Forum | absence of a 10mm spanner ?

What ho chaps ,

 I may have bats in my belfry, but i was pondering the absence of a 10mm spanner from the freebie bag ,

there is a very nice king dick of adequate proportions to remove the wheels BUT there is the small matter of the 10 mm rear brake arm bolt .

 I realise you can sort out a puncture without removeing the wheel but that must be a real faff if it is not obvious like a nail or similar, but the supply a spare tube ?

 Yours, new to this “old tech”
