As far as the Bianchi is concerned, no, because I am realizing that the frame is likely a tad too small for me. So even with drop bars, it's not going to feel right. I suppose a x-long stem might work. I hadn't thought about it.

Though the Giant Rapid 2 could easily be converted to a drop bar bike it lacks enough clearance for bigger tires. I need to have studded tires on this bike for winter. They came in quite handy yesterday morning when there looked like a thin layer of ice on all the roads.

How feasible is it to build a CX from the frame up? Anyone done this before?
