As I did last Summer, I would like to ride 100 or so miles per week this Spring and Summer to lose some of this excess weight. My one and only century in October was memorable for two things: (1) I finished; and (2) I did so on some pretty horrible wheels after more than one spoke blew out along the way. The Trek 320 won't do it any more. Am I wrong in thinking that a touring bike--like a Trek 520--that is built for loaded touring will be a good solution that will allow me to spend more time on the bike and less time waiting for the wheels to be fixed? Thanks.
