Hey all. I am looking to upgrade to a new bike..well used actually, but new to me. I am currently riding my Cannondale caad 2 F400. yikes I know right. I have about 1800.00 to spend. I mainly ride single track nothing too technical. I am 5'9 210lbs. What are your thoughts? Been looking at the Specialized fsr's, Cannondale rize 120/140, and a couple of the different Trek fuel models.
