Cheers for all the info so far.
Due to my bike having carbon forks, front panniers are a no-no. So my only storage points (at the moment) are two rear panniers, a bar bag, and the top of the rack.
I've been a few posts and it seems most people stash the tent (inner and fly) in the same pannier as the sleeping bag. I would have thought this would be a bad idea? Due to the fly often being wet, the inner's groundsheet being damp and coming in to contact with the sleeping bag? I could wedge both parts of the tent and sleeping bag in a pannier bag but thought separating them would be better.
My initial thoughts are:
Left pannier = Tent inner inside dry bag. Sleeping mat, in compression sack. Bits and bobs.
Right pannier = Clothes in dry bag.
Rack top = Sleeping bag in dry bag. Tent fly in mesh bag, tent pole in skinny bag.
Bar bag = wallet, phone, camera etc
Lunch time, the tent components would be pulled out to dry for an hour.
Is separating the tent parts worth the effort of having two separate bags? Should I just stuff the inner and fly together?
Any issues with this? I know dry bags aren't invulnerable but if it really lashes down I'll be getting off the road. The sleeping bag is synthetic btw, not down.
