I am 69 and have ridden a level saddle for a long time. I have not changed that, but I have had a need to lower the seat posts and shorten or change degrees, or both, to all my bikes. I am shorter than I used to be, and not as flexible. I am talking about relatively small changes. I have done that twice in the past 4 or 5 years. This spring, the fit seems to still fit. Last year was a change year. No rant here. If it keeps me comfortable, I am good with it.
