Just found out on inspection of my bike that the lower headset race (on the top of the fork crown) has a hairline crack. I therefore need my LBS to replace the entire headset. The HS is Dura Ace and I has found that an online price is around $80. I understand that I should expect to pay more for local service but what should I expect to pay for the headset and how much for labor? I know that I *could* install it myself, but I have already made the decision to have a pro do it simply because I dont have the tools and don't want to screw up a good Pinarello Opera frame.
