Wise man going for 2 man. With bike kit, you have to be v. small to fit into a 1 man tent.
As my tent is v. small (for a 2 man). I take a bike cover and leave luggage and non-valuable stuff on the bike, under the cover. Means more space in the tent. I see from your sig. you don't a fender extender. Best take a can of WD40 too then
Seriously though, a bit of duct tape is always handy (fixing tents, holding luggage down, broken fairings, etc.) don't take a whole roll as that is quite bulky, just take 'enough' re-rolled around a rectangle of plastic (old credit card/similar) or buy one of the small packs of it rolled like that. Camping pillow in a stuff sack is handy and a small camping bed is a surprisingly cheap/small luxury. My camping bed is a rip off of the old BA design and cost £8 in Argos. Although obviously a bit heavier than a foam roll mat, it actually packs physically smaller (and within reason, small size is more important than low weight when carrying stuff on a bike).
