This little piece of handy knowledge will get you out of a tight spot if you don’t happen to have a puncture repair kit (or a new tube) to hand. The video is pretty weird but it’s a rather handy video that I think should be watched by anyone who rides a bike really… Totally felt like kicking myself after watching this, I’ve had to push my bike for miles in the past and if I’d of known this little trick, it could of saved a lot of time & effort!
