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.
5).
!
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 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 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.
WARNING: If you can fully close the quick release 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.
C. Brakes
WARNING:
!
1. Riding with improperly adjusted brakes or worn brake pads is dangerous and can result in serious
injury or death.
2. Applying brakes too hard or too suddenly can lock up a wheel, which could cause you to lose
control and fall. Sudden or excessive application of the front brake may pitch the rider over the
handlebars, which may result in serious injury or death.
3. Some bicycle brakes, such as disc brakes (fig. 11) are extremely powerful. Take extra care in
becoming familiar with these brakes and exercise particular care when using them.
