As I got older, the reach to the bars was decreased, the height of the bars,
relative to the saddle got higher,

But, the height of the saddle relative to the pedals stays the same.
[heel of (low heel) shoe on pedal leg straight,
so ball of foot, on pedal, knee is slightly bent ]

the setback, saddle relative to a plumb line thru the BB
to the sitzplats on the seat, is also a useful to increase rearward,
as the position is more upright..
