MOD SHOCK SAFETY GUIDELINES
• MOD shocks sets produced by FORMULA S.a.S are designed exclusively for use on
two wheels bicycles. Any other use is to be considered hazardous. FORMULA S.a.S
shall not be held liable for any consequences from improper usage.
• The lifespan of MOD shock depends on many factors, such as rider size and weight,
spring and frame used and normal wear and tear on the bicycles.
• Check the condition of the spring regularly and replace it when necessary.
• Impact, falls, excessive, improper or harsh use of the bicycle may compromise the
structural integrity of the shocks, significantly reducing their lifespan. Short life-
wheel components need to be replaced more often.
• Have the shock regularly inspected by a qualified mechanic for any cracks, deforma-
tion, signs of fatigue or wear.
• If inspection reveals any deformation, cracks, signs of impact or stress, no matter
how slight, immediately replace (not repair) the component. Excessively worn com-
ponents also require immediate replacement.
• The frequency at which inspection is required depends on many factors. Ask a FOR-
MULA S.a.S dealer to recommend an inspection and service schedule that is right
for you.
• Use of the product by individuals who weigh more than 120kg/265Ibs is not recom-
mended. If you weigh more than 120kg/265Ibs be especially careful and have the
bike inspected more frequently.
• Parts which have been bent or damaged in an accident or as the result of impact,
must be immediately replaced with genuine FORMULA S.a.S replacement parts.
• Check with a qualified mechanic to ensure that the selected MOD shock is suitable
for the required type of use and to establish an inspection and service schedule that
is right for you.
• Tools supplied by other manufacturers for wheels similar to MOD shock may not be

compatible with MOD shock. Likewise, tools provided by FORMULA S.a.S may not be
compatible with components/wheels supplied by other manufacturers. Check with a
qualified mechanic or 5 tool manufacturer to ensure compatibility before using tools
supplied by one manufacturer on components/wheels supplied by another manu-
facturer.
• Failure to verify compatibility of the tools may cause the component to work incor-
rectly or break, resulting in an accident, personal injury or death.
• The user of MOD shock expressly recognizes that there are risks inherent in bicycle
riding, including but not limited to failure of a bike component, resulting in an acci-
dent, personal injury or death.
• By purchasing and using these MOD shock, the user expressly, voluntarily and know-
ingly accepts and/or assumes these risks, including but not limited to the risk of
passive negligence on the part of FORMULA S.a.S, i.e. for hidden, latent or obvious
defects and exempts FORMULA S.a.S from liability to the fullest extent permitted by
law against any resulting damage.
• Ensure there are no damaged or loose hardware.
• Always make sure that the shock is marked “MOD”.
• Make sure the shock is true before use.
• Carefully read the FORMULA MOD shocks instructions before use.
• Carefully follow the scheduled maintenance program as indicated in the relative para-
graph.
• Always use genuine FORMULA S.a.S replacement parts.
ENVIRONMENTAL NOTES
In order to protect the environment, please follow these simple instructions to cor-
rectly dispose of FORMULA S.a.S products:
1) The packaging does not require special disposal because it is not dangerous in any
way; we suggest recycling paper and plastic.
2) It is also recommended to recycle the metal parts after use. For both points men-
tioned above, it is recommended to dispose of the waste following national regula-
tions through the appropriate specialized waste disposal companies.
CHECK BEFORE EVERY RIDE:
In order to guarantee your health and maximum enjoyment, check before every ride
that FORMULA MOD shock absorber is ready.
• Make sure the shock absorber is clean: using water and neutral soap, clean the out-
side of the suspension by hand. Subsequently, after a splash of water, act with a dry
and soft cloth to remove the residues;
ATTENTION: do not use solvents or degreasers. They can damage external sur-
faces. Do not use high pressure water sprayers directly on the shock absorber
joints, in particular near the hydraulic seals which could be seriously damaged and
compromise the functioning of the suspension.
• Inspect the outside of the shock absorber. Check if there are no breakages and / or
damages. If present, contact the FORMULA dealer immediately for inspection or re-
pair. Do not use the shock absorber in this case.
• Make sure that the frame coupling screws are tightened to the correct tightening
torque as recommended by the frame manufacturer. The hardware does not play
with the coupling screws. If yes, immediately replace them, see manual at
paragraph “b”.
• Also make sure that the coil spring is properly preloaded as recommended by para-
graph “e”.

