Well then let’s count em’
Handwarmers (the shake and break type) simple things and easy to use, used to use these racing Yachts when it turned chilly..these really help if you have to fix something or mend a sodding puncture.
2 spare tubes, saves time arsing around mending punctures.
Park multi tool thingumybobs, that I’ve yet to use in anger.
2 gels
2 bars (though these have been in since July so I’m asking for hardened teeth breaking solidity)
Pump
4 air canisters and the valve thingy.
1 tyre lever.
1 puncture repair kit with about 15 patches and 2 glues.
And a Waitrose plastic bag for it all to go in, then placed in the middle pack of my camelbak.
