CAUTION: Please read this manual carefully. It contains
important safety information.
WARNING: Extreme bicycle ride is a dangerous sport and
requires an amazing amount of skills. By engaging in
that type of activity user accepts the risk of injury or even
death. Even the best bicycle will not help to drop perfect-
ly if the user does not have suicient skills. Also, the best
protection equipment does not guarantee a hundred
percent safety. Please note that in this kind of riding,
a user can only trust his abilities and must accept the
inherent risk. While riding a user can reach signicant
speeds and therefore face signicant hazards and risks.
Inspect a bicycle and equipment carefully and be sure
that it is in perfect condition before each ride. If possible
consult with bike-park personnel, expert riders, and race
oicials on conditions and equipment advisable. Always
wear appropriate safety gear, including an approved full-
face helmet, full nger gloves, body armor, bright and
visible clothing that is not so loose, that it can be tangled
in the bicycle or objects at the side of the road or trail,
shoes that will stay on your feet and will grip the pedals
(make sure that shoe laces cannot get into moving parts,
and never ride barefoot or in sandals). Always use pro-
tective eyewear to protect against dirt, dust, and bugs.
WARNING: Some of the service procedures require
specialist tools and good mechanical skills. Therefore,
to minimize the risk of serious or even fatal accidents,
maintenance and assembly work on your bike should be
carried out by an authorized bicycle workshop.
WARNING: Failure to maintain, check and properly adjust
the suspension system may cause suspension malfunc-
tion, in a result of which a user may lose control and fall.
WARNING: Introducing changes in the suspension ad-
justment can alter the handling and braking character-
istics of your bicycle. It is forbidden to change the sus-
pension adjustment unless a user is thoroughly familiar
with the suspension system manufacturer’s instructions
and recommendations. Users should always check for
changes in the handling and braking characteristics of
the bicycle aer the suspension has been adjusted by
taking a careful test ride in a safe area.
WARNING: As with all mechanical components, the
frame is subjected to wear and high stresses. Dierent
materials and components may react to wear or stress
fatigue in dierent ways. If the design life of a compo-
nent has been exceeded, it may suddenly fail possibly
causing injuries to the rider. Any form of crack, scratches,
or change of color in highly stressed areas indicates that
the life of the component has been reached and it should
be replaced.
IMPORTANT NOTICE: This manual is not intended as
a comprehensive use, service, repair, or maintenance
manual. Please consult your dealer for advice and your
dealer may also be able to refer you to classes, clinics,
or books on bicycle use, service, repair, or maintenance.

TABLE OF CONTENTS
Riding a bicycle can be dangerous. Keep this in mind and be cautious at all times. See and be seen. Use lights
and reective clothing in low light conditions. Wearing a helmet when riding can protect the head and save
a life. Always conduct a pre-ride check (detailed information can be found further in this manual).
Never ride the bicycle if you observe any technical problems or have any doubts about the proper functioning of
any elements in the bicycle. Keep the bike clean and well maintained. It is strongly recommended to carry a pump,
spare inner tube, patch kit, and a basic tool kit. It could be required in case of a at tire or other common mechani-
cal problem. If any doubts or questions ask a bicycle dealer for advice on that issue. If the bicycle is equipped with
gears and user can choose a gear combination that is the most comfortable for riding conditions. Gears will allow
a rider to maintain a constant rate of pedalling. Use lower gears for going uphill and higher gears for going down-
hill. Ease up on your pedalling pressure when you shi gears. Ask a bicycle dealer to give more advice on that issue
if needed.
Pay attention to the brakes - they can be powerful and if activated too aggressively, may cause a crash. You should
spend some time to get a better feel of the brakes on a side road or empty parking lot before the rst ride. Avoid
riding too fast, especially downhill. It is easy to lose control of the bicycle and crash at high speeds, and also you
will nd it very diicult to slow down especially if the hill is steep.
If a bike has been equipped with suspension, the increased speed a rider may develop will also increase the risk
of injury. For example, the front of the bike may dive on the suspension fork while hard braking. A Rider can eas-
ily lose control and fall if he is not prepared for this. Please, learn how to operate your suspension system safely.
Thanks to the suspension the wheels can follow the terrain better, which improves control and comfort.
This improved capacity may provide an opportunity for riding faster, but riders should be careful, not to mis-
take the enhanced capabilities of the bicycle for their riding skills. Improving skills takes time and practice.
It is highly recommended to use locks to protect a bicycle from the. Even if you are planning to be away from
a bicycle for just a few minutes never leave your bike unlocked while unattended.

