Colnago "Freuler" Geometry ???

[Louis]

It certainly has me confused. Let's say for "normal" off-the-shelf geometry I ride ST=60 c-c, TT=58.5 c-c, horizontal TT. For custom, say ST=61 c-c, same TT (i.e. longish legs, shortish torso), and I don't have a huge saddle-to-bar drop.

So, when I look at the Colnago geometry it looks funky to me, and if I just want a "basic" 60c-c bike it's not obvious what my choice would be.

Anyone care to explain what's going on, and what Freuler Geometry is intended to achieve?

TIA
