It's important to your safety, performance and enjoyment to
understand how things work on your bicycle. We urge you
to ask your dealer how to do the things described in this
section before you attempt them yourself, and that you have
your dealer check your work before you ride the bike. If you
have even the slightest doubt as to whether you understand
something in this section of the Manual, talk to your dealer.

A. Wheels
Bicycle wheels are designed to be removable for easier
transportation and for repair of a tire puncture. In most cases,
the wheel axles are inserted into slots, called "dropouts" in
the fork and frame, but some suspension mountain bikes use
what is called a "through axle" wheel mounting system.

Wheels are secured in one of three ways:

• A hollow axle with a shaft ("skewer") running through it
which has an adjustable tension nut on one end and an
over-center cam on the other (cam action system)
• Hex nuts or hex key bolts which are threaded onto or
into the hub axle (bolton wheel)
It is very important that you understand the type of wheel
securing method on your bicycle, that you know how to
secure the wheels correctly, and that you know how to apply
the correct clamping force that safely secures the wheel.
Ask your dealer to instruct you in correct wheel removal and
installation, and ask him to give you any available manufac-
turer's Instructions.
WARNING: Riding with an improperly secured wheel can
allow the wheel to wobble or fall off the bicycle, which can
cause serious injury or death. Therefore, it is essential that
you:
1. Ask your dealer to help you make sure you know how to
install and remove your wheels safely.
2. Understand and apply the correct technique for clamping
your wheel in place.
3. Each time, before you ride the bike, check that the wheel
is securely clamped. The clamping action of a correctly
secured wheel must emboss the surfaces of the drop-
outs.
