Tip: Angle of the saddle

We recommend using the previous saddle position you had (in terms of tilt,
height and fore aft (horizontal) position) before installing the CF Allroad Pro
Carbon seatpost.
Generally speaking a saddle should be level. This prevents the rider slipping
forwards or backwards. It also prevents too much pressure being applied either
front or rear. It is also recommended that the saddle is completely straight in line
with the frame. This allows the rider to apply equal load to the widest part of the
saddle where the sit bones are supported. If the rider finds themselves sitting too
far forward, then the fore / aft adjustment should be adjusted accordingly, or tilt
the saddle back fractionally.

For efficiency on the bike, the saddle height is the most important measurement.
Greatest power transfer occurs when the leg is almost completely straight.
Additionally the correct saddle height allows for the pelvis to be positioned in a
way which makes sitting comfortable.
Determining your saddle height can be done in one way. It uses your inside leg
measurement (without shoes) (Fig. 1). This is then used to calculate the saddle
height using a formula: Inside leg (cm) x 0.885 + 0.5 cm = Saddle height (cm)
(measured from the bottom bracket axle to the saddle middle) (Fig. 2). This
method does not however account for crank length variance.
