I have a Trek 7100 (2006 model) equipped with fenders, headlight, tail light, rear rack, rear trunk/panniers, handlebar bag, multiple water bottle cages, etc. that I will use to ride the Great Allegheny Passage from Pittsburgh to Cumberland, MD (and possibly back). This "machine" is stock, but I have added the above extras, and a few others, to outfit it for touring (I realize there is far more to a touring bicycle that my bolt ons). However, I have done a few distance rides on this bike and so far it has served me well. Additionally, I am planning a day long 70 mile ride as a test run for GAP ride. I am very interested in touring but do not want to invest in a "true" touring bicylce yet. I am a fairly strong rider/runner/athele and also ride a mountain bike and a road bike. Does anyone have any thoughts/suggestions on using a Trek 7100, as outfitted above, for touring? Any other suggestions... Am I crazy, or is this possible?
