Yet I am sure people do it and they are just fine.
So, is this slow, mm, fit adjustment thing a myth? Do I have anything to fear in making bigger adjustments if a current fit isn't working out, or riding my race bike in the morning and then getting on the upright bike in the afternoon?
I ride several different bicycles, yet my fit on all those bicycles is the same or very close to it.
I also ride a lot, and the adjustments can come down to millimetres.
However, if your bicycle is obviously set up very badly for you ... for example, if your saddle is way too low or way too high ... you will want to make a larger adjustment. If certain fit elements are significanly out, it's more important to get things into a ball park range as soon as possible. It's when you get down to the almost right stage where you'll find tune in mms.
