Back Assembly
User manual introduction
Front Assembly
Welcome to the world of Leatt® and thank you for choosing our product. The Leatt-Brace® you have
purchased is based on years of academic research and extensive evaluation of the mechanisms of
head and neck injuries, together with testing in test facilities and via simulation software. The brace
has been tested using various static and dynamic tests. The Leatt-Brace® is part of the protective
equipment ensemble available for use by participants in cycle and motor sports activities.
The design rationale behind the Leatt-Brace® is to help bring the head to a controlled stop during
an accident/fall. This is achieved by providing a padded rigid structure that helps act as an
alternative load path for neck forces. Helmet impacts otherwise transmitted from the helmet to skull
and then to the neck are re-directed from the helmet to the brace and then to other body structures.
The design of the Leatt-Brace® helps prevent the helmet/head from projecting over the brace and
therefore helps prevent a fulcrum action which has been documented in literature pertaining to the
use of collar devices. The Leatt-Brace® may be worn with most types of bicycling body armor and
chest protectors. Over long distances, the Leatt-Brace® will also offer some relief from neck fatigue.
The Leatt® DBX neck brace system helps prevent the following extreme movements:
• head, forward – HyperFlexion
• head, rearward – HyperExtension
• head, sideways – Lateral HyperFlexion
• head/helmet, rearward on the neck – Posterior HyperTranslation
• coupled axial loading – Helps prevent axial loading only when the axial forces act in
combination with other mechanisms.

Leatt-Brace® sizing chart
Sizing Chart
The size of the brace should be correct for your body shape and allows for adjustability to ensure
correct fitment and comfort, no matter what your application is.
Size Range
Small: 4 - 16 years old (thin build) to fit wearer height: 97.5 – 165 cm
Medium: 16 years + (average to bigger build) to fit wearer height: 165 cm +
When correctly-adjusted and worn with your helmet, the Leatt-Brace® should allow the full range of
normal head and neck movements (i.e. looking up, looking down and looking side-to-side, such as
when performing an over-the-shoulder check); the Leatt-Brace® and the helmet should only come
into contact with each other as the full range of normal head movement is reached.
If any resistance or discomfort is experienced when attempting to complete the full range of head
and neck movements, or if the brace does not make contact with the helmet when the full range of
movement is reached, further adjustment, or an alternative size of Leatt-Brace® may be required.
In extreme circumstances, it may be necessary to purchase an alternative model of helmet in order
to achieve the required level of compatibility and safety.
Please ask the retailer or contact Leatt® if you require further advice on sizing, adjustment or fitting.
Please use the sizing chart below to ensure that you have purchased the correct size Leatt-Brace®.
The sizing chart is based on your height and chest circumference right below the arms therefore
make sure that you take the correct measurements before utilizing the chart on next page.

Leatt-Brace® fitment - Step 1
The brace has been fitted on a wide range of users and bicycle types and should fit you. If not,
minor adjustments may be required for proper fit. Failure to properly adjust the brace before use
may compromise rider safety and brace effectiveness. When correctly-adjusted and worn with
the user’s safety helmet, the Leatt-Brace® should allow the full range of normal head and neck
movements (i.e. looking up, looking down and looking side-to-side, such as when performing an
over-the-shoulder check); the Leatt-Brace® and the helmet only coming into contact with each
other as the full range of normal movement is reached.
Fitting the Pins
Unscrew the 2 Buttonhead Cap Screws (see Figure 4a) with the supplied Allen key. Slide the Pin
out once the Cap Screws are removed (see Figure 4b) and replace by sliding the desired Pin back
in the same way. Now screw in the 2 Buttonhead Cap Screws with its washers in place to secure
the newly fitted Pin.
Figure 4a:
Back Assembly
Your DBX Pro brace is supplied with three pairs of different sized Pins for adjustment. The Medium
Pin is fitted as standard. Start by fitting your brace without the thoracic assembly attached on your
shoulders and chest as shown below in Figure 2.

Adjustment with Pins
If the brace is too loose around your
neck with the fitted Medium Pin and does
not sit comfortably on your shoulders
and chest, fit the Short Pin (see Figure
3). If the brace is too short and therefore
too tight, simply fit the Long Pin.

