a Presta valve tube using a Presta headed
bicycle pump, remove the valve cap; unscrew
(anti-clockwise) the valve stem lock nut; and
push down on the valve stem to free it up.
Then push the pump head on to the valve
head and inflate. To inflate a Presta valve with
a Schraeder pump fitting, you’ll need a Presta
adapter (available at your local bike shop)
which screws on to the valve stem once you’ve
freed up the valve. The adapter fits into the
Schrader pump fitting. Close the valve after
inflation. To let air out of a Presta valve, open
the valve stem lock nut and depress the valve
stem.
Warning: Patching a tube is
an emergency repair. If you do
not apply the patch correctly
or apply several patches,
the tube can fail, resulting in
possible tube failure, which
could cause you to lose control
and fall. Replace a patched
tube as soon as possible.
4.F.3. Clincher and tubular tyres
There are primarily two kinds of bicycle tyres:
The clincher tyre and the tubular tyre.
Clincher tyres are shaped like a “U” in cross
section, with wire or Kevlar beads on the outer
edge of both sides that hook onto the rim and
hold the tire in place on the wheel over the
inner tube. Tubular tyres do not have beads –
the outer edges of the tyre are sewn together
around the inner tube, which is then glued to
the rim to hold it in place.
Your Nukeproof bicycle will be equipped with
clincher tyres from the factory, however riders
may wish to purchase a second set of wheels
utilising tubular tyres for our gravel models. If
you install wheels with tubular tyres on your
bicycle, it is very important that you obtain and
read all safety information about tubulars from
the wheel and tyre manufacturers, in particular
the information on the proper technique for
gluing the tyres to the rim. Improperly glued
tubular tyres can separate from the rim
causing a serious crash. It is up to the rider to
take responsibility for ensuring their tubular
wheels and tyres are safe to use.
Warning: Improperly installed
tubular tyres can separate
from the rims during a ride,
possibly causing a serious
crash that may result in injury
or death.

Your Nukeproof bicycle is equipped with
precision components which require precise
adjustment and care to function properly.
Whenever components are changed or
adjusted on the bicycle, it is critical for safety
and performance reasons that all fasteners be
tightened in accordance with the listed values
below. It is recommended that you permit
your Authorised Nukeproof Dealer to perform
the following adjustments, as they have the
proper tools and experience to ensure it is
done correctly. Improper adjustments can
result in safety hazards – ensure you read all
applicable documentation and have the correct
tools prior to attempting any adjustments
yourself.
Note that prior to assembling and tightening
any bolts, all threads must be generously
greased with a quality, non-lithium type grease.
Torque wrenches with scale appropriate for the
torque setting are strongly recommended for
tightening all threaded fasteners.
Nukeproof strongly recommends the use of
carbon assembly compound/friction paste for
all areas of clamping to carbon fibre, such as
the seatpost to frame, the stem to fork, and the
handlebar to stem joints. Benefits to using this
paste include reduced corrosion potential, and
a decrease in required clamping force needed
to support a given load. The paste should be
evenly spread on the carbon surface under the
clamped area.
Warning: Under-tightening or over-
tightening fasteners can result in
damage to the bicycle that can lead
to possible failure, which could cause
you to lose control and fall, resulting
in injury or death.

The fork length also detailed as axle to crown
(A-C) cannot be exceeded. If you wish to
change your fork, please consult with your
Authorised Nukeproof Dealer that the bikes
maximum A-C is not exceeded. Using a fork
that exceeds the A-C may lead to frame failure,
injury, or death.

If you wish to change your shock for
an upgrade or a different model to your
preference, please consult with your
suspension supplier and Authorised Nukeproof
Dealer to ensure the shock is the correct size,
fitting and the tune suits the kinematics of your
Nukeproof bicycle.

The majority of Nukeproof Bike’s unique
frame numbers are found on the underside of
the bottom bracket shell. The unique frame
number for a Megawatt is found inside the
frame and behind the motor housing. To
view the frame number at the back of the
motor housing the air from the rear shock
needs released allowing the rear triangle
to rise and give visibility. Your Authorised
Nukeproof Dealer and Nukeproof Bikes do
not have an obligation to keep a record of this
number. Please take a note of the number
for insurances and theft prevention/recovery
purposes.

Do not exceed the fork and frame maximum
tyre widths. Check with your Authorised
Nukeproof Dealer the maximum tyre width
that can be installed to your specific bike.
Please note some manufacturer tyre and
rim combinations can be wider when fitted
together, always check for clearance when
tyres are changed to a different model. Tyre
rub can damage frame and will not be covered
by warranty if incorrect tyre size has been
used. Tyres rubbing on frame and forks can
cause instability when riding, leading to loss of
control, injury, and death.
