Regarding this, alu frame are not uncomfortable as people make it out to be, a good set-up and reasonable tyres pressure can make it pretty comfortable, even my old Dolan soak up the road well for a heavy alu track frame.
My geared bike is an aluminium ribble audax and although I've toured on it, it's really not that comfortable. I've had a fit from the bike whisperer, so it's not the set up, and my tyres aren't (always) ridiculous pressure. I can't see the PX alu frame being miles better than the ribble, for the price.
It's still a significantly harsher ride than steel (and I presume carbon, although I've never personally ridden a carbon bike).
