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.

Wheels

Bicycle wheels are designed to be remov-
able for easier transportation and for repair
of a tire puncture. In most cases, the wheel
axles are inserted into slots, called "drop-
outs" in the fork and frame, but some sus-
pension mountain bikes use what is called
a "thru axle" wheel mounting system.
If you have a mountain bike equipped
with thru axle front or rear wheels, make
sure that your dealer has given you the

manufacturer's instructions, and follow
those when installing or removing a thru
axle wheel. If you don't know what a thru
axle is, ask your dealer.
Wheels are secured in one of three ways:
1. 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, fig.
4-1 & fig. 4-2 )
2. A hollow axle with a shaft ("skewer")
running through it which has a nut on one
end and a fitting for a hex key, lock lever
or other tightening device on the other.
(through-bolt, fig. 4-3 )
3. Hex nuts or hex key bolts which are
threaded on to or into the hub axle. (bolt-on
wheel, fig. 4-4 )
Your bicycle may be equipped with a dif-
ferent securing method for the front wheel
than for the rear wheel. Discuss the wheel
