Yes, it is a Quick disc 4. And yes they moved the seat back to make a better fit. Unfortunately, the carbon fork/stem made it not compatable to raise the handle bars. Candy and I did make it to PA to ride the GAP trail, well, 41 miles of it. Blame it on Jim Kenney - he's the one that introduced me to the trail. Great fun and experience.@Philpug is between M and L in most Cannondales he's tried. You should be able to do some tweeking to fit well.
What did you get? Quick?
They make a Quick Neo as well.
