Tip: Seatpost extension
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. A) . 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. B) . This
method does not however account for crank length variance.
