why we do it

don’t feel deflated… here’s the bicycology guide to puncture repair

1. First part the brakes. Press the valve to deflate the tube a bit
2. Lever the tyre off. You don’t need to take the wheel off unless it’s a slow puncture. Push the inner tube out.
3. Inflate and listen for the air (if you can’t hear it, use a bowl of water and look for bubbles)
4. Use a pen or chalk to mark the hole. Deflate the tube again before sandpapering an area just bigger than the patch (this helps the glue to stick)
5. Apply glue to the tube and wait till it looks dry before pealing the foil or paper from the patch and putting it on newly revealed side down. Or...
6. If you‘re using a self-adhesive patch just apply it. Press down patch firmly with thumb and use chalk or dust to stop any exposed glue sticking to the tyre.
7. Check inside of tyre gently with fingers, for glass, thorns etc Tuck innertube back in.
8. Starting at the valve use fingers to push the tyre back on. Check tube is not trapped between edge of tyre and wheel. Reattach brakes…
9. Pump up hard – it helps prevent punctures. SOFT TYRES = MORE PUNTURES
