GASGAS DVO WP Onyx 38 - Setup Guide Owner Manual

Failure to comply with these warnings and instructions may cause SERIOUS
INJURY, DEATH, or DAMAGE TO YOUR PRODUCT.
Be sure to read this manual carefully before using your DVO suspension. Throughout this manual,
reference is made that “an accident” could occur. Any accident may cause damage to the product,
SERIOUS INJURY, OR DEATH.
These instructions contain important information about the correct installation, guidelines for setup, service and maintenance of your suspension. Nevertheless, please be informed that special
knowledge and tools are essential to install, service and to maintain DVO Suspension. Common
mechanical knowledge may not be sufficient to repair, service or maintain your suspension. Therefore we strongly recommend getting your suspension installed, serviced and/or maintained by a
trained and qualified bicycle mechanic. Improper installation, service or maintenance can result in
an accident.
Forks and rear shocks contain fluids and air under extreme pressure. DO NOT attempt to disassemble any portion of a DVO Suspension product unless instructed to do so by a DVO Suspension
authorized technician.
PRE-RIDE SAFETY CHECK
1. DO NOT ride your bicycle if any one of the following test criteria is not passed! Riding your bike
without eliminating any defect or carrying out the necessary adjustments can result in an accident,
SERIOUS INJURY OR DEATH.
2. Do you notice any cracks, dents, bent, or tarnished parts of your suspension fork or shock, or any
other part of your bicycle? If so, please contact a trained and qualified bicycle mechanic to check
your fork, shock, seat post, saddle, and complete bike.
3. Do you notice any oil leaking from your fork and/or shock? If so, please consult a trained and
qualified bicycle mechanic to check your suspension and bike before riding.
4. Make sure your wheel is attached and centered properly in order to avoid any contact with the
suspension fork or brake system.
Only use genuine DVO Suspension replacement parts. Modification, improper service, or the use of
aftermarket replacement or spare parts may result in an accident and VOIDS the warranty of your
product.
5. Make sure your axle system is secure. There should be no play between the hub and fork lower.
DVO Suspension forks and rear shocks are designed for the usage by a single rider only.
6. Make sure your brakes are properly installed, adjusted, and work properly. This also applies to
every other part of your bike like handlebars, pedals, cranks arms, seat post, saddle, etc.
DO NOT use DVO Suspension products on any powered vehicle that is not a pedal-assist Class-1
or Class-3 e Bike.
Always be equipped with proper safety gear. This includes a properly fitted and fastened helmet.
According to your riding style you should use additional safety protection. Make sure your equipment is in flawless condition.
7. Check the cable length and routing of your braking components. Make sure they do not interfere
with your steering actions or full compression and extension of your suspension.
8. Check your shock hardware and ensure there is no play between the shock and mounting surfaces.
Ensure your shock hardware is tightened to the bike manufacturer’s recommend torque before riding.
Make sure you select the correct fork and rear shock according to your frame manufacturer specification. Installing suspension that does not match the geometry of your frame could result in a
failure of the suspension itself and void the suspension warranty. Installing a fork or rear shock not
designed for your frame will change the geometry and handling of your bike. Learn how to ride and
train your skills. Know your limits and never ride beyond those.
Study all other manuals provided with your bicycle and make yourself familiar with all components
mounted to your bike.

SOME HELPFUL TIPS BEFORE YOU GET STARTED
SAG Indicator
O-Ring
1. All of these settings are just starting points to get you close. Don’t be afraid to use your adjusters
or change up your settings to make it perfect for you.
2. Write down your settings! Modern suspension forks have a ton of adjustment which is awesome,
but you can get lost. When you find a good spot, write it down so you can always go back to it.
3. Dedicate time to setting your bike up for the trail, not the parking lot. It’s a good idea to get out
on the trail and find a section you can repeat. Try different settings to truly feel what the adjusters
are doing. Once you truly understand what they do and feel like, you’ll know when to use them in
any situation.
4. Balance is key! This is a big one. Try your best to get your fork and shock feeling equal. If the
rebound in the rear shock is way faster than the fork, the bike won’t have a very predicable ride. Feel
to make sure the rebound, spring rate, and compression are having similar feelings front and back.
This will provide a predictable and confidence inspiring ride.
5. If you have questions, don’t hesitate to ask. Give us a call, shoot us an email, we’ll get you dialed in!

