This is my first post, so be gentle...
I am riding on a mountain bike - TREK 4300 '10. Started over a month ago, and really enjoying it.
Currently I am riding roads more then trails, to get in a better shape then I have started (~300lbs).
From reading the forum I have noticed more people are riding road bikes then mountain bikes.
Is this for a reason related to weight or just the selection which more people are doing?
