What do you need?
Well some have been using Rack and panniers but those bumpy trails can cause havoc so i am looking at a seat bag system
teamed with a handlebar roll
and then some lightweight things in the Camelbak like a down jacket for when stopped and maybe the down sleeping bag. 1.2 kilo total
Also looking at a frame bag but won’t get that just yet until i try out the other two systems.
Or you could go crazy as BA said ‘like these foools …’
