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 suicient 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 significant
speeds and therefore face significant 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
oicials on conditions and equipment advisable. Always
wear appropriate safety gear, including an approved full-
face helmet, full finger 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 aer 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. Dierent
materials and components may react to wear or stress
fatigue in dierent 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.
1. INTRODUCTION – IMPORTANT INFORMATION AND WARNINGS

4
TABLE OF CONTENT
Riding a bicycle can be dangerous. Keep this in mind
and be cautious at all times. See and be seen. Use lights
and reflective clothing in low light conditions. Wearing
a helmet when riding can protect thhead 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 prob-
lems 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 flat tire or other common
mechanical problem. If any doubts or questions ask a bi-
cycle 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 rid-
ing conditions. Gears will allow a rider to maintain a con-
stant rate of pedaling. Use lower gears for going uphill
and higher gears for going downhill. Ease up on your
pedaling 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 first 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 find it very diicult to slow down especially
if the hill is steep.
If a bike has been equipped with suspension, the in-
creased 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
easily 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 mistake
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 bicy-
cle from the. Even if you are planning to be away from
a bicycle for just a few minutes never leave your bike un-
locked while unattended.

signed pivot position allows for high pedaling eiciency.
The design uses an extended shock mount to keep the
seat tube intact to accommodate any type of dropper
post. The low position of the bottom bracket ensures
high stability on rough terrain, and the flat head tube an-
gle (Blackbird 65˚, Bluebird 66˚) ensures excellent ride
control no matter how steep the trail. The rear axle is
a 148 x 12 mm bolt in Boost standard.
3. BLACKBIRD AND BLUEBIRD
A reliable and functional solution(system) could be
simple. Based on an opinion that comes from rid-
er’s feedback, Dartmoor enhances the ideas and
provides new solutions which make every minute
on trails full of fun and happiness. A bicycle is a sim-
ple machine with massive potential. That is why
designing Blackbird frame 160mm of travel, mod-
ern geometry and tough but lightweight construc-
tion, Dartmoor chose simplicity and functionality.
Without any doubt, Enduro is a sport that requires
maximum versatility from a bicycle.Long climbs,
descents in the most diicult conditions, jumps,
and drops - these are the standard challenges that
the equipment has to face. For those who seek trail
bicycle which is durable as Enduro, the Dartmoor
team has made Bluebird frame 130 mm of travel.
Based on its own and other riders’ experience, Dart-
moor has placed a rigid, single-pivot structure at
the heart of the bike. That simple solution allows us
to create a modern product that will meet the ex-
pectations of even the most demanding riders.The
advanced swingarm cage, consisting of 12 welded
parts and tubes, is very sti, and the carefully de-

TABLE OF CONTENT
The Dartmoor frames are based on a well-designed single
pivot suspension that uses the damper extension yoke for
superior performance.
On the one hand, when the user is struggling with diicult
climbs using low gear, he can enjoy high pedaling eicien-
cy with anti-squad properties of around 100%.On the oth-
er hand, when it hits the toughest descents at high gear,
it uses 160mm of full travel, the suspension design gives
a pedal kickback of less than 2%. This results in less fa-
tigue during descents, because the legs do not have to
absorb the energy of so many hits.
The suspension kinematics of our frames are linear, the
configuration is completely up to the user and his prefer-
ences, depending on how the user tunes the rear shock
using the tokens. From a more progressive with a limited
air chamber for those who like bigger jumps, to a more lin-
ear curve using a full stroke for those who prefer demand-
ing trails rather than hitting huge drops. Nevertheless,
the suspension is only „half the battle”. Equipped with
a rigid 17mm axis of rotation, the linkage of the swingarm
to the front triangle, it spins on three Max bearings (with
increased ball count) with LLU full contact seals filled
with high-quality Mobil synthetic grease, providing bet-
ter protection against dust and water. Fewer pivot points
in the designed suspension structure give less chance of
catching a play in the bearings. Therefore, when buying
a Dartmoor frame, the future owner receives the perfect
equipment to overcome the most demanding routes.

