Thanks for the helpful advice. I'm glad that many people support the idea of a fit. I've read other message boards where the consensus a mixed.

Crankin - I was thinking of waiting because I figured I'd save the fit for when I would do the most riding. That way, I can get used to the new setup and how it feels and have a whole season ahead of me of riding. I feel like if I get fit towards the end, I'll only ride for a couple of months and then will have to put the bike away for the winter (or ride on rollers which isn't as much fun). Also need to see if I can save some money in case I need to buy new parts.
