Ivory, those bikes are very beautiful. I like the color of the Trek bike--it looks so cheery. Let us know how your test ride goes.

I know you are interested in a road bike but since you have a mtb, I wanted to share something that I encountered with mine.

I bought a commuter bike, a Specialized Globe Vienna, last year as my doggie exerciser/noodle around the 'hood bike. I parked it by my mtb Epic and got to looking at both of the geometries. Surprisingly, the Globe's was almost identical to the Epic. I think the top tube was .5 cm less on the Globe.
