This is so strange for me. I can't even begin to understand what most of you "polished" bicyclists are referring to a lot of the time. But I want to thank you for all the help and advice. I did understand some of what you advised and told the dealer. I don't think he thought I was a total ignoramus at that point.
I took the bicycle out for a ride today. Once I get the seat adjusted, I think I am really going to love riding my New Trek 7.6 WSD.
