GENERAL RIDING INFORMATION 3

your body backwards in order to trans-
fer weight to the back, simultaneously
decreasing the rear braking force and
increasing the front braking force. It is
especially important when you are de-
scending. The weight transfer is more
evident on bikes equipped with a front
suspension fork as it dips under braking
and thus intensifies the weight transfer.
To control your speed effectively and
bring your bike to a halt safely you need
to be in control of the wheel lockup and
the weight transfer. You should practice
braking and weight transfer techniques
in safe places free from traffic and
distractions.
CAUTION:
It is crucial to apply correct
tightening force on fasteners, nuts,
bolts, screws on your bicycle so as to
avoid components’ failure or damage,
which can result in your losing control
of the bike and falling. Using too little
force may result in the fastener not
holding securely, moving and under-
going fatigue. Applying too much force
may cause the fastener to strip threads,
stretch, deform or break. If you observe
any problems at the pre-ride check,
consult a professional bicycle mechanic
instantly for advice. Before every ride
You should always make a pre-ride
check. It should include the following
points: Clean the frame and fork and
examine them CAREFULLY for any
signs of cracks, corrosion, dents, paint
peeling or other defects. If anything
suspicious is found, contact your local
bike dealer for a proper inspection.
These are important safety checks and
very important to help prevent acci-
dents, injury and shortened product
lifespan. Do not ride the bicycle if you
see any defects in the frame and fork.
Check if the brakes are working proper-
ly by testing their efficiency in a parking
lot or on a side road. When the brake
is applied with full force, the distance
from the brake lever to the handlebar
should be bigger than 2 cm. Check the
brake pads too - you should replace
damaged and worn out elements and
adjust immediately when improper func-
tion is noticed. To do this, contact your
dealer or the closest authorised bike
service. Remember that improper setup
of the brake can cause serious injury or
death. Follow the brake manufacturer’s
instructions closely for setup and main-
tenance. The instructions are supplied
in the box with every bicycle. If you are
in doubt about their correct function,
contact your local bicycle shop.
Control position adjustments
It is possible to adjust the angle and
position of brakes and shift controls on
the handlebars. Ask your dealer or bike
shop to make the necessary adjust-
ments for you. If you choose to adjust
the control lever angle on your own, be
sure to re-tighten the clamp fasteners
to the recommended torque (see the
manufacturer’s instruction manual).
Brake reach
In many bikes brake levers can be
adjusted for reach. If your hands are
small or if squeezing the brake levers
is difficult for you, ask your dealer to
adjust the reach or have shorter reach
brake levers fitted.
WARNING:
With shorter brake lever
reach, correct adjustment of brakes be-
comes more critical, full braking power
should be applied within available brake
lever travel. Brake lever travel inade-
quate for full braking power application
can result in loss of control, which may
cause serious injury or death.
Check the brake cables and their hous-
ing for kinks, rust, broken strands, or
frayed ends. If you notice any damage,
you should ask a bicycle shop to re-
place the cables immediately. Damaged
cables can seriously impede braking ef-
ficiency. If your bicycle has rim brakes,
inspect the rim walls to check if they are
not excessively worn out by the brakes.
A groove made by manufacturer on
the sidewall of a rim should always be
visible. On rims without a groove/safety
mark it is important to check if the brak-
ing surface has not become deformed
by the brake pads. The rims should be
replaced as soon as a visible deforma-
tion of the rim surface occurs.
For your information:
in some
jurisdictions there are requirements
to determine the minimum leg-length
dimension (clearance between the
rider’s crotch and the top tube of the
bike when stood in front of the saddle)
in the manual. This does not apply to
all bicycles, yet the so called stand
over height constitutes a basic element
of bike fit and plays an important role,
especially when dismounting the bike
quickly. While determining the correct
stand over height you should strad-
dle your bike while wearing the kind
of shoes which you are going to wear
while riding, and bounce energetically
on your heels. Your crotch touching
the frame means that the bike is too
big for you. You should not ride the a
bike. The minimum stand over height
clearance for the bike ridden on paved
surfaces only and never taken off-road
should be 5 cm (approx. 2 inches). The
minimum stand over height clearance
for the bike to be ridden on unpaved
surfaces should be 7.5 cm (approx. 3
inches). The minimum stand over height
clearance for the bike to be used off
road should be 10 cm (four inches) or
more. Stand over height does not apply
to bicycles with step-through frames. In
such bicycles the range of the saddle
height determines the limiting dimen-
sion. Make sure you are able to adjust
the position of your saddle as shown
in this manual herein above without
exceeding the limits set by the height of
the top of the seat tube and the mini-
mum insertion or maximum extension
mark on the seat post. Remember that
toe-clearance may vary according to
any modifications introduced to tires or
cranks.
Steering system.
The steering system includes: handle
bar, stem, headset and fork. All ele-
ments should be connected firmly for
riding safety.
WARNING:
Proper assembly and func-
tioning of the steering system is critical
for your safety!!!
