B) Seat Post Cam Action Clamp; C) Brakes - Kona bicycle Owner's Manual

B. Seat Post Cam Action Clamp
Some bikes are equipped with a cam action seat post
binder. The seat post cam action binder works exactly like
the traditional wheel cam action fastener (Section 4.A.2)
While a cam action binder looks like a long bolt with a
lever on one end and a nut on the other, the binder uses
an over-center cam action to firmly clamp the seat post
(see fig. 8a).
WARNING: Riding with an improperly tightened
seat post can allow the saddle to turn or move and
cause you to lose control and fall. Therefore:
1. Ask your dealer to help you make sure you know
how to correctly clamp your seat post.
2. Understand and apply the correct technique for
clamping your seat post.
3. Before you ride the bike, first check that the seat
post is securely clamped.
Adjusting the seat post cam action mechanism
The action of the cam squeezes the seat collar around
the seat post to hold the seat post securely in place. The
amount of clamping force is controlled by the tension
adjusting nut. Turning the tension adjusting nut clock-
wise while keeping the cam lever from rotating increases
clamping force; turning it counterclockwise while keeping
the cam lever from rotating reduces clamping force. Less
than half a turn of the tension adjusting nut can make the
difference between safe and unsafe clamping force.
WARNING: The full force of the cam action is
needed to clamp the seat post securely. Holding the
nut with one hand and turning the lever like a wing nut
with the other hand until everything is as tight as you
20
can get it will not clamp the seat post safely.
WARNING: If you can fully close the cam lever
without wrapping your fingers around the seat post or
a frame tube for leverage, and the lever does not leave
a clear imprint in the palm of your hand, the tension is
insufficient. Open the lever; turn the tension adjusting
nut clockwise a quarter turn; then try again.

C) BRAKES

WARNING: 1. Riding with improperly adjusted
brakes, worn brake pads, or wheels on which the rim
wear mark is visible is dangerous and can result in
serious injury or death.
2. Applying brakes too hard or too suddenly can lock
up a wheel, which could cause you to lose control and
fall. Sudden or excessive application of the front brake
may pitch the rider over the handlebars, which may
result in serious injury or death.
3. Some bicycle brakes, such as disc brakes (fig. 11)
and linear-pull brakes (fig. 12), are extremely power-
ful. Take extra care in becoming familiar with these
brakes and exercise particular care when using them.
4. Some bicycle brakes are equipped with a brake force
modulator, a small, cylindrical device through which
the brake control cable runs and which is designed to
provide a more progressive application of braking force.
A modulator makes the initial brake lever force more
gentle, progressively increasing
force until full force is achieved. If
your bike is equipped with a brake
force modulator, take extra care in
becoming familiar with its perfor-
mance characteristics.
5. Disc brakes can get extremely
hot with extended use. Be careful
not to touch a disc brake until it
has had plenty of time to cool.
