Here is a lost of essential kit. I'll build it up as I go.

- Zéfal Glueless Patches are so much easier to use to patch punctures in an emergency. Ideally you'd always have a spare inner tube on you, but that's not always practical! Not needing glue also means that you don't have that horrible the glue's dried out by the time you need it moment ever again. I've had one of these patches on an inner for as long as I can remember! They're not always permanent but can be if done right.
- Schwalbe Tyre Levers are far easier to use than the ones you'll usually find - the last thing you want when you've got a puncture is more stress! I should mention that the design has changed since I bought a set but with any luck they'll be even better!
