Why you would get a professional fit and then possible undo everything by going the route that you are going?
A fit a specific
#s based thing, by changing the handlebar/handlebar reach you are changing your position on the bike.
Speak to/email the fitter and tell him what you are looking to buy and have him check the
#s . You paid good money for your fitting, they usually give you a follow visit anyway..use it my good woman
