For me, it is a lot of the same as others have listed.
For my shorter rides, I have;
- 2 tpu tubes
- Patch kit(pre glued)
- tyre boots(park tool patches)
- Multi tool (Daysaver)
- chain breaker
- tyre levers
- power link
I also have a pump attached to the frame.
On a long ride, I will add a café lock and a mech hanger at least, usually I throw in a 3rd tpu tube to my top tube bag.
I used to swear on co2 right up until I got a series of punctures, and not enough co2s. I now just take them in the winter alongside the pump. Just so I can reduce standing around in the wet. And if you're taking 3 or 4 co2s, probably weighs close to a normal small pump at that point, but takes more space.
