(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.
4.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.
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.
