>>1998105That looks like a Darren Alff setup, sad to hear that he quit bike touring.
But as everyone said, don't place all your weight on the back. I had some "ultralight" gear, e.g.: tent, sleep system, clothes, that weighed relatively little.
The front panniers had all my tools, food and cooking stuff. My handlebar panniers contained my valuables and electronics.
As someone pointed out in a different thread, yeah the bike handled like a pig but I was surprised after a few kms that everything just "settled in", you get much fitter as well.
As for wheels, I invested in a set of Ryde Sputniks with 36 double-butted spokes. It's as strong as they get for that size. I remember hitting severe potholes, curbs, rail lines, etc... these are tough AF.
How long are you going for?
