9. Spin the wheel to make sure that it is centered in the frame and clears the brake pads; then squeeze the
brake lever and make sure that the brakes are oper¬ating correctly.
SEATPOST CAM ACTION CLAMP
Some bikes are equipped with a cam action seatpost binder. The seatpost cam action binder works exactly
like the tradi-tional wheel cam action fastener (“Wheels with cam action systems”). 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 frmly clamp the seatpost (see fg. 4-1 ).
WARNING
Riding with an improperly tightened seatpost 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 seatpost.
2. Understand and apply the correct technique for clamping your seatpost.
3. Before you ride the bike, frst check that the seatpost is securely clamped.
ADJUSTING THE SEATPOST CAM ACTION MECHANISM
The action of the cam squeezes the seat collar around the seatpost to hold the seatpost securely in place.
The amount of clamping force is controlled by the tension adjusting nut. Turning the tension adjusting nut
clockwise while keeping the cam lever from rotating increases clamping force; turning it counter-clockwise
while keeping the cam lever from rotating reduces clamp¬ing force. Less than half a turn of the ten¬sion
adjusting nut can make the difference between safe and unsafe clamping force.
