>>1477866For the weight, I learned that if you have the space, you tend to bring a lot of stuff that you don't really need or use, and that means dead weight. So I try to make my load-out to ~10kg of gear and clothes and that's it.
P.S. if you have a simple handle bar and can't change hand positions, buy some cheap padded cycling gloves, hands start to hurt like mad afters days of riding,
