Drastic Fit Change
 

Had a bike fit today from a respected bike fitter and my fit changed drastically. My seatpost went up 40mm and my bars dropped about 20. The new position doesn't need necessarily feel bad but definitely feels different. I was expecting a more comfortable fit. Would you adjust (thinking about lowering seat some) or ride for awhile?

You had your position dialed in by "a respected bike fitter" today and you are considering randomly messing about with your fit rather than adapting to the changes? :twitchy:

Did you respect your fitter as a fine human being but doubt his competence in bike fitting?

Go right ahead, change all contact points while you are at it.

Even by the best bike fitter, those are big changes.
Either give your self time to get used to it OR mark his settings, go some where in the middle & gradually change to his settings.
You body WILL need time to adapt

Is the goals they had in mind for you, ride like a road racer , low and fast,

compatible with what you will want to use the bike , for in your purposes..

It would appear you haven't had the road bike very long from your old posts, and was riding a straight bar bike before.
Give the new fit several rides it will seem very strange if the fitter had to move things around that much, and if you have any faith in the fitter give it a try, if after 10 good rides or so go back and tell him your issues and have him make some changes, you paid for a fitting so give it some time first.

I will suggest to try several 50-mile rides initially. The goal is to finish those rides virtually pain free. Personally, my personal milestone to prove that my fitting is right is to complete a century ride, but 50 miles is a good start. If you experience recurring discomfort during this process, definitely go back to your fitter and work out the details with him. Don't be afraid to ask if something doesn't seem right. The minimum you can get is an explanation of why that change will be beneficial to your fitting and goals based on your current level of fitness/conditioning. Do keep in mind that fitting is something that changes over time. It's possible that your fitter noticed that your body is currently quite flexible, in good cycling shape and based on your personal riding goals (that you most likely discussed with him: race, speed, etc.) that he set you up with an aggressive riding position/geometry. But the process to dial you in might take several visits. He should have mentioned that.
