Bike fit? (2)

What is the thought of getting a bike fit 1 month before ironman? I feel pretty comfortable. someone told me few changes may make the difference too be really comfortable and get more power. My concern is making changes 1 month before the race. The changes would not be drastic.

Thanks

Who would be doing the fitting? There is nothing wrong with making changes, but it depends on why you are making them, and who is going to make those changes.
