Fit; Standover Height; Saddle Position - Derby cycle IMPULSE 2.0 SPEED Owner's Manual

WARNING: Failure to confirm compatibility, properly
install, operate and maintain any component or
accessory can result in serious injury or death.
WARNING: Exposed springs on the saddle of any
bicycle fitted with a child seat can cause serious
injury to the child. Cover all springs of the saddle
and the seatpost to avoid that the child can get hurt.
WARNING: Changing the components on your bike
with other than genuine replacement parts may
compromise the safety of your bicycle and may void
the warranty. Check with your dealer before changing the
components on your bike.

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
). 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
vertical.
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.
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).
