My Pap Sommer is a loop frame with an IGH that comes in around 30 pounds standard. It's less if the racks and bags are off it. By putting North Road bars on it (instead of the tall bars it came with) shaved a pound or two as well.

It's a great bike for skirts and regular clothes in a way that my mixte is not. FWIW, I'm 5'3" and can get on without fuss.
