Hi,
I haven't seen anyone else mention this, but when I set my saddle back,
like way back on the Nitto lugged seat post, I have to measure my saddle
height from BB to where my sit bones go, not parallel to the seat post
tube, thus lowering the saddle more in relation to the ground.
Also, I have to adjust my saddle further if I make changes in shoe &
pedal thicknesses.
The (PBH x 0.883 = saddle height) & (PBH - 10-11cm = saddle height)
equations have always worked for me as a good place to start. My wife has a
73cm PBH and starting with these formulas as a place to work from has
worked out for her too.
