HOW THE COMPONENTS WORK
the outside, between the shovel and fork axle nut. If your bike has a secondary retention device, connect it.
(2) While pushing the wheel firmly to the top of the slots in the fork dropouts, centre the wheel rim in the
fork, use a 15 mm wrench or an adjustable six-inch wrench to tighten the axle nuts as much as possible.
(3) Close the brake pads, and then turn the wheel to make sure it is centred in the frame and does not
obstruct the brake pads.
c) How to remove a rear wheel secured with screws
(1) Open the brake pads.
(2) Move the rear derailleur to the highest gear (the smallest rear sprocket) and pull the derailleur back
with your right hand.
(3)Loosen the axle nuts with a 15 mm wrench or an adjustable six-inch wrench.
(4) Lift the rear wheel a few inches of soil and, with the derailleur still pulled back, push the wheel for-
ward and down until it exit the rear dropouts.
d) How to install a rear wheel secured with screws
(1) Move the rear derailleur into its outside and pull the derailleur back with your right hand.
(2) Place the chain on the smallest sprocket. Then, insert the wheel between the tips of the frame and
pull it up to the tips. The washers of the axle nuts must be on the outside, between the frame and axle
nut.
(3) Tighten the axle nuts as much as possible, using an adjustable wrench or a 15 mm six-inch wrench.
(4) Push the rear derailleur back until it gets into position.
(5) Close the brake, spin the wheel to make sure it is centred in the frame and does not obstruct the
brake pads.
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. 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-centre cam action to firmly
clamp the seat post.
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
counter clockwise 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.
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 will not
clamp the seat post safely.
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 insuffi-
cient. Open the lever; turn the tension adjusting nut clockwise a quarter turn; then try again.
