**** rule 30 and carry a decent pump. I use a Road Morph, but even that fits in my pocket (even if it as long as my back)
It’s been used on every occasion a club rider had a puncture, it’s known as the ‘club pump’
Failing that a mini pump and a re-sealable Co2 to top up with.
Never seen a mini pump perform up to 100psi yet.
Whilst on this subject, I think there’s another c*** of a rule about tube lockrings and valve caps. First of all WTF 😯 secondly I suggest at least fitting one lockring to one of your tubes. Other wise you pump is going to be wiggling that valve about until it snaps off. And a cap can hold some air in a terminally damaged tube.
