doubt, consult an experienced bike mechanic. Rear hub axle bolts should be tightened
alternately! Do not over-tighten the bolt on one side without counter tightening on the
other!
If your bicycle has been equipped with through axle front or back wheels, make sure that
you have been provided with the manufacturer’s instruction manual, which you are to
follow when installing or removing wheels with this system. If you are not sure what
a thru-axle/through axle is, ask your dealer for information. It is crucial for you to
understand what type of a wheel securing method is required on your bicycle, to
know how to secure the wheels correctly, and how to apply the correct clamping
force to secure the wheel safely. Ask your dealer to instruct you on how to remove and
install the wheel on your bicycle properly, and provide you with any available manufac-
turer’s instruction manual.
Brakes
There are three general types of bicycle brakes: rim brakes, which work by squeezing
the wheel rim between two brake pads; disc brakes, which work by squeezing a hub-
mounted disc between two brake pads; and internal hub brakes. All three can be oper-
ated by way of a handlebar mounted lever. On some models of bicycle, the internal hub
brake is operated by pedalling backwards. This is called a Coaster Brake.
WARNING: Riding with brakes that have not been adjusted properly, worn brake
pads, or wheels with a visible rim wear marks constitutes a hazard and can cause
serious injury or death. Too hard or too sudden application of the brakes can cause
the wheel to lock up and make you lose control and fall. Applying the front brake
too suddenly or excessively may result in the rider’s pitching over the handlebars,
potentially causing serious injury or death. Bicycle brakes may be very power-
ful, especially disc brakes or linear-pull brakes. You should be extra careful while
learning how to operate such brakes and take particular care while using them.
WARNING: Disc brakes can heat up extremely when their application is pro-
longed. Don’t touch a disc brake until it has had plenty of time to cool. Remem-
ber that brake pads in all brake types will wear out, which will ultimately reduce
their eciency.
For information on how to operate and maintain your brakes and when to replace the
brake pads see the brake manufacturer’s operation and maintenance manual. If you
have not been provided with the manufacturer’s instruction manual, contact your dealer
or the brake manufacturer. When replacing worn or damaged parts the manufacturer-
approved genuine spare parts are to be used only.
WARNING: It’s vital for your safety to learn and remember which brake is con-
trolled by which brake lever on your bicycle.
