Warning: Technological advances
have made bicycles and bicycle
components more complex, and the
pace of innovation is increasing.
It is impossible for this manual to
provide all the information required
to properly repair and/or maintain
your bicycle. To help minimize the
chances of an accident and possible
injury, it is critical that you have any
repair or maintenance which is not
specically described in this manual
performed by your dealer. Equally
important is that your individual
maintenance requirements will be
determined by everything from your
riding style to geographic location.
Consult your Authorised Nukeproof
Dealer for help in determining your
maintenance requirements.
Warning: Many bicycle service
and repair tasks require special
knowledge and tools. Do not begin
any adjustments or service on your
bicycle until you have learned from
your Authorised Nukeproof Dealer
how to properly complete them.
Improper adjustment or service may
result in damage to the bicycle or in
an accident which can cause serious
injury or death.
If you want to learn to do major service and
repair work on your bike:
• Ask your Authorised Nukeproof Dealer
for copies of the manufacturer’s
installation and service instructions
for the components on your bike or
contact the component manufacturer.
thoroughly and lightly oil the chain. Wipe
off excess oil. Lubrication is a function of
climate. Talk to your Authorised Nukeproof
Dealer about the best lubricants and the
recommended lubrication frequency for your
area.
5.A.4. After every long or hard ride or after
every 10 to 20 hours of riding
Squeeze the front brake and rock the bike
forward and back. Does everything feel
solid? If you feel a clunk with each forward or
backward movement of the bike, you probably
have a loose headset. Have your Authorised
Nukeproof Dealer check it.
Lift the front wheel off the ground and swing it
from side to side. Does it feel smooth? If you
feel any binding or roughness in the steering,
you may have a tight headset. Have your
Authorised Nukeproof Dealer check it.
Inspect both rims for damage. Check the
spoke-holes on the rim for any cracks that
may have formed due to fatigue If cracks
are found do not ride it – take the wheel
to your Authorised Nukeproof Dealer for
replacement. Also inspect the brake surface
for wear (relative to other surfaces). If a
noticeable amount of wear has occurred, do
not ride it – take the wheel to your Authorised
Nukeproof Dealer for inspection and possible
replacement. Ignoring these signs of wheel
wear or damage can lead to failures of the rim.
Grab one pedal and rock it toward and away
from the centre line of the bike; then do the
same with the other pedal. Anything feel
loose? If so, have your Authorised Nukeproof
Dealer check it.
Look at the brake pads. If they are starting to
look worn or not hitting the wheel rim squarely
then have your Authorised Nukeproof Dealer
adjust or replace them.
Carefully check the control cables and cable
housings for signs of rust, kinks, and fraying.
If you notice as of these signs, have your
Authorised Nukeproof Dealer replace them.
Squeeze each adjoining pair of spokes on
either side of each wheel between your thumb
and index nger. Do they all feel about the
same? If any feel loose, have your Authorised
Nukeproof Dealer checks the wheel for tension
and trueness.
Check to make sure that all parts and
accessories are still secure and tighten any
which are not.
• Check the frame, particularly in
the area around all tube joints; the
handlebars; the stem; and the seatpost
for any deep scratches, cracks, or
discolouration. These are signs of
stress-caused fatigue and indicate that
a part is at the end of its useful life and
needs to be replaced.
Warning: Like any mechanical
device, a bicycle and its components
are subject to wear and stress.
Different materials and mechanisms
wear or fatigue from stress at
different rates and have different life
cycles. If a component’s life cycle
is exceeded, the component can
suddenly and catastrophically fail,
causing serious injury or death to the
rider.
Scratches, cracks, fraying, and discolouration
are signs of stress caused fatigue and indicate
that a part is at the end of its useful life and
needs to be replaced. While the materials and
workmanship of your bicycle or of individual
components may be covered by a warranty for
a specied period of time by the manufacturer,
this is no guarantee that the product will last
the term of the warranty. Product life is often
related to the kind of riding you do and to the
treatment to which you submit the bicycle.
The bicycle’s warranty is not meant to suggest
that the bicycle cannot be broken or will
last forever. It only means that the bicycle is
covered subject to the terms of the warranty.
5.A.5. As required
If either brake lever fails the Mechanical Safety
Check (Section 1.C. - Mechanical Safety),
don’t ride the bike. Have your Authorised
Nukeproof Dealer check the brake. If the chain
won’t shift smoothly and quietly from gear to
gear, the derailleur is out of adjustment. See
your Authorised Nukeproof Dealer.
SECTION 5 - service
• Ask your Authorised Nukeproof Dealer
to recommend a book on bicycle
repair.
• Ask your Authorised Nukeproof Dealer
about the availability of bicycle repair
courses in your area.
We recommend that you ask your Authorised
Nukeproof Dealer to check the quality of your
work the rst time you work on something and
before you ride the bike, just to make sure that
you did everything correctly. Since that will
require the time of a mechanic, there may be a
modest charge for this service.
5. A. SERVICE INTERVALS
Some service and maintenance can and
should be performed by the owner and require
no special tools or knowledge beyond what is
presented in this manual.
The following are examples of the type of
service you should perform yourself. All other
service, maintenance and repair should be
performed in a properly equipped facility
by a qualied bicycle mechanic using the
correct tools and procedures specied by the
manufacturer.
5.A.1. Break-in Period
Your bike will last longer and work better if
you break it in before riding it hard. Control
cables and wheel spokes may stretch or “seat”
when a new bike is rst used and may require
readjustment by your Authorised Nukeproof
Dealer. Section 1.C. - Mechanical Safety
will help you identify some things that need
readjustment.
5.A.2. Before every ride
Check Section 1.C. - Mechanical Safety
5.A.3. After every long or hard ride
If the bike has been exposed to water or grit;
or at least every 100 miles: Clean the bike
