My first reaction was if you could have shorten the front brake cable. But a second look reveals that the stem bolt was kind of "in the way" of the cable path. If not binding then full steam ahead! I guess the cantilever stop was designed with non-aero brake cabling in mind. I can't get over how clean your bike is. Great job!

Edit: What type of camera did you use for the shots? They look like they could go into a catalog.
