A follow up - I just got back from the dealer and they've ordered another handlebar for me to try. I was reassured that if this did not do the trick they would order a smaller frame for me. I was also told that they had been in contact with Van Nicholas about this as well. I personally don't think the ordered handlebar will make much of a difference but I'm willing to try just the same.

So, my initial thoughts about expecting problems are gone.
