No one mentions head tube angle: those are in the 66/69 degree now. A 135mm stem will stabilize and slow down a very nervous 71 degree head angle. Then you have a 58cm bars to go along. It´s close to cyclo cross/ road geometry. A 66 degree front will work only w/ a much shorter stem and wide bars. And you are dealing w/ a longer front center, result from the shallow head tube.
It´s the whole package.
