Thanks much. You are correct, soma hwy one, 44cm. They are an absolutely perfect drop design, very comfortable. I think I'll try the 46cm version just for kicks when I change the bar tape (probably after a year of riding on this tape).

They are hard to get into the old school stems though. I had to use grease and a screwdriver wedged in to keep the stem wide open while I squirmed them through the opening.
