WARNING! Remember that for each of the following steps you must read attentively,

and abide strictly by the Manual and/or instructions provided by the manufacturer of the

component in question, which are given to you at the time of purchase of your bicycle and/

or are available on its manufacturer’s website. If the manual of the component was not

provided, you can request them from your AUTHORIZED RIDLEY DEALER and/or consult

their manufacturers’ websites which feature such manuals, before using your new bicycle.

What we provide below is merely a number of recommendations based on our many years

of experience in competitive cycling, but in no way do they constitute an implicit or explicit

assumption on our part of any liability for components that we have not manufactured.

1. BRAKES. First of all, and above all, check the brake system for effectiveness by

operating the brake lever several times in a row. Braking effectiveness should

remain the same even after intensive braking. If this is not the case, you must bring

back your bicycle immediately to your AUTHORIZED RIDLEY DEALER. In any case, be

careful when applying the front brake too hard. If you suddenly apply the front brake

with excessive force, the rear wheel may fly upward and the front wheel can skid to

one side, with the consequent loss of control and a likely fall.

2. RAPID PEDAL RELEASE. Also make sure that the rapid pedal release mechanisms of

your bicycle are well adjusted. The shoes you wear should fit well, and they should

easily engage the pedals. By rapidly pushing and pulling, make sure that your feet

in no way disengage from the pedals. They must be removed from the pedals only

when you want them to be, and this should occur easily without the need to apply

any special effort, by a typical swift sideways motion. Should you have difficulties

removing them, bring back your bicycle to your AUTHORIZED RIDLEY DEALER

before using the bicycle again.

3. GEAR CHANGE MECHANISMS. Make yourself familiar with the gear change

mechanisms that are installed on your bicycle. Make sure that the power shift is

enabled, and avoid using combinations of ratios that make the chain work at a large

angle with respect to the ideal plane drawn through the bike’s center from front to

back. In such case there is a risk that a sudden and improper gear change may cause

the chain to get stuck between the sprockets, causing the bicycle to stall suddenly

and, as a consequence, the cyclist to fall. Such events, even if they do not cause a fall,

can result in gear change maladjustment. More specifically, the exact position of the

rear derailleur can change when it shifts the chain to the innermost sprocket that

is the closest one to the wheel spokes. In such case either because the derailleur is

bent, or because it becomes loose from its support on the frame, or because the end

of stroke becomes misadjusted, or under the combined effect of all these factors, it

may happen that the lower end of the derailleur gets inserted between the spokes,

causing structural damage and a sudden fall, which is inevitable and dangerous.

Make sure that the handlebar remains secure on the stem, has not moved from its

position, and does not move if you apply torsion, bending, or rotary forces.

4. STEERING. Make sure that the steering does not have any play when you push it

vigorously back and forth while holding the bike firmly with the front brake fully

applied. Take back the bike to your AUTHORIZED RIDLEY DEALER if any abnormal

movements or noises appear after this test; otherwise raise the speed gradually

and make sure your bike rides straight and steady, without wobbling, oscillations,

or vibrations. Such events are rare; they can be caused by various factors, acting

individually or in combination. If you experience vibrations that appear starting from

a certain speed and become pronounced when you release the handlebar, take your

bicycle to your AUTHORIZED RIDLEY DEALER for inspection of components and/or

for bicycle repair.

4. BASIC FACTS YOU MUST KNOW BEFORE USING YOUR BICYCLE FOR THE FIRST

TIME

The bicycle has been so far the most efficient vehicle invented by humankind. However, the

bicycle, being a two-wheeled vehicle, must be kept in balance by the cyclist. In addition, by

its nature it cannot provide any protective envelope, thus leaving the cyclist fully exposed

and particularly vulnerable to surrounding hazards. This is why it is necessary to be most

attentive while riding a bicycle. It should be also noted that the energy of movement,

which depends on the mass and speed, is always much higher than what we intuitively

imagine. In the case of an impact, your kinetic energy does not disappear, but rather turns

into structural deformation and heat. In the case of a head-on collision, it is evident that

nobody is expecting structural integrity either for the bicycle or for the cyclist. However,

it is understood that even when hitting surmountable obstacles such as bumps in the

pavement, potholes, manhole covers surrounded by raised asphalt, grates with slits in

which the wheel can get caught, etc., an impact may occur that can be destructive.

The problem of which we must be aware is that speed changes determined by the impact

are by their nature almost instantaneous, so the forces generated in a fraction of a

second within which the speed change occurs can become enormous. An example: If an

average cyclist who weighs 80 kg with his bicycle rides at the speed of 40 km per hour and

hits an unexpected obstacle with the front wheel, reducing his speed to 10 km per hour

in an instant, the bicycle and the cyclist are exposed to a force that depends, in addition

to the momentum, on the time within which the above change took place. In the case in

question, if the change occurs in 1/10th of a second, the force acting on the bicycle-cyclist

system is about 600 kg, but if the change took place in 1/100th of a second, the force could

reach 6,000 kg! Therefore, in the event that your bicycle sustains damage as a result of an

unfortunate impact, and you fall as a consequence of breakage or deformation of any part

of the bicycle, it is not the bicycle to blame, but rather the obstacles that have caused the

impact. This is the reason why it is always necessary to exercise maximum caution while

riding bicycles, slowing down substantially where the road may be increasingly bumpy or

in any case of poor visibility.

The materials RIDLEY uses for making the frames and forks are either metal alloys or

composites based on carbon fiber. Examples of the first type are steels and various

aluminum and titanium alloys. Both metals and composites are of the highest quality and

offer mechanical characteristics that assure maximum safety to the user. It is important

to note that the two above-mentioned classes of materials behave differently in the event

of an unfortunate destructive impact. Metal alloys can snap, but they first experience

twisting and bending, whereas the composites just fracture, even though they are more

impact-resistant than metal alloys. Of course they are not highly brittle, but they have

a typical behavior, and if they fracture, it means that the force that destroyed them and

that would also deform or break to pieces an equivalent structure made of a metal alloy

exceeding the maximum strength, however high it may be for a product that was well

designed and made in accordance with industry standards.
