After being measured for a new frame and comparing geometry charts,
a 54cm frame would work as well, if not better. (I really take
about a 53cm frame -- the top tube of the 56cm frame was fine for
conventional bars, but slightly long with my time trial horns.) So
if there are any 54 cm frames for sale, let me know as well.

Ice inkwell is the dark blue that was used on the 1998 Y-66.
The Y-77 was sunburst yellow that year. The Postal Blue is a
lighter blue that was used in 1999, and I think it was the color of
the Y-77, while the Y-66T was red. The decals of the '98 frames had
the model numbers, but 1999 may have omitted them. The 1999 models
had threadless headsets, whereas the 1998 models were threaded.

I can opt for a 5500 frame at no cost. The bike store has yet
to give a price to upgrade to a 5900 or Madone frame. I told the
store I was interested in a ProjectOne frame, so I may not get a
quote on a stock frame, but, if I do, I'll post it.
