I find my Trek mountain/hybrid to be extremely uncomfortable to ride for a long time. The front end is way too low for comfort, even with raised handlebars. I'm going to see if I can find a very long stem or handlebars that come up a lot farther (sissy bars?).

Where do you find racks for your bike that can handle 65 lbs? I have trouble finding a rack that can hold anything bigger than a basketball...
