Contrary to common belief, it is not possible to 
determine  the  correct  seat  angle  through  the 
proportion of underleg - upperleg. First of all it 
is almost impossible to measure this proportion 
exactly  and,  secondly,  the  saddle  height  and 
the position of the cyclist on the saddle have an 
effect on the correct seat angle.
In accordance with theory the point where the 
power of the upper leg goes into the under leg 
has  to  be  above  the  centre  of  the  pedal  axle 
when crank and pedal are horizontal. It not only 
gives a correct fl uency of power but also has an 
effect on the position on the saddle. If the power 
transmission of the movement locomotion and 
the pedal mechanism of the bicycle are not in 
one line then the result will be a very unrestful 
position  on  the  saddle,  which  can  lead  to  lost 
effi ciency.
