I currently ride a Trek Navigator 2.0 but would like to upgrade to a bike with a rigid fork and 700c wheels. The Trek has been a decent bike but I really dislike the suspension fork and twist shifters. My LBS only sells Trek. The Trek DS 8.1 is what I would buy if I stayed local. I can mail order a Diamondback Trace for slightly less money. It looks like it has the same drivetrain components plus disc brakes but I'd have no dealer support. If I drive an hour I can find a Raleigh dealer and get something like a Misceo. The base Misceo model has similar low end drivetrain components as the other two but has a cromoly fork vs. hi-ten on the other two. The Jamis Coda Sport looks really nice but I'm not sure if I can put wide tires like the previous three have. I'm 6'1" 330 lbs and have been riding about 10 miles a day on the Navigator on paved roads. Any advice or suggestions would be appreciated.
