I got a slow puncture today midway through 120 miles, and it ruined my momentum for a while and pissed me off, and used up 3 of my co2 canisters 'cos the spare tube I had in my seatbag had a dodgy valve so I had to take it back out once I heard it hissing and puncture repair the punctured tube.
I completely and absolutely reserve my right to moan about this ****, and yes it's part of cycling and I am good at fixing this ****, but do I need to be happy that it happens......********** NO