TRAIL
Trail bikes allow riders comfortable uphills on long
mountain trails, combining the features of enduro
and cross country. They are available in full-sus-
pension or hardtail versions. Shock absorption at
a level between 130 mm - 150 mm, will allow a rider
to easily deal with unevenness and obstacles, such
as steep climbs. They allow for more aggressive
driving than cross country but are less dynamic.
Compared to the enduro, they are a bit lighter and
allow for a more pleasant ride uphill. The maneu-
verability of these bikes is influenced by the wide
handlebars, adjustable seat post, and the weight-
ing of the front wheel during the descent. Wheels
are usually 29 inches, although trail bikes with
a combination of 29 „front and 27.5” rear wheels
(the so-called Mullet) are also popular, as well as
with both 27.5 „wheels. The use of wide tires makes
it easier to overcome obstacles in the field. Based
on the emerging bike parks, a group of trail bike
enthusiasts has emerged. If someone would like to
go on a long trip on singletrack and not the most
diicult mountain paths for pleasure, he should
opt for a comfortable trail bike rather than enduro.
ENDURO
Enduro bikes were created for long mountain trips in
diicult terrain, riding in the mountains, oen unpaved
routes. These bikes are more versatile and also allow
a rider to ride uphill, although it is not the most pleas-
ant. 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 eiciently 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, relia-
ble, and its user should be able to use its full potential. In
enduro, a rider chooses his path.

FREERIDE
Freeride bikes are downhill bikes tailored to the needs of
ordinary people. Minimum stroke of the shock absorber
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
shied backward ensure comfort when riding downhill.
It is also possible to overcome flat sections. The weight
of around 18 kg makes the climb very diicult, which
is why freeriders use the lis most oen. It is definitely
a bike for fans of extreme experiences.
DOWNHILL
Downhill bikes are bikes designed for descents(down-
hills) at high speed, in diicult and steep terrain. The
rider reaches speeds of up to 80 km / h on a rocky and
bumpy route. It also happens that these bikes bounce
into the air by avoiding obstacles. Such overload forces
the use of bicycles with a compact and sti structure.
The sturdy frame has a low center of gravity, and the
wide handlebars with a short stem increase the maneu-
verability of the bike. Strong and resistant tires are re-
quired, full suspension with long travel, usually 180 mm
to 220 mm, and hydraulic brakes with large 203 mm
discs. DH bicycles weigh approximately 15-20 kg. Their
construction practically excludes going uphill, because
the damper absorbs almost all the energy put into pedal-
ing. Even navigating on flat terrain can be diicult, which
is why the ski slopes are usually located near the lis.

Currently, the most commonly used hub size standard
is Boost (technology) - 148x12 mm for the rear hub, and
110x15 mm for the front hub. It is a relatively new solu-
tion in which the wider track increases the stiness of
the wheel, maneuverability, and dynamics of the bicycle.
Other, slightly older standards for hub sizes are 142x12
mm and 135x10mm for the rear hub, as well as 100x15
mm, 110x20 mm, and 100x9 mm for the front hub.

Tutorial video showing how to set up the suspension on
a full-suspension bike. Watch the video
INITIAL SAG
Suspension settings are a matter of personal preference.
Some riders prefer a so setup, others a hard setup. De-
pending on the riding style, skills, and conditions on the
route. The suspension on a trail/ enduro bike works fine
with approximately 20% -30% initial sag. For the front
shock, the value of 20-25% should be assumed, while for
the rear shock the initial deflection 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/indications 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, wa-
ter bottle or water bag, etc. It is important that the equip-
ment and clothing reflect the real riding conditions to give
the most accurate results. While standing on the bike, bend
the suspension 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 example by leaning
against the wall of the building.
• Get o the bike carefully and measure the SAG with a ruler
or tape measure printed on the stanchion, or ask some-
one to read the value on the scale when standing on the
bike in a neutral position (slightly bent knees and hands
in elbows). Inflate or deflate the damper until the desired
deflection of the shock is achieved.
In the case of an ungraduated rear shock, to determine the
percentage of initial deflection, its total deflection must first
YT
6. SUSPENNSION SETTINGS
be measured, because it is shorter than those given in
the catalog for the total travel of the rear swingarm. To
do this, reduce the pressure in the air chamber so that
you can bend the shock to its extreme position, then in-
flate it and measure the distance between the O-ring and
the seal. For example, a bicycle with 160mm travel has
a rear shock with 70.87mm deflection, 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 – return damping
(rebound speed)
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-
tracts first, then returns to its original position and be-
gins to oscillate until it stops.
• To counteract the “rocking” phenomenon, turn Re-
bound two clicks towards the “turtle” symbol (+; “slow”)
and repeat the test by rolling o the curb. By adjusting
in this way, you should observe the moment when the
damper stops oscillating aer a rebound.

