Hex nuts or hex key bolts which are threaded on to or into the hub axle (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.
