RIDING POSITION
Saddle Height
In order to obtain the most comfortable riding position and offer the
best possible pedaling efficiency, the seat height should be set
correctly in relation to the rider’s leg length. The correct saddle height
should not allow leg strain from over-extension, and the hips should
not rock from side to side when pedaling. While sitting on the bicycle
with one pedal at its lowest point, place the ball of your foot on that
pedal. The correct saddle height will allow the knee to be slightly
bent in this position. If the rider then places the heel of that foot on
the pedal, the leg should be almost straight.
Under no circumstances should the seat post project
from the frame beyond its “Minimum Insertion” or
“Maximum Extension” mark. If your seat post projects
from the frame beyond these markings, the seat post
or frame may break, which could cause you to lose control and
fall. After any saddle adjustment, be sure to tighten the saddle
adjusting mechanism properly before riding. A loose saddle
clamp or seat post binder can cause damage to the bicycle or
can cause you to lose control and fall. Periodically check to make
sure that the saddle adjusting mechanism is properly tightened.
Reach
To obtain maximum comfort, the rider should not overextend his or her
reach when riding.
To adjust this distance, the position of the seat can be altered in
relation to the seat pillar. (Refer to p. 65 on how to adjust the seat
clamp.)
