I am getting back into biking and am curious as to what size frame to get I am 6' 3" as the guy that just posted and I am interestead in a hybrid bike and the Trek 7100 seems to fit the style and the bill anyone with some knowledge please share Your thoughts and suggestions 20" versus 22.5" frame. Is it more sturdy to have a smaller frame 20" or is the 22.5" just as sturdy what is the advantage with a 22.5 frame. The Kid at the Bike shop was not very informative and I dont want to rush in with out more knowledge. Thanks
