Seatpost Quick Release - Giant MULTI-SPEED Manual

(3) Using the correct size wrench, tighten the axle nuts enough so that the wheel
stays in place; then use a wrench on each nut simultaneously to tighten the nuts
as tight as you can.
(4) Push the rear derailleur back into position.
(5) Re-engage the brake quick-release mechanism to restore correct brake pad-
to-rim clearance; 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. Seatpost Quick Release
Some bikes are equipped with a quick-release seat post binder. The seatpost
quick-release binder works exactly like the wheel quick-release (Section 4.A.1)
While a quick release looks like a long bolt with a lever on one end and a nut on
the other, the quick release uses a cam action to firmly clamp the seat post (see
fig. 6).
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 quick
release.
3. Before you ride the bike, first check that the seatpost is securely clamped.
Adjusting the seatpost quick release mechanism
The action of the quick release cam squeezes the seat collar around the seat post
to hold the seat post securely in place. The amount of clamping force is con-
trolled 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 seatpost
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 seatpost safely.
