Some more pics while I'm stuck at work.
Frameset. Note the Mavic headset and mystery BB. Note that this is neither the post I'm using nor my saddle height, and the stem will change also.
Brake-bridge detail. Love this.
Mystery BB close up.
Mr. Davidson is a talented fellow. The lugs are the nicest most thought-out of any bike I've owned, by far -- the two head tube lugs meet and join behind the head tube (need to get a pic of this.) He also seems to have gone back to plug the vent holes on the frame.