OTT Feature
What is OTT?
Adjusting the OTT Feature
OTT stands for Off the Top and is a
DVO Exclusive Performance Feature
that delivers amazing traction, comfort
& control matching a wide range of
riders weights & skill levels. OTT allows
the rider to fine tune the small bump
sensitivity without affecting the midstroke or end-stroke.
Our D1/E1 models come with an externally adjustable OTT. This is a 5mm allen key adjustment
located on the bottom of the left fork leg. When adjusting the OTT, go by full rotations not by clicks.
IMPORTANT
Let the air out of the fork before adjusting OTT!

Tech Tip!
As a general rule of thumb, the heavier or
aggressive rider will use more air pressure &
more OTT. A lighter or less aggressive rider will
use lower air pressures and less OTT.
6
Heavier Riders = More OTT
Lighter Riders = Less OTT
How does it effect the ride?
Higher air pressures allows fast moving riders to skip over bumps and holes but the downside is the
harshness. With the OTT feature, the initial 30mm’s of travel can be independently tuned regardless
of air pressure. Heavier or fast riders can run higher air pressures while still having amazing small
bump sensitivity & traction by simply increasing OTT. Lighter riders who run lower air pressures will
use less OTT allowing use of all the travel without having the fork sack or hammock in the middle
of the stroke. The Best of Both Worlds!

SAG is the amount your fork compresses under your body weight
(don’t forget to include your riding gear), also referred to as
Rider Weight. Remember that these are only starting points and
adjustments will vary based on rider ability, trail conditions and
personal preference.
After you are done setting up your suspension fork according to the
recommended base settings, check your SAG to make sure you
are within the recommended SAG settings.
SAG Range
The recommended SAG is 15% - 30%. Setting proper SAG is the
only way to find the right air pressure for your fork. Refer to the
chart below to find the proper SAG.
Can SAG effect the handling
of my bike?
It is very beneficial to test different SAG settings for various riding conditions. Changing the amount
of SAG on your fork will change the geometry of your bike.
Riders that make high speed stability a priority can run less SAG. This will keep the front end of the
bike high under braking and rough sections but comfort and cornering traction will be
compromised.
Riders that want to have a comfortable ride with great cornering traction should run more SAG
(around 30%).
If you're enjoying your fork on a E-Bike, you may need to increase

Rebound
Rebound Base Setting Chart
What is Rebound?
Air Pressure
Rebound controls the speed at which the fork extends after compression. Rebound damping
control is relative to the amount of air pressure used.
Start with your rebound closed (all the way clockwise) then adjust out to make it faster.
Each click out (counter-clockwise) is your rebound setting. Use the chart to find a good
starting position.

Slowest Rebound Setting
(Clockwise)
If rebound is too fast, your wheel will fall into more holes, instead of skipping over the top of them.
Handling will feel twitchy and hard to control, it will be easier to be thrown out of control on jumps
and landings.
If rebound is set too slow it will pack on successive hits because the fork cannot extend fast
enough keeping you in the mid stroke. This will result in the wheel going deeper into the travel on
every hit and riding towards the end stroke. The result will be a harsh feeling and loss of traction.

About High Speed Compression
High Speed Compression damping affects the suspension when the shaft is moving up and down
at high speeds. High Speed Compression helps with large impacts or sharp/sudden impacts. High
Speed Compression can be used to reduce bottom.
Too much High Speed Compression may result in the fork not being able to reach full travel,
and or spiking on large impacts.
If you don’t have enough High Speed Compression, The fork will blow through it’s travel too easily
on jump faces, and will bottom out to easily on large impacts.

