).
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).
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.
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 (Appendix D or the
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
Chapter 3: Fit
NOTE:
Correct fit is an essential element of bicycling safety, performance
and comfort. Making the adjustments to your bicycle which result in correct
fit for your body and riding conditions requires experience, skill and special
tools. Always have your dealer make the adjustments on your bicycle; or, if
you have the experience, skill and tools, have your dealer check your work
before riding.
WARNING: If your bicycle does not fit properly, you may lose
control and fall. If your new bike doesn’t fit, ask your dealer to
exchange it before you ride it.
A. Standover Height
1. Diamond frame bicycles
Standover height is the basic element of bike fit (see fig. 2). It is the
distance from the ground to the top of the bicycle’s frame at that point
where your crotch is when straddling the bike. To check for correct
standover height, straddle the
bike while wearing the kind
of shoes in which you’ll be
riding, and bounce vigorously
on your heels. If your crotch
touches the frame, the bike
is too big for you. Don’t even
ride the bike around the block.
A bike which you ride only on
paved surfaces and never
take off-road should give you
a minimum standover height
clearance of two inches (5 cm).
A bike that you’ll ride on unpaved surfaces should give you a minimum of
three inches (7.5 cm) of standover height clearance. And a bike that you’ll
use off road should give you four inches (10 cm) or more of clearance.
2. Step-through frame bicycles
Standover height does not apply to bicycles with step-through frames.
Instead, the limiting dimension is determined by saddle height range.
You must be able to adjust your saddle position as described in B without
exceeding the limits set by the height of the top of the seat tube and the
”Minimum Insertion” or “Maximum Extension” mark on the seat post.
B. Saddle Position
Correct saddle adjustment is an important factor in getting the most
performance and comfort from your bicycle. If the saddle position is not
comfortable for you, see your dealer.
The saddle can be adjusted in three directions:
1. Up and down adjustment. To
check for correct saddle height
(fig. 3):
• sit on the saddle;
• place one heel on a pedal;
• rotate the crank until the pedal
with your heel on it is in the
down position and the crank
arm is parallel to the seat tube.
If your leg is not completely
straight, your saddle height
needs to be adjusted. If your
