What size? Size for size, doesn't the the Madone have a shorter wheelbase (chainstay length) and sharper frame angles? If so, it would be more road-race whereas the Spec. would be more road-tour.
In the Trek line, the Pilot probably is closer to the Robaix. The Pilot has a normal size headtube length compared to the Robaix. Aside from that, however, but both have down-sloping top tubes, a slacker seat tube angle, a similar wheelbase, and more likely to come with a triple and 25c instead of 23c tires.
