Seat Post Cam Action Clamp - Priority Bicycle Owner's Manual

NOTE: If, on a traditional cam action system, the lever cannot be pushed all the way to a position parallel to the seat stay or chain stay,
return the lever to the OPEN position. Then turn the tension adjusting nut counterclockwise one-quarter turn and try tightening the lever
again.
WARNING: Securely clamping the wheel with a cam action retention device takes considerable force. If you can fully
close the cam lever without wrapping your fingers around the seat stay or chain stay for leverage, the lever does not leave a
clear imprint in the palm of your hand, and the serrations on the wheel fastener do not emboss the surfaces of the dropouts,
the tension is insufficient. Open the lever; turn the tension adjusting nut clockwise a quarter turn; then try again. See also the
first WARNING in this Section, p. 18.
(8) If you disengaged the brake quick-release mechanism in 3. c. (2) above, re-engage it to restore correct brake pad-to-rim
clearance.
(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 operating correctly.
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 clockwise 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 can get it will not clamp the seat
post safely.
