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 on
previous page.
2. Front and back adjustment. The saddle can be adjusted
forward or back to help you get the optimal position on the
bike. 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 front and back adjustment, make
sure that the clamp mechanism is clamping on the straight part
of the saddle rails and is not touching the curved part of the
rails, and that you are using the recommended torque on the
clamping fastener(s) (Appendix F.3 or the manufacturer's
instructions).
3. Saddle angle adjustment. Most people prefer a horizontal
saddle; but some riders like the saddle nose angled up or down
just a little. Your dealer can adjust saddle angle or teach you
how to do it. If you choose to make your own saddle angle
adjustment and you have a single bolt saddle clamp on your
seat post, it is critical that you loosen the clamp bolt sufficiently
to allow any serrations on the mechanism to disengage before
changing the saddle's angle, and then that the serrations fully
re-engage before you tighten the clamp bolt to the
recommended torque (Appendix F.3 or the manufacturer's
instructions).

WARNING!
When making saddle angle adjustments with a single bolt
saddle clamp, always check to make sure that the serrations on
the mating surfaces of the clamp are not worn. Worn serrations
on the clamp can allow the saddle to move, causing you to lose
control and fall.
Always tighten fasteners to the correct torque. Bolts that are
too tight can stretch and deform. Bolts that are too loose can
move and fatigue. Either mistake can lead to a sudden failure of
the bolt, causing you to lose control and fall.
Note: If your bicycle is equipped with a suspension seat post, the
suspension mechanism may require periodic service or
maintenance. Contact a bicycle specialist for intervals for your
suspension seat post.
Small changes in saddle position can have a substantial effect on
performance and comfort. To find your best saddle position, make
only one adjustment at a time.
WARNING!
After any saddle adjustment, be sure that the saddle adjusting
mechanism is properly seated and tightened before riding.
A loose saddle clamp or seat post clamp can cause damage to
the seat post, or can cause you to lose control and fall. A
correctly tightened saddle adjusting mechanism will allow no
saddle movement in any direction. Periodically check to make
sure that the saddle adjusting mechanism is properly tightened.
