Trek 520 - Kona Sutra - Surly LHT. I tour with a Trek 520 loaded front & back with 40 lbs. of gear and it`s the Sh**ts when your on a bike that is not designed to carry that. I did it once on a Cannondale Synapse Sport on never again. When you start descending down a long hill, i.e the Oregon Coast hills, that`s the real test as to weather your bike can handle the wieght or not and it`s scary when it can`t. I would buy a real touring bike and sell it after the trip if I had to. Just my opinion. Good luck.
