I have a 08 Trek FX 7.3 that has seen about 3k miles thus far and has been a joy for the most part. Thing is I am getting bored of riding on my own all the time and was thinking about riding with the local cycle club, well I ran into them a few weeks ago and well, I was not really able to hang with them as they were doing a steady 19mph, after about a mile my legs were not happy and I had to drop back to my 15mph normal pace. My riding is almost all road or bike path so really the hybrid rout may not have been the best path for me, guess I should have looked around more before I got the FX 7.3.
Now the what I have been wondering is, is this bike suitable for such rides via upgrades, fork, bars, tires etc. or should I just get a Trek Series 1, or Specialized Allez*. I know what my biggest problem is, is the uprightness of my riding position, I was hoping that lower road cycling bars would help this. I have seen others suggest putting 700x25 tires on my bike in place of 700x38's it currently has. Others have suggested a road cycle fork for the more aggressive angle to drop the bike more.
*I am looking at these bikes as I have been told by both of the store guys that my 220lb weight isn't the best for carbon frames, losing weight isn't an option with my stocky 6' build, I am actually at my lightest in years.
