Hi guys.. Iam in need of some advice if you would be so kind. Currently i have a desent carbon road bike with full 105 groupset(10speed) the model before the newest but did some miles with it as to date,but there is nothing wrong with them,they work perfectly. My wheels are the shimano WHR 550 standard factory wheels. Iam considering to upgrade my wheels to something in the area of 4000-5000.The make is not that important. But i also can get a full dura ace groupset brand new for a simmilar price. What is more important to upgrade would you recon? Thanx
