Deep breath and chill out. : ) The first shop I stopped at wasn't so great, very busy and everyone was really rushed. The lady that helped me seemed a little confused when I told her I wanted to stick with my 105's or better and then only had one bike to show me, in the wrong size. But the next shop down the street was awesome! I spent 3 hours there, the guy took my pedals off and on at least 5 bikes, checked the air in the tires each time and took care of the seat height and things like that. He was just so great to work with that it made it lots of fun. Sadly they didn't have what I wanted, but it gave me time to come home and think about it and I still got a new pair of shorts and an excellent day out of it. : )
