I am new to mountian biking, looking for my first bike "made" for the trails. I have been looking at Trek 4300 ('09 model) but just found a bike shop selling a Specialized f7 ('08 model) for about the same price. He states it is the same bike essentially... any ideas? btw, the Trek is going for $410 on sale and the f7 is $399 on clearance. I'll be riding (eventually) at Fort Custer and Yankee Springs in Michigan if you are familiar with them.
