Rodar, that makes sense. But you could still have a longer wheel base w/ the same ST angle by increasing the seat stay length. Hope this isn't a dumb question but what is KOPS?

"So bikes made for powerful riding -- road racing, TT, track -- have steeper ST angles, while bikes made for more relaxed riding -- touring, randonneuring, "comfort" -- have slacker ST angles."

Isn't bike touring in a way powerful riding? I need all the help I can get and I definitely have more power being more forward on the cranks and my comfort isn't compromised. There is more leverage working against your thighs the further back a person is relative to the cranks.

I have a custom co-motion road bike and when I was considering the Americano, the bike shop was going to recommend that Co-motion not make major changes in regards to angles. Their thinking was since I could do a 12 hour day in the saddle on my road bike w/ no pain why make changes just because it's a touring bike? (Talking about bar and saddle placement in relation to the BB, not wheelbase etc...)

I am not convinced that a touring bike needs to have a slacker angle to provide all day comfort. That is more dependent on TT length and HT angle which determines bar placement.
