When I bought my Della Santa in (about 1992) it included a fit. It was really good and I was riding pretty fast on that set up. Especially up hill. That was when I was 40 years old. But fits don’t last forever. When I got a new bike at 60 I tried to set it up based on that fit. My knees were killing me and I was not happy. But I had learned enough over the years so that I could adjust it and I am happy now. Well, I can’t climb like those days but now at 69 I can get around.
