Good advice. I understand that the addict was designed to be light and thus everything that is not crucial is stripped, so I agree that cutting down on the stress on the rear triangle is a good idea. I have a hammock, summer sleeping bag, and a change of clothes + towel and soap to bring--not much. I can use my mtb seatpost to attach a seatpost rack to, would that be too much weight in the panniers? I'm 82kg so putting another 5ish kg shouldn't be too much, should it? I think in the end, I'll probably just get a rack that attaches to the skewers though...
Too bad about the trailer. I have read about others using trailers for carbon frames over long distances, but I haven't got the $$ to test it on my bike.
Thanks for the advice so far!
