The front triangle of the KM is butted.
I have a 2007 model and it has been a wonderful and versatile frame for me over the years.
On the down side, the ride is pretty stiff. Not all steel bikes have that “steel magic”. The KM (like many Surlys) seems a bit overbuilt, so in addition to it riding stiffer it is also heavy even for a steel frame.
