Correct saddle adjustment is part of
the rules for proper riding position of the bike, along with adjusting the
position of the steering wheel and pedals. At first this new setting position may show
uncomfortable for the rider with little feet touching the pavement and trunk
fully extended but has been shown to help increase performance and prevent
injuries. The seat is adjusted relative to the vertical
and the longitudinal axis of the bicycle.Ie adjusted to the up - down (seat height) but also in the front-rear end and adjusted as to tilt. 
To adjust
the seat relative to the vertical axis we sit on the bike and turn the pedal
until the arm Crankset be perpendicular to the ground . Having already placed
the back of the foot on the pedal careful not completely vertical , ie forming
a small angle of about 30 °. There secures the seat post and have first set
ready . Placing the saddle too high will cause pain behind the knee , pain in
the crotch .
To adjust the seat to the longitudinal axis turning the pedal until it is parallel with the ground time to the front of the bike. There or who will use string ( plumb ) or that we will see with the eye . We are in this position to pass a straight knee cyclist and meets the axis of the pedal . With the help of the thread is more readily seen and thus accordingly the saddle or go forward or backward. The ride comfort is directly dependent on this setting .
For the third setting things are easier since you do not need any particular measure , but after setting the height and front back seat then climb on the bike and we are some distance sufficient to show us if they disrupt the seat or not. The initial setting is parallel to the ground while men usually raise the nose of the saddle while women download it . From this setting depends on the enjoyment of the ride because of the pressure or not the prostate.
After adjusting the seat adjustment mechanism securely to avoid unpleasant situations . Periodically check the saddle adjusting mechanism . One of the common mistakes that some people make is to move the seat forward or backward to suited their hands on the wheel .... this issue change the neck of the bike .
