Thank you for all of the advise!
(very handy picture Patrick)
I think I am going to take the two long levers that I have and pack in the little short one as a third.
I have a spare tube, but only 1... Since I have 'sealed' my tyres, I'm hoping 1 is enough
(it's difficult to decide isn't it - all of this 'in case of' stuff - the more you pack, the less you'll need)
Gloves and soapy liquid at the ready too
Oh - forgot to mention lack of rim locks (for better or worse)
Definitely must remember to lower pressure in the sand!
Anyone fixed a puncture without removing the wheel
(don't worry - I don't plan on doing it this way, before you all get excited - it sounds like a neat trick)
If you don't have bugs in your teeth, you haven't been grinning enough!
