Two Polish sayings apply here:
- A mountain gave birth to a mouse;
- Making a pitchfork out of a needle.
While I - being paranoiac a little -- would consider taking a chain breaker and a spare quick-link on a Gran Fondo ride -- and I would certainly not forget taking a spare inner tube, tyre levers and a pump. I might consider a first aid kit. And toilet paper as you never know...
...Yet it has never occurred to me to take a spare valve core on any ride
