What do I carry in mine?
- Puncture repair kit - for the obvious
- 13mm spanner - for wheel nuts and seat post
- Allen key - to fit gear levers, brake levers and handlebar stem
- Rag - to clean hands
- small phillips screwdriver - to remove chain case if necessary
- Couple of tyre levers
- Some cable ties - handy for tying back anything that comes loose
- Small amount of duck tape - just because!
That is perfectly fine for day to day riding. If I was touring I would probably add a spoke key and perhaps a wider range of allen keys and spanners for more serious tinkering.
