I'm new to biking, and I plan to ride across America this summer. I know very little about bikes.
The guy at the bike place I went to really pushed a Tri-cross. I'll be taking about 50-60 pounds with me. I told him I wanted to research it online, but I don't see much about loaded touring on one anywhere. Does anyone have any advice or recommendations?
Assuming you are referring to this bike:
Its not a loaded touring bike for carrying 50-60 pounds in panniers. Its a cyclocross bike, sort of. Its probably fine for pulling a trailer.
I believe there are articles on the Adventure Cycling website discussing touring bikes and what to get for a cross country bike ride. And some webstie called crazy guy on a bike or something like that has many articles about people who rode all over the world. I suspect many of these stories talk about the bikes and bags and trailers the people used.
