I realise that there's probably another thread for this, and that it's pretty much a "How long is a piece of string?" question, but I'm wondering what other people would consider 'basic' tools for a tour. If our planned tour to Japan goes ahead, we'll be using the same reconditioned 90's era steel MTB's that we usually do. They are due for new tyres and we'll probably use Schwalbe Marathon Plus as I've been using those for years and not had any problems that were not self inflicted. Apart from this I'd carry pretty much the same as I do now: Spanners for removing wheels/pedals. Several hex keys because one set can't get at everything on the bike: 'L' shaped Hex key set Three way hex key set 4/5/6mm 'T' Hex key 5mm Crosshead screwdrivers Pump Puncture repair kit/tyre levers Spares: Cables V-Brake blocks What would you add?
