Thank you guys, I have to agree with you!! I'm learning about proper fit and I will really take this into consideration. I just came back from a 18 mile ride with my "new-to-me" Centurion Elite RS and it rides like a dream, it was a good choice, this bike is a 58cm (23") frame, I still have to put the seat up considerably to have the proper leg angle. Therefore, if I get a second bike, I will stay on the 58 - 60cm frame. THANKS again.
