I would think a Nitto technomic would be stiffer than using an adapter + threadless stem. There simply is just less parts to deal with in the equation. With that - how is a threadless setup simpler than a quill stem? They certainly aren't as easy to adjust.

On the bike being a sherman tank - from what I understand about the Schwinn Peloton, I imagine it to be light years away from Schwinn's actual sherman tanks. *cough Varsitys cough*

I have a nitto technomic (the 110) sitting at home waiting for me to un-box it. If its half of what I expect it to be it will be amazing.
