I have a Cannondale R300 which I have been happy with thus far. It is equipped with Shimano RSX. However, after having read this forum and seeing the general consensus that RSX is fairly heavy and low quality, I am wondering about the value in upgrading the bike with new components such as 105 or Ultegra? Do you feel that this would be a waste of money and I would be beter off putting that money to a new bike? I'm on a fairly short leash, and its not likely that I would get the go ahead to spend big money on a new bike anytime soon.
I guess the bottom line question is whether the frame is worth the upgraded components?
Thanks for your input.
