WARNING
: The shorter the brake lever reach, the more critical it is to have
correctly adjusted brakes so that full braking power can be applied within available
brake lever travel. If the brake lever travel isn’t enough to apply full braking power it
can result in loss of control, which may result in serious injury or death.
It’s important to your safety, performance and enjoyment to understand how things
work on your bike. We urge you to ask your stockist how to do the things described
in this section before you attempt them yourself, and that you ask your stockist to
check your work before you ride. If you have even the slightest doubt as to whether
you understand something in this section, talk to your stockist. See also Appendix
A, B, C and D.
A. Wheels
Bicycle wheels are designed to be removable for easier transportation and for puncture
repairs. 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 wheels make sure your
stockist has given you the relevant instructions, and follow those when installing or
removing a through axle wheel. If you don’t know what a through axle is, ask your
stockist.
Frog Bikes wheels are secured in one of two ways:
• Frog 52 upwards use a hollow axle with a shaft (“skewer”) running through it
which has an adjustable tension nut on one end and an over-centre cam on
the other
Tadpole, Frog 43 and Frog 48 have 15 hex nuts or hex key bolts which are threaded
onto or into the hub axle
Your bike may be equipped with a different securing method for the front wheel than
for the rear wheel. Discuss the wheel securing method for your bike with your stockist.
It is very important that you understand the type of wheel securing method on your
bike, 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 stockist to
instruct you in correct wheel removal and installation, and ask him to give you the
relevant instructions.
WARNING
: Riding with an improperly secured wheel can allow the wheel to
wobble or fall off the bike, which can cause serious injury or death. Therefore, it
is essential that you:
• Ask your stockist to help you make sure you know how to install and remove
your wheels safely.
• Understand and apply the correct technique for clamping your wheel in place.
• Each time, before you ride,check 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 bikes 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 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 stockist to explain the particular secondary retention device on your bike.
WARNING
: Do not remove or disable the secondary retention device. As its
name implies, it serves as a back-up for a critical adjustment. If the wheel is not
secured correctly, the secondary retention device can reduce the risk of the wheel
disengaging from the fork. Removing or disabling the secondary retention device
may also void the warranty. Secondary retention devices are not a substitute for
correctly securing your wheel. Failure to properly secure the wheel can cause the
wheel to wobble or disengage, which could cause you to lose control and fall,
resulting in serious injury or death.