15
TABLE OF CONTENT
• The resulting setting is the initial setting from
which you should start. Further adjustments for
two clicks backward or forwards can be made on
the trail depending on riding conditions and pref-
erences.
• Remember that, as with the SAG, the return sup-
pression is determined by the weight of the user
and all equipment. The greater the weight of the
bike user, the greater 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 adjuster on the
bottom of the right shock leg, turning towards the
„turtle” symbol („+”; „slow”).
• Repeat this process until the wheel stops springing
o the ground. The basic setting obtained in this
way can be corrected on the trail depending on the
driving conditions and individual preferences.
• Finally, get on the bike and on a straight road, vig-
orously bending the suspension, check that the
front and rear work evenly. By pressing the suspen-
sion in this way, bend it in the range of 80-90%, if it
is diicult, it may turn out that the shock or damp-
er needs to be adjusted in terms of the air chamber
capacity. To do this, contact an experienced service
provider who will adjust the size of the chamber
with the help of tokens.
COMPRESSION – speed of compression
(deflection)
Most air shocks have a compression speed damping
adjustment implemented by a single knob. It enables
smooth or gradual regulation until the shock is blocked.
This adjustment is most oen used while driving, adapt-
ing the shock to the type of route. The fully open posi-
tion is most oen used when descending 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 flat sections and in the case of rid-
ing on flow routes so that the suspension does not ab-
sorb the user’s speed while riding on moguls. This set-
ting is the most used and the most universal, also for
people who like to jump on a bike. The shock absorbs
energy when hitting a punch, so some riders prefer to
increase compression damping. The extreme setting is
the least used, most oen 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 first half of the shock
travel, mainly when braking, negotiating steep descents,
rides, or moguls. Increasing it improves the eiciency 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 aects the second
half of the stroke of the shock from the middle of the
deflection to the moment of compression. Typically, less
experienced riders do not use this adjustment and it re-
mains in the open position. Users who like to ride more
aggressively, forcing the suspension to work quickly, af-
ter hitting a large obstacle will feel that the suspension
dives too quickly to the end of the stroke, they can coun-
teract this phenomenon by increasing the damping of
quick compression.

