Operation Manual

18
If you have a mountain or road 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.
If you do not have a bicycle with a through-axle wheel mounting system, it will
have wheels 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, g.8 a & b)
• A hollow axle with a shaft (“skewer”) running through it which has a nut on
one end and a tting for a hex key, lock lever or other tightening device on the
other (through bolt, g. 9)
• Hex nuts or hex key bolts which are
threaded on to or into the hub axle (bolt-on wheel, g. 10)
Your bicycle may be equipped with a different securing method for the front
wheel than for the rear wheel. Discuss the wheel securing method for your
bicycle with your dealer.
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 manufacturer’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 dropouts.
1. Front Wheel Secondary Retention Devices
Most bicycles have front forks which utilize a secondary wheel retention
device to reduce the risk of the wheel disengaging from the fork if the wheel is
incorrectly secured. Secondary retention devices are not a substitute for correctly
securing your front wheel.
Secondary retention devices fall into two basic categories:
a. The clip-on type is a part which the manufacturer adds to the front wheel
hub or front fork.
b. The integral type is molded, cast or machined into the outer faces of the
front fork dropouts. Ask your dealer to explain the particular secondary retention
device on your bike.
WARNING: Do not remove or disable the secondary retention device.
