This does me for 100k routes on the roadie, I don’t vary much throughout the seasons. I have this sorted down to a small and effective manageable pack which fits in my jersey pockets.
I add to that a Lezene multi tool if I’m on the CX’er.
If I get cold or hungry (unusual) I head for a cafe or small shop, if I run out of water (occasionally I do) I head for a shop or a church yard and seek out the tap.
Remote rides or 100k point to point roadie rides and I’ll take the multi tool too, debit card and another £50.