is an all-new carbon enduro frame, dedicated to the diicult terrain and riding conditions.
With perfect lateral stiness, it is a great 29-er enduro machine with aggressive geometry and 160mm of pro-
gressive frame travel. Thunderbird CF will work great with the modern heavy-duty forks with 160-170mm trav-
el. Despite the big wheels, the new Thunderbird CF has the Dartmoor DNA and it will not let you down on big
jumps, drops, or even in bike parks. For keeping the frame trouble-free, all pivot points are working on the sti
axles mounted on the sealed Max-type bearings.
The progressive suspension design of the Thunderbird CF is perfect for both types of shocks: spring shocks
and large volume air shocks. The construction reduces also the negative impact of braking on the suspension
operation. The front triangle and seat stays are made of high-quality carbon ber with increased wall thickness
for better stiness. The massive rocker is made of one piece of forged aluminum. To ensure the proper strength
and durability the whole chainstay and the inserts in the points that are the most exposed to overload in carbon
material are made of aluminum as well.
Before we decided to launch the Thunderbird CF frame for mass production, it not only passed a series of tests
on a load machine, where the overloads were much greater than required by the standards but it was also
strictly tested on the toughest trails of many European enduro races by our team rider Marcin Motyka - a legend
of the Polish bicycle scene. Another testing period included uncompromised shredding in the Austrian, Czech
and Polish bike parks, where our R&D Jan Kiliński was checking the strength of the frame on the high drops and
long jumps.

It says it all. With this aluminum beast, you are ready to huck whatever you want on the track.
170mm of travel in the back and up to 190mm in the front ensure enough room for errors and party laps. Simple
Horst link design built around proven four-bar suspension is balanced for pedal eiciency and braking to shred
factor. It is not a do-it-all marketing scheme bike. We like our bikes to be as progressive and sti as possible,
ready to jump over roots rather than be glued to them. 29-inch wheels with 148x12mm Boost hubs are already
an overkill to ride over rough terrain. Our Enduro Team rider uses Thunderbird Superenduro both for
Downhill and EWS races during a season. Not a UCI fan? Want to be really bad? Put a double crown on it and
ride like it’s 2010’s freeride golden age again!

ENDURO
Enduro bikes were created for long mountain trips in diicult terrain, riding in the mountains, oen unpaved
routes. These bikes are more versatile and also allow a rider to ride uphill, although it is not the most pleasant.
The travel of shock absorption is smaller than that of downhill bikes. The most common are full-suspension bikes
with 160mm of travel, but there are also hardtails. They have a fairly short sti frame, an adjustable seat post, and
hydraulic brakes with large discs. Sometimes there is a front derailleur. Some models even allow you to quickly
change the geometry of the frame, i.e. adapt the bike to the climb or descent. Weight approx. 12-16 kg.
In enduro, the ability to eiciently overcome not only winding paths, trails full of unevenness, sharp descents,
and demanding climbs will be useful. It is up to the rider which route he will take because he has full freedom in
this matter. There are no inaccessible places for enduro bikes, and the more diverse the better. You can go crazy
and bounce a bit o the ground. It is not the results or the quick time that counts, only having fun. This is the
essence of a real enduro. A bicycle should be free, reliable, and its user should be able to use its full potential. In
enduro, a rider chooses his path.
Freeride bikes are downhill bikes tailored to the needs of ordinary people. Minimum stroke of the shock absorb-
er 170 mm, solid frame, wide handlebars. All this is within the limits that can be mastered by intermediate riders.
When driving fast, wide tires and sensitive hydraulic brakes are essential. The high position of the handlebars in
relation to the saddle and the position of the rider shied backward ensure comfort when riding downhill. It is
also possible to overcome at sections. The weight of around 18 kg makes the climb very diicult, which is why
freeriders use the lis most oen. It is denitely a bike for fans of extreme experiences.

