bike puncture

my first time at repairing a bike puncture...I don't know where to start, have you got any suggestions?

 

Have you got a set of tyre levers?

 

Yes,Slime Tube Sealant.Prevents and repairs flat tires on bikes,wheelbarrows and motorcycles

 

Ahh, the old "ask a question & then log out" trick eh?

Well, assuming you have & that you've got the inner tube off, inflate it & then use a bowl of water to locate the puncture. Dry the tube & roughen the area around the puncture with sand paper, apply the rubber cement to the area and wait for it to go cloudy, apply the patch & try to remove any cement thats not covered. Dust it with french chalk to stop it sticking. Keep it de flated till you've got the tyre back on. Make sure the innertube is not pinching anywhere before pumping up.

 

Spot on Zigs....

 

Exactly how I did it in the 60s Zigs

1) Don't assume you've only got one puncture, continue to check around the remainder of the tube.

2) Check around the inside of the tyre because if a tack, thorn, etc. is left projecting through you'll immediately get another another puncture.

 

When asking for a puncture repair kit from our elderly bike shop owner, he did say that a 'youth' had had one and came back as he had used all the patches but his tyre was still going down.


After interegation it turned out he was trying to stick the patches to the OUTSIDE of his TYRE!



Cheers, Tony.

 

tbh, its cheap enough to buy a couple of inner tubes these days. much less time consuming than repairing a puncture or 2.

 

Lets not rule out a failed valve. In my experience, this probably accounts for more than half of all 'punctures'.

To test for this, pump the tyre up (without even removing it from the bike), then spit on the end of your finger (less disgusting people using washing up liquid instead), then rub it on the end of the valve to make a film over it. If it sits there doing nothing, valve is good. If it blows bubbles or blows the spit/washing up liquid off, then the valve is bad. A bad valve can be swapped without taking anything off the bike, and depending on the type of valve, sometimes you don't even need any tools (a valve extractor will be needed if its the chunky car tyre type valves like you get on some mountain bikes).

 

much obliged, sir.