FORK
The Blackbird is designed to work with Enduro / FR
forks with a single crown and 160-170mm travel, while
the Junior version is for forks with 130-140mm travel.
The Bluebird is designed to work with Trail / Enduro
forks with a single crown of 130-150mm of travel. Us-
ing other types of forks or a rear swingarm with greater
travel can damage the frame, injure the user or even
kill him.
REAR SHOCK
Blackbird from the 2021 season is designed to work
with Enduro / FR shocks measuring 230 x 65 mm,
while until the 2020 season the frame was compat -
ible with 216 x 63 mm (8.5 x 2.5 ”) shocks. From the
2020 season, Bluebird is designed to work with Trail
/ Enduro shocks (210 x 50 mm), and until the 2019
season with 190 x 51 mm (7.5 x 2.0 ”) shocks. Black-
bird Junior is compatible with 165 x 38 mm (6.5 x 1.5
”) shock absorbers. Using a dierent type of damp-
er, a damper of a dierent length, can damage the
frame, injure the user or even kill him.
HEADSET
The Blackbird and Bluebird frames feature a tapered
headstock for the IS42 / IS52 headset (bottom: 52mm
inner diameter/top: 42mm inner diameter). The
frame will fit forks with standard 1-1 / 8 ”steerer tubes
or 1.5 - 1-1 / 8” tapered steerer tubes. Importantly,
you should not cut the steerer too low. The process of
assembling the rudders in the frame should be per-
formed by a qualified mechanic.
BOTTOM BRACKET
The frame is designed to work with a BSA / ISO73 bottom
bracket only and accepts conventional threaded outer
bottom brackets such as SRAM GXP, Shimano BB73, or
FSA MegaExo. Before installing, make sure the bottom
bracket shell is clean, lightly greased, and free from dirt
and paint. The installation process should be carried out
according to the instructions of the cartridge manufac-
turer.
SPROCKET SIZES
The frame is designed to work with the 34T sprockets.
The maximum size of the sprocket is indicative only. May
vary by manufacturer, model, cranks, and bottom brack-
et used.
TIRES
Blackbird 29 ”, 27.5” and 26 ”JR are compatible with tires,
with a maximum size of 2.5”. Bluebird works with tires
with maximum dimensions of 2.4 „for the 29” version
and 2.8 „for the 27.5” version. Note that these numbers
are indicative as the size and shape of the tires may vary
depending on the manufacturer and the width of the rim
on which it will be mounted.
BRAKE COMPATIBILITY
The Blackbird 29 ”and 27.5” and Blackbird Junior brake
mounts are Post Mount 160 compatible. The Blackbird
29 ”and 27.5” maximum brake disc size is 203mm and
the Blackbird Junior is 180mm.
8. GENERAL INFORMATION
SEATPOST AND SEATPOST CLAMP
The frame works with 30.9mm seatposts. Internal armor
routing for dropper posts is available. Do not extend the
seat post above the minimum extension mark. The diam-
eter of the clamp on the seat tube is 34.9 mm.
WARNING: It is important to make sure the rear tire does
not touch the saddle when the suspension is at its max-
imum travel. To check this, you must fully deflect the
rear suspension without the spring mounted on the rear
shock absorber.

A self-adhesive set of protective films can be used for ad-
ditional protection of the downtube.
Before applying the pro-
tective film to the frame,
degrease and clean its
surface.
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 fas-
tener may tear, stretch, distort or break the thread.
Either way, incorrect torque can damage the com-
ponent, 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 bi-
cycle mechanic.
See the instructions of the suppliers of the suspen-
sion 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 de-
fects may be dangerous to health and life. If you are
not a qualified 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 specified
torque. If you re-adjust, take particular care when
re-tightening. DO NOT lubricate any of the pivot
points. The factory uses high-quality self-lubricat-
ing Teflon.
Tightening torques (Nm) for individual points on the
frame:
• rear shock mounting: 10-12 Nm
• suspension system bolts: 10-12 Nm
• rear wheel axle: 20 Nm
• rear brake mounting: 10 Nm
• derailleur hanger: 20 Nm
• seat post clamp: 6 Nm
• Remaining tightening torques:

ACCESSORIES:
The rocker arm neoprene tube protector should be
wrapped together with the rear derailleur cable to
protect the rocker arm from chain impacts.

The outer protector should be secured with zip ties to
the top of the lower tube, inside the shock cage. For both
Blackbird and Bluebird frames, the brake cable should
run along the chainstay and then along the swingarm on
the opposite side of the drive to the brake caliper. The
rear shock must be removed for this operation. For the
Bluebird, the rear derailleur shell should be routed di-
rectly along the chainstay and then towards the drive
end rocker tube to the derailleur.

11. INTERNAL CABLE ROUTING
The Blackbird frame has the option of routing the
cables inside. On the le side, there is a grommet
for inserting the rear derailleur casing. The routing
ends at the bottom bracket of the front triangle,
then runs outward along the lower rocker tube. Ad-
ditionally, with the same grommet, it is possible to
insert the dropper post cord.
There is also an option to route the Seatpost cable
to the outside of the frame along the brake cable
over the top of the chainstay. To guide the seat post
cable inside the seat tube, the frame has a hole
around the center of the bottom bracket (viewed
from below).
The Bluebird frame has no internal cable routing.
All cables are routed through the top of the trian-
gle head tube. The frame has only a grommet for
inserting the dropper post cable into the lower part
of the seat tube from the damper side. Unlike the
Blackbird, the mount for the brake cable and rear
derailleur shell to the control arm on the Bluebird is
at the top of the swingarm.
• Rear derailleur cable
• Dropper post cable
• Rear brake cable (always routed outside)
