For a long time, I’ve felt it would be prudent to carry a puncture repair kit. I’d always been lucky enough to find my way to Burwin’s and have it done, but what if it was in the middle of nowhere?
So i found myself about to head out to work after the New Year break, all ready in the motorcycle clothing, and found that the bike was much heavier to wheel out of the garage. Further investigation found a nail in the rear tyre, and as the bike hadn’t been used, looks like a slow loss of air. It was icy out. Did i want to risk riding a flat to the petrol station to get air? And even then, it might only last part of my journey, and then I’d be even more stuck.
So i parked it back up, got changed, and drove to the underground. I couldn’t see any practical way of getting the tyre to a repair shop easily. And so I ordered myself a puncture repair kit from Amazon, with next day delivery (Prime) for £23.
- Storage case
- Reamer tool
- Hook tool
- 5x rubber strings
- 3x co2 16g canisters (plus a foam sleeve)
- Adaptor for co2 (plus a downsized possibly to fit a bicycle)
Points to note:
- There are no tools to help with object extraction, so you might want to ensure you have strong needle nose pliers and some prying tools onboard to help with that.
- The gas canisters are dirt cheap and can be picked up from most sports shops, Halfords etc in the cycling section. Order online. Make sure that they’re “threaded” like these: 20 x 16g Threaded CO2 Cartridge
So what you have to do is… remove the cause of the puncture – in my case, it was a screw embedded in there but no screw head. So it took a good amount of prying with a small flat bladed screw driver until i could get some purchase on it with pliers.
Then, use the reaming tool to enlarge the hole. Put some glue (doesn’t suggest how much) onto the reaming tool, insert the reaming tool into the hole in the same angle that the culprit had gone in, then drive it in and out constantly until the tool slides in and out without much pressure. This also roughens the surface so that the glue and string thing can bond. Note – if the hole isn’t large enough, you won’t get the string thing in.
Thread one piece of sticky string through the hook tool. It’s really sticky so try to avoid putting it down on, say, a dirty garage floor. Pass it through the eye of the hook tool until its middle. Then pull the 2 ends back towards the handle of the hook tool.
Muster all your strength, and push the hook tool straight into the hole at the same angle as the culprit and the reamer went in. Push it in until only about half of the string is still outside of the tyre. That’ll be about 1.5″ or so sticking out. Then, twist the handle 90degrees, and pull it straight back out of the tyre. The string will stay in.
Use the blade to trim off any excess.
Finally, grabbing the valve adaptor, turn the yellow valve clockwise (as you look at it) to close it, screw a co2 canister onto the adaptor, then connect the adaptor to your valve. Open the yellow turn valve and co2 will gloriously fill your tyre!
Actually, it won’t. You’ll use 3 of them. And then you’ll still want to stop at a petrol station to get it up to pressure. But it will get you to the petrol station. And you may have frozen your fingers too, so remember put the foam cover on the co2 canister.
Whole job took about 20 minutes, as i struggled with removing the screw.