1.9 Problems - Causes - Remedies
1.1 Formula hardware installation:
Formula hardware kit may differ depending on the customer’s request regarding its
frame. The bushings (DU) are already installed on the rear shock absorber.
For STANDARD attack shocks, the kit includes (figure A):
a) n.2 assembly pins;
b) n.4 spacers;
c) n.4 Orings;
For TRUNNION shocks:
a) n.1 mounting pin;
b) n.2 spacers;
c) n.2 Orings.
ATTENTION: The screws for the TRUNNION connection are supplied by the
frame manufacturer. FORMULA assumes no responsibility for damage or mal-
functions due to the condition of these screws.

INSTALLATION PROCEDURE (do the same also for the opposite part of the shock):
1) Insert the pin into the eye of the shock (figure B);
2) Insert Orings in the seats of the spacers: apply Formula grease on the OR seat (figure
C), then insert and check the homogeneous adhesion to the surface of the groove.
Then apply Formula grease on the OR too (figure D);
3) Inserting spacers on mounted pin (figure E);

1.2 Installing shock on a MTB frame:
ATTENTION: Suspension setting should be different between different bi-
cycle manufacturer. All maintenance operations must be carried out solely by
personnel authorized by FORMULA S.a.S.
FORMULA assumes no responsibility for breakages and damage to people and / or
things due to this non-compatibility. The result of such non-compliance can lead
to DEATH. Contact the FORMULA Dealer and don’t use the shock.
WARNING: FORMULA recommend DO
NOT INSTALL THE SHOCK on frame
with the eyelets as showed in figure on
the left. The axes of the eyelets MUST
BE perpendicular to the same plane as
showed in figure on the right.
FORMULA assumes no responsibility for
breakages and damage to people and / or
things due to non-compliance. This is valid
until further notice.

If MOD shock is not already supplied on the bicycle, it’s necessary check the frame
compatibility:
1) Remove the spring from the shock as written in paragraph “e”;
2) Install the Formula hardware on the shock as written in paragraph “b” according to
the specific measures of the frame;
3) Insert MOD shock into the frame and tighten the screws of it (figure F).
4) Slowly Compress and extend the rear part of the frame making the whole stroke.
Inspect if there is interference with the frame (figure G);
5) Remove the shock from the frame;
6) Install the spring with the correct preload as showed in paragraph “e” and install
MOD shock.

1.3 SAG and adjustments:
Detecting the SAG can be useful to have an initial idea of the response of the shock
absorber (complete with spring) with respect to our weight and the cycling discipline
that you want to practice.
Here is the measurement procedure:
a) Measure the distance between the two
eyelets of the shock absorber (eye-to-eye,
in mm) of the rear shock absorber moun-
ted on the bike (figure H).
b) Wearing your own complete
equipment for MTB output
and with the help of a per-
son, position yourself on
the bike in a normal riding
position and measure the
distance between the two
eyelets which will necessar-
ily be decreased (figure I).
c) Taking these two measurements, calculate the SAG;
Example: MOD shock, Length x Stroke: 230x65 mm. 1° measure: 230 mm;
2° measure: 210,5 mm;
Difference between the measures: 19,5 mm.
Use this formula: SAG(%)=
(230 - 210,5)
(Shock stroke) x 100
Fig. H
Fig. I
10
The result is 30% of SAG. Here below is a reference table for measurement:
STROKE 15%SAG 20%SAG 25%SAG 30%SAG 35%SAG 40%SAG
55 mm 8,25 mm 11 mm 13,75 mm 16,5 mm 19,25 mm 22 mm
65 mm 9,75 mm 13 mm 16,25 mm 19,5 mm 22,75 mm 26 mm
75 mm 11,25 mm 15 mm 18,75 mm 22,5 mm 26,75 mm 30 mm
FORMULA recommends 30% of SAG for the Enduro / Gravity discipline. For the trunnion
attack, it will have a different length but the calculation formula remains the same.
ADJUSTMENTS:
If the SAG is not the desired one, here’s how we can operate (figure J):
• To increase the value of SAG, need
to decrease the preload: rotate
with the RIGHT hand the preload
nut COUNTERCLOCKWISE (blue ar-
row), taking care not to drop below
the minimum preload value (2 mm).
If this does not allow the desired
value to be obtained, a lower stiff-
ness spring (lbs/in) must be used.
• To decrease it instead, rotate the
threaded ring CLOCKWISE (orange
arrow) making sure not to exceed
with the preload in addition to the
maximum allowable (5 mm). Here
too, if we fail to obtain the target
value, it will be necessary to change
the spring with a higher stiffness.
For the coil replacement consult paragraph “e”.
