WARNING: If your seat post is not inserted in the seat tube as described in B.1 ab-
ove, the seat post, binder or even frame 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 PROPAIN or a bicycle 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 E 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. PROPAIN or a bicycle 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 suciently 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 E 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 or telescopic seat post, the suspension mechanism may requi-
re periodic service or maintenance. Ask PROPAIN or your dealer for recommended service
intervals for your suspension or telescopic seat post.
Small changes in saddle position can have a substantial effect on performance and comfort.
To nd 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.
If, in spite of carefully adjusting the saddle height, tilt and fore-and-aft position, your saddle
is still uncomfortable, you may need a different saddle design. Saddles, like people, come in
many different shapes, sizes and resilience. PROPAIN or your dealer can help you select a
saddle which, when correctly adjusted for your body and riding style, will be comfortable.
WARNING: Some people have claimed that extended riding with a saddle which is
incorrectly adjusted or which does not support your pelvic area correctly can cause short-
term or long-term injury to nerves and blood vessels, or even impotence. If your saddle
causes you pain, numbness or other discomfort, listen to your body and stop riding until
you contacted PROPAIN or your dealer about saddle adjustment or a different saddle.
