I need a bike I can commute to work with, 25 miles one way, but I can cut my commute miles by climbing a fireroad through local east bay park. So, I need a bike I can ride on and off road. With that said, I think I would like to do some 2 to 3 day local touring. I really like the 29er or 700cc size wheels and the disc brakes that the Fargo offers. Plus when I commute I like saddle bags over backpacks. I am used to riding my mt. bike 10 to 15 miles to get to dirt trails, so fat piggy tires do not bother me that much.. Do I need a cross bike? or rigid 29er or Fargo, or ???????
