Hi,
For one reason and another I have two BMC pro machines. I have been using my ibike3 on one of them with a profile i am happy with which Boyd helped me tweak.
On the second BMC it is an identical set up and riding position with the exception that it has dura ace 7900 rather than 7800, the main difference being no brake and gear cables extending out front, as they are run under the bar tape on DA7900. Would this affect my cda measurement significantly enough to warrant an entirely new profiloe or would the existing profile be close enough as not to worry about?
Any thoughts?