Low Speed Compression
Axle Installation
Adjusting Low Speed Compression
Your new Onyx 38 comes with a floating axle system. Proper installation is extremely important for
safety and function. Follow the steps below to perform installation correctly.
The D1 models have an adjustable low speed
compression. Rotate the LSC knob (black color)
counter-clockwise until it stops and this is the open
or “softest” setting. Each clockwise click is a firmer
setting to increase support.
1. Loosen pinch bolt with a 5mm allen key and install the wheel into the dropouts. Insert the axle
into the drive side dropout and hub.
2. Tighten the axle with a 5mm allen key to 12 Nm.
3. Compress the fork multiple times to ensure proper alignment.
4. Tighten the pinch bolt on the drive side dropout to 5 Nm
What is Low Speed Compression?
Low speed compressions controls the slower vertical movements such as climbing or slower paced
trails and bumpy whoop sections. A good example of low speed is rolling slowly over a large rock
and riding to its downside, this is where the suspension will fully compress but at a slower rate and
low speed compression circuit comes into play. LSC refers to the shaft speed of the suspension
and not the actual riding speed. LS compression is best controlled through a low speed oil circuit
and or shim stack.
Drive Side
Non-Drive Side
Axle
Too little or too much LSC
Pinch Bolt
Too much Low Speed Compression will result in harshness over small bumps and traction will be
reduced. Turning performance may also suffer because the suspension will ride too high in its travel.
The ride may become harsh.
Not enough Low Speed Compression will result in the front end diving to quickly under braking.
The suspension will have a mushy feeling and may bottom out too easily.
Tech Tip!
Frequently check the torque of your pinch bolt. This can drastically effect the
performance and safety of your fork.

Mounting Disc Brakes
Air Volume Tuning
Your new Onyx 38 comes with a 203mm post mounts to allow you to bolt your caliper directly to
the fork and utilize a 203mm rotor.
Changing volume spacers is an easy way to tune the air spring of your Onyx 38 fork. This can
provide an increase in mid-stroke and bottom-out resistance.
If using a different sized rotor (not 203mm) , you will need to source the appropriate caliper spacer
and bolts. Contact the brake manufacturer for further information.
How do I know when to use a volume spacer? Always start with your SAG as the reference point.
If SAG is set correctly and you are using full travel too easily, install one volume spacer and test
ride. Repeat until the appropriate travel is used. A maximum of 4 volume spacers can be used.
How to install Volume Spacers
NOTE: Air volume spacers should only be used in “SL” model forks.
2x M6 x 1,0
1. Make sure your fork is clean and free of any dirt or contamination.
2. Release ALL air pressure from fork.
3. Using a cassette tool, loosen air side top cap (A) and remove.
Disc brake caliper mount
bolts must have 10-12mm of
thread engagement.
Torque bolts to manufacturer’s
specification.
4. Thread on desired amount of volume spacers (C) into the air side top cap (A).
5. Re-install air side top cap (A) into the stanchion. Tighten to 20 Nm.
6. Make sure the air side top cap o-ring (B) has sufficient grease. We recommend Slikoleum or an
equivilent grease.
6. Using a shock pump, inflate the fork to your desired air pressure.
Follow your brake manufacturer’s installation instructions for proper installation and adjustment of the brake system. Failure to properly install and adjust
your brakes can lead to a loss of control of the bicycle which can result in
SEVERE INJURY OR DEATH.
Always refer to the proper installation instructions stated above. Failure to
properly install and adjust your volume spacers can result in
SEVERE INJURY OR DEATH.

Tech Tip!
Air springs are always progressive which means the force needed to compress the
fork is always increasing through the stroke. A higher air pressure means the fork will
naturally be more progressive. A lighter pressure will be less progressive. Lighter riders
may need to use more volume spacers. And heavier riders may need to use less.
