mark on the seat post. If the seat post is at the min/max mark and the seat post
is not visible through the sight hole (frames equipped with a sight hole), the seat
post is not inserted deeply enough into the seat tube and should be lowered
until it can be seen through the sight hole. Do NOT cut the seat post short!
If your seat post is at the min/max mark and/or the seat post is not visible
through the sight hole (frames equipped with a sight hole) and the saddle is not
high enough, the seat post must be replaced with a longer seat post.
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
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.
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 D 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 D 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. Ask your
dealer for recommended service intervals for your suspension seat post.
