Its like dragging a picnic hamper and all the trimmings around, but not the sandwiches.

BTW, I would just like to say that I don't think this is a "good tip". Maybe if you were crossing a desert with no houses and little traffic, no mobile signal and you are running low on water, then yes, having a way to eke a few more miles out of your last shredded tube might make sense . But in the uk, take an extra tube, and some scab patches, then the chances of 2 of the 3 tubes being damaged beyond repair is so vanishingly small that it would happen less than once in a lifetime (especially if you take the sensible precaution of stopping at the next LBS/Halfords/Wilco etc to replace the first destroyed tube if it happens while the shops are open). In that extreme event, phone for help, call a minicab or Uber, walk to the nearest town, find shelter in a bus stop until morning, knock on a door, flag down a car.

He cuts it on the chainring.

 

[derrick]

What GCN didn't show was, how do you tie a knot in continuous ring (the tube) without putting a loop in it and thereby making it too small to go back on the rim?

It's rubber it will stretch

Has anyone transcribed the entire clip just for Drago?

Come on lads, keep up!
