Nice America! Have you ever tried it with front bags i/o rear? Those Fujis have fairly low-trail geometry, and some folks find they handle better with more loading in the front.
Great observation. It has close to 0 trail based on my measurements. I have not yet taken the plunge for a front loading bad / rack system. Interestingly, there is only one mount for what appears to be fenders. However, given the tight clearances, perhaps the mounts were for a front rack system, since fenders were not really in vogue in the early 80's when this model was released.
At the time I purchased the rear rack, I was not as informed on trail and geometry, and real bike racks were kind of the norm (a decade ago). But I love this bike for what it does, which is that it is a great commuter bike. Only thing I might change is currently, running a 42x18, which, for what I am doing with it, a little bit too much gear when going up hill.
