Now that I have the S-A X-FDD hub finally built up and mounted up front the bike is a little more balanced front/rear against the massive SRAM 7-speed out back.
The front wheel touches down now with the bike unladen, but with the lock in the back rack the front wheel still wants to lift off the ground. If the ground is even a little bit unlevel the wheel flops all the way to the lower side . Now, without the headset-mounted cable-stop for the front cantilevers, there isn't anything to stop the front end from turning nearly all the way around except for pulling on the cable housings for the rear brake and rear hub something terrible.
