I have the TREK 7100 and ride lightt dirt trails all the time around my place. I am careful about flats/none yet so far.I really need another mtn bike and I want a road bike too. One thing at a time for me. My trek 7100 has a suspension fork and a suspension seatpost. 2005 model you might consider this a comfort, I know I do :) Good luck on finding a bike. Sometimes the LBS may have a used model that someone traded up for. You can get a deal on a used bike that was taken care of.
