3.2 Saddle position
Correct saddle adjustment is important in
getting the best performance and comfort
from your bicycle.
a Up and down adjustment.
Your leg length determines the correct
saddle height. To check for correct saddle
height:
• sit on the saddle
• place one heel on a pedal
• rotate the crank until the pedal with your
heel on it is in the lowest position and the
crank is parallel to the seat tube.
• your leg should be almost straight. If not,
your saddle height needs adjusting.
To adjust the saddle height, loosen the seat
post fixing bolt (see fig. 10) and move the seat
post up or down as required. Then, make sure
that the saddle is parallel to the top tube of
the bike, and retighten the seat post fixing
bolt tight enough so that you cannot twist the
saddle out of alignment. Check the
adjustment as described above. The seat post
must NOT project from the frame beyond its
Minimum Insertion mark (see fig. 11).
NOTE:
In order to guarantee the quality of the frame,
Giant uses different types of seat posts for
gents and ladies bikes Lafree Twist. The
difference between the 2 types of seat posts
are the positions of the Minimum Insertion
marks.
The minimum insertion length of the seat post
for the ladies bike is 15 cm.
The minimum insertion length of the seat post
for the gents bike is 10 cm.
Keep this in mind when you need a new seat
post. Be careful when you switch seat posts
of ladies and gents bikes.
b Front and back adjustment.
To find the most comfortable position,
loosen the saddle clamp and adjust the
saddle forward or back to suit you.
Retighten the saddle clamp. (See fig. 12).
c Saddle tilt adjustment.
Most people prefer a horizontal saddle,
but some riders prefer to have the saddle
tilted up or down a little. Adjust the saddle
tilt by loosening the saddle clamp, tilting
the saddle to the desired position, and re-
tightening the saddle clamp.
Very small changes in saddle position will
make a big difference. Make only one
change at a time, and only in small steps
until you have found your most
comfortable position.
WARNING:
After any saddle adjustment, be sure to
tighten the saddle adjusting mechanism
properly before riding. Periodically check to
make sure that the saddle adjusting
mechanism is properly tightened.
