The only thing you have to carry on tour at our time of life, is a debit card, a credit card, some cash, and a change of clothes. And the change of clothes is optional.
As you may guess I'd rather eat worms than have to rely on a "sleeping mat", now there is an oxymoron, for a good night's sleep.
well you've got me thinking in a variety of ways and I'm going to order an Alpkit Stingray custom frame bag to give it a try. A rough measure of the triangle gives me 37x56x57 and opting for the 6cm width should give quite a bit of storage space. Two zips and a full length horizontal divider would allow tent poles, pegs and pump to go in top section and all my tools and spares in the bottom. I have a third bottle cage mount under the down tube but I also have proper bottle cage mounts on the forks as well.
I'm now wondering if I'll be able to manage:-
frame bag - tent poles/pegs, tools and spares - especially anything heavy
bar bag - documents and essentials - could also use a light Porteur style rack
bottles - x3 2 on the forks and one under DT
pannier 1 - cook stuff, tent and sleeping stuff - minus poles and pegs could this all fit into one 20l pannier? or would it be better to bungy a drysack with sleeping bag and mat across the top? or in front of the bars?
pannier 2 - clothes and electronics - netbook and kindle not sure on solar power yet as will have the front USB solution which is favouring the Luxus U right now
rack pack - Arkel Tailrider for layers, gloves, waterproofs, food/shopping and any odds and sods
I'm currently guesstimating 20kg of weight out the back including weight of rack and panniers/rackpack - so approx. 16kg of kit
