I’ve decided on carrying a plug kit and compressor as primary puncture repair (under seat and in toolbox) but I also have tyre levers hose clamped to the frame, and a puncture repair kit with valve tool and spare stems. If I’m going somewhere remote I will also pack spare tubes, just in case.
I did my first tyre change at home with (cheap knockoff copies of the motion pro) bead breakers and a 16” tyre iron, I think I should be able to manage it in a pinch with the 10” irons I have on the bike, but hopefully won’t need to.
