Hey all Happy Holidays. Here is my dilema. I have a 2001 cannondale caad5 full ultegra r2000si road bike with mavic kysrium ssc wheel set. The bike is in good condition and run well. I was wondering if It is worth ugrading to a caad10 road bike with rival or 105 groupset. How much more performance can I expect from the caad10. Also how much better is the latest rival and 105 components to old school ultegra. How does my old ssc wheelset compare to modern day entry level wheels.
