Scott’s frame is built using one of my favorite tubesets. It’s the Columbus Spirit. It’s light, offers good stiffness and it looks really cool. The downtube is a bi-oval that has what I guess could be described as facets. The toptube is oval and has facets too. I like to sub in an externally butted seattube and the chainstays are round/square/round with a taper. The seatstays are round at the top and morph into and Aero shape mid way down and then back to round with a taper. All in all the tubeset is very extreme and a great example of how technically advanced steel tubes really are.
