PART 1
3.B - Saddle Position
Section 3. Fit
GT Bicycle Owner’s Manual
If your leg is not completely straight, your
saddle height needs to be adjusted. If your
hips must rock for the heel to reach the
pedal, the saddle is too high. If your leg is
bent at the knee with your heel on the pedal,
the saddle is too low.
Figure 3. Saddle Position
Ask your dealer to set the saddle for your
optimal riding position and to show you how to
make this adjustment. If you choose to make
your own saddle height adjustment:
• loosen the seat post clamp
• raise or lower the seat post in the seat tube
• make sure the saddle is straight fore and aft
• re-tighten the seat post clamp to the
recommended torque (See manufacturer’s
instructions).
Once the saddle is at the correct height, make
sure that the seat post does not project from the
frame beyond its “Minimum Insertion” or
“Maximum Extension” mark (fig. 4).
NOTE: Some bicycles have a sight hole in the
seat tube, the purpose of which is to make it easy
to see whether the seat post is inserted in the
seat tube far enough to be safe. If your bicycle
has such a sight hole, use it instead of the
“Minimum Insertion” or “Maximum Extension”
mark to make sure the seat post is inserted in
the seat tube far enough to be visible through
the sight hole.
If your bike has an interrupted seat tube, as is
the case on some suspension bikes, you must
also make sure that the seat post is far enough
into the frame so that you can touch it through
the bottom of the interrupted seat tube with the
tip of your finger without inserting your finger
beyond its first knuckle. Also see NOTE above
and fig. 5).
WARNING
If your seat post is not inserted in the seat
tube as described in B.1 above, the seat post
may break, which could cause you to lose
control and fall.