sion on a full-suspension bike.
Watch the video
INITIAL SAG
Suspension settings are a matter of personal prefer-
ence. Some riders prefer a so setup, others a hard
setup. Depending on the riding style, skills, and con-
ditions on the route. The suspension on a trail/ en-
duro bike works ne with approximately 20% -30%
initial sag. For the front shock, the value of 20-25%
should be assumed, while for the rear shock the ini-
tial deection should be about 25-30% of the total
stroke. Before starting work, set the return damping
to the fully open position.
To measure the SAG, follow the instructions/indica-
tions below:
•
Move the O-ring on the stanchion so it touches the
fork seal, the same for the rear shock.
•
Stand on the pedals with your full body weight
with full equipment: protective armor, helmet,
neck protector, water bottle or water bag, etc. It is
importantthattheequipmentandclothingreect
the real riding conditions to give the most accurate
results. While standing on the bike, bend the sus-
pension several times, then push the O-ring against
the shock seals again. It is best to have someone
to help, but you can deal with it yourself, for ex-
ample by leaning against the wall of the building.
•
GetothebikecarefullyandmeasuretheSAGwith
a ruler or tape measure printed on the stanchion,
or ask someone to read the value on the scale
when standing on the bike in a neutral position
(slightlybentkneesandhandsinelbows).Inate
ordeatethedamperuntilthedesireddeection
of the shock is achieved.
In the case of an ungraduated rear shock, to determine
the percentage of initial deection, its total deection
must rst be measured, because it is shorter than those
given in the catalog for the total travel of the rear swing-
arm. To do this, reduce the pressure in the air chamber
so that you can bend the shock to its extreme posi-
tion, then inate it and measure the distance between
the O-ring and the seal. For example, a bicycle with
160 mm travel has a rear shock with 70.87mm deection,
assuming a SAG of 30%, its value measured on the shock
absorber piston with correctly set pressure should be
21.26mm (70.87 x 0.3 = 21.26mm).
REBOUND
In the damper return damping setting, the so-called
„curb test” works best. To proceed with the adjustment,
follow the instructions/indications below:
•
Unscrew the Rebound valve to the extreme position, de-
pending on the manufacturer on the casing towards the
„bunny” symbol, „Fast” or minus sign. There is no return
damping in this position.
•
Find a less traveled road in your area with a medium
size curb.
•
While sitting in the saddle, without using the brakes,
slowly descend from the saddle. The damper piston re-
tractsrst,thenreturnstoitsoriginalpositionandbe-
gins to oscillate until it stops.
•
To counteract the “rocking” phenomenon, turn Re-
bound two clicks towards the “turtle” symbol (+; “slow”)
andrepeatthetestbyrollingothecurb.Byadjusting
in this way, you should observe the moment when the
damperstopsoscillatingaerarebound.
•
The resulting setting is the initial setting from which you
shouldstart.Furtheradjustmentsfortwoclicksback-
ward or forwards can be made on the trail depending
on riding conditions and preferences.
•
Rememberthat,aswiththeSAG,thereturnsuppression
is determined by the weight of the user and all equip-
ment. The greater the weight of the bike user, the great-
er the damping will be needed to absorb the rebound
energy.
It is best to set the front shock return damping as follows:
•
Start by unscrewing the damper to the extreme position
as it was in the case of the damper. Stand next to the
bicycle, depress the shock as far as possible, and release
it vigorously. Observe that the front wheel is clear of the
ground. Increase the damping by two clicks by using the
adjusteronthebottomoftherightshockleg,turning
towards the „turtle” symbol („+”; „slow”).
•
Repeatthisprocessuntilthewheelstopsspringingo
the ground. The basic setting obtained in this way can
be corrected on the trail depending on the driving con-
ditions and individual preferences.
•
Finally, get on the bike and on a straight road, vigorously
bending the suspension, check that the front and rear
work evenly. By pressing the suspension in this way,

TABLE OF CONTENTS
Most air shocks have a compression speed damp-
ing adjustment implemented by a single knob. It en-
ables smooth or gradual regulation until the shock
is blocked. This adjustment is most oen used while
driving, adapting the shock to the type of route.
The fully open position is most oen used when de-
scending on uneven terrain when we want the best
traction. Slowing down the compression speed to
about half of the range is used in normal riding on
at sections and in the case of riding on ow routes
so that the suspension does not absorb the user’s
speed while riding on moguls. This setting is the
most used and the most universal, also for people
who like to jump on a bike. The shock absorbs en-
ergy when hitting a punch, so some riders prefer to
increase compression damping.
The extreme setting is the least used, most oen when
climbing steep climbs.
More advanced designs of the shock, mount a damper
with two regulators, fast and slow compression. Slow
compression damping acts on the rst half of the shock
travel, mainly when braking, negotiating steep descents,
rides, or moguls. Increasing it improves the eiciency of
pedaling, prevents „swinging” and reduces the collapse
of the suspension when overcoming the above-men-
tioned elements. Similar to the case when you have only
one compression knob. Therefore, the adjustment is
made in the same way.
High-speed compression damping aects the second
half of the stroke of the shock from the middle of the de-
ection to the moment of compression.
15
Typically, less experienced riders do not use this adjust-
ment and it remains in the open position. Users who
like to ride more aggressively, forcing the suspension to
work quickly, aer hitting a large obstacle will feel that
the suspension dives too quickly to the end of the stroke,
they can counteract this phenomenon by increasing the
damping of quick compression.

Correct tightening of the bicycle fasteners, nuts, and bolts are essential. Too little force and the fastener may
not hold securely. Too much force and the fastener may tear, stretch, distort or break the thread. Either way,
incorrect torque can damage the component, which can cause you to lose control and fall. In case of doubt or
problems found during your test ride, seek immediate advice from a professional bicycle mechanic.
See the instructions of the suppliers of the suspension fork, rear shock, and other parts that come with this
frame. Do not use the bicycle until all problems have been resolved. Riding a bicycle with any defects may be
dangerous to health and life. If you are not a qualied bicycle mechanic, do not make any of these adjustments
yourself and seek advice from your local bicycle dealer.
The rear suspension bolts (rear shock and pivots) have been tightened at the factory to the specied torque.
If you re-adjust, take particular care when re-tightening. DO NOT lubricate any of the pivot points. The factory

It is recommended that the user take care of the
frame of his bike, which will allow him to enjoy it for
a longer period. Before each ride, the bicycle should
always be inspected, which should include the fol-
lowing points:
•
clean the frame - remember that high-pressure
washing may damage some parts of the bike, so
avoid it,
•
carefully inspect for signs of potential failure in-
cluding cracks, corrosion, dents, paint peeling, and
any other signs of potential problems and misuse.
