My whole day out was grand, but for the sake of 30 quids worth of bits under the seat, I could have spent the day waiting for the AA to get me home.
As the Boy Scouts say 'Be Prepared'
Sorry need to disagree 100%
I've seen so many cheap arsed tyre repair kits go wrong, and end up needing a new tyre anyway and the solution? DON'T use the AA, use the RAC instead, they are far more bike orientated and friendly. They repair punctures and the fix is life of the tyre and done by a professional.
So I lose a bit of time but if my attempt to repair, the puncture goes wrong then I'll be forced to call the RAC anyways who may condemn my repair and recover my bike home, so day is lost and new tyre needed. Instead of hour and a half lost including repair and back on the road without another thought.
PS: The AA are tossers when it comes to bikes in many of my friends experiences, the RAC are excellent
EDIT: PPS If I did the repair, I don't think I would settle down and forget all bout it afterwards worrying it was leaking so for peace of mind and considering I am riding in the UK I'll get proffesional assistance that I pay for each an every year. If going to Europe? Then I would invest in a puncture kit and pump as you suggest just in case the local morons won't repair
