Geometry strikes me a bit odd - long chainstays and not much fork rake?
That's because, strictly speaking, it is not a PX10 but a PX10E. Here's a photo of an E model and a plain model from the same approximate time period:
The forward of the two bikes is the E model; the difference in geo is quite clear. BTW, the back bike has what appear to be stock clinchers, so it is likely (technically) a UX10.
