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.
4.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.
If you have a mountain bike equipped with through
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 through
axle wheel. If you don’t know what a through axle is,
ask your dealer.
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, fig.8a & 8b).
• 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. 9)
• Hex nuts or hex key bolts which are threaded on to
or into the hub axle (bolt-on wheel, fig. 10)

The clamping action of a correctly secured wheel
must emboss the surfaces of the dropouts.
