Strengths: The frame is a really comfy ride. I'm also really happy with the wheels. The fork absorbs a good amount of road vibration.
Weaknesses: DO NOT WAIT TO DUMP THE TIRES! The conti's are really aweful. I changed after 2 rides to michelin pro race, and have been REALLY happy with them. Thats my biggest complaint about the bike. Other than that, I would like to change the front derraileur someday...but not a big deal. I would also like carbon aero bars, but again...not really a huge problem.
Bottom Line:
This bike is an awesome mix of good price (at msrp) and great ride. Its nice and fast and a really comfortable ride. I've put a good number of miles on it and continue to love it. Not only does it work great, but I constantly get compliments on what a good looking bike it is. Derailleurs are good but not the best. I will get around to dumping the front 105 one of these days..but since it's not terribly important, it's not really at the top of my list of priorities. Overall, I LOVE THIS BIKE!
