Thanks so much for the great replies!
I am going to give this some serious thought about upgrading the Eddie Merckx or Cannondale vs. buying new. I think the new tire technology is the thing I really need to learn about. The Cannondale can take some pretty wide tires since it is designed for fenders and loaded touring. Right now it is 25pounds but I could lighten components a bit and probably upgrade wheels. The Eddie Merckx either needs better sizing for me or I need to get more flexible.
At the same time looks like I need to do some test rides of the new bikes too!
Once I hit 10 posts I can send some pics of them.
Thanks again,
George
