Thanks for the responses so far.
Sorry just to be clear, this is a predominantly MTB trip. But we will be taking road bikes to ride a couple of Cols. (will be the first time on a road bike for me!)
Been to the Alps before on guided trips, but this is the first time driving down. Will be kipping in a van rather than 4 star luxury chalet.
Planning to do a different place everyday, so was just wondering whether there was any must have item for a week on the road (sleeping relatively rough) or invaluable piece of knowledge.
Planning on taking lot sof spares, as working on the assumption that any diversion to a bike shop could right off a whole days riding.
Might pack one of those solar showers.