Step 2 - Strut and
thoracic assembly
The Strut assembly has three parts,
the thoracic strut (Figure 6) and
two rotatable wedges (Figure 6a).
Depending on the configuration of the
the wedges and the thoracic strut, you
can vary the fitment angles to 5O, 10O
or 15O, see (Figure 6b)
Figure 6
Step 2 - Strut assembly
(Continued)
Insert the strut assembly (Figure 6 & 6a) into
the back assembly of the brace (Figure 7a),
starting with one Shim on either side (Figure
7b) of the strut assembly. The strut assembly
and Shim will always be contained within the
brace so that you can adjust the brace at any
time. There is no need to fit the Locking Cap
Screw at this time.
Strut locates into
back assembly
We recommend that you start with the
strut angled at 10 degrees. This is the
most commonly used strut angle for
average sized riders.

Now refit the brace. If the brace is pulled
slightly backward (too tight), place the two
Shims (Figure 7b) in front of the strut assembly
(towards the front portion of the brace), if the
brace has become too loose, place the two
Shims behind the strut assembly (towards the
back portion of the brace). If the lowermost
portion of the strut assembly is located away
from your back, use another strut assembly
combination. (refer to Figure 6b). You may now
secure the Locking Cap Screw (see Figure 7a)
that fastens the strut assembly to the
back assembly.

Partially remove front padding from brace
(Figure 9b). Insert both tips of chest strap
through the insertion points on the sides
of the front padding. Attach strap ends to
the velcro inside of the padding.
Re-attach padding to front of brace.
Adjust buckles on both sides to fit
comfortably on body (Figure 9c).
Roost Guard
When wearing a roost guard, the lower
portion of the front assembly of the
brace should be placed inside the roost
guard and the upper portion of the front
assembly should be outside the roost
guard (Figure 10a). The same applies to
the back upper and lower portions of the
brace (Figure 10b).
Velcro
If your roost guard is a smaller size, you
may have to widen the head opening
of the roost guard. Most roost guards
allow for this adjustment. In the case
of very small children, allow the front
lower portion to rest on the outside of the
roost guard. Some junior riders choose
to remove the hard outer portion of the
shoulder padding from their roost guards
for comfort.

Fitting the DBX Pro
brace with a Body
Jacket
Looking after your Leatt-Brace ®
Figure 11a
You may want to wash your Leatt-Brace® after hard riding. The brace and integrated padding
should only be washed with a gentle soap or detergent in cold water, rinsed in cold water and dried
with a cloth only. Common substances applied to this brace (solvent, cleaners, hair tonics, etc.) can
cause damage that may be invisible to the user and compromise the effectiveness/safety of the
Leatt-Brace®. Always refer to the material content label on the Leatt-Brace®. None of the materials
used are known to contain anything that might cause an allergic reaction or be dangerous to
your health.
Body Jacket
The DBX Pro Brace can be worn very
comfortably and unobtrusively with a
Body Jacket. When wearing a Body
Jacket with the brace, ensure that the
brace rests comfortably over the front
of the jacket.
(see Figure 11a).
When storing your Leatt-Brace®, place it on a clean, dry surface and store in a dry, well-ventilated
environment away from direct sunlight and extremes of temperature. Do not place heavy objects on
top of the Leatt-Brace®.
At the back of the jacket the thoracic
assembly should be worn on the inside
(see Figure 11b).
For maximum performance the Leatt-Brace® must be inspected prior to each use. Stop using the
Leatt-Brace® if any of its components, including but not limited to, the Front Component, Hinge
Lever Assembly, Pins, Strut, Nylon Washers and/or the Back Component (See Parts/Components
List on page 3) are worn, cracked and/or deformed, or if the inside padding is deteriorated.
Refer to Step 1 to adjust the fit and
comfort of your brace on the chest
and back.
We wish you many safe hours of enjoyable racing and riding with your Leatt-Brace®. Please
contact us with any questions or comments at info@leatt-brace.com. We recommend that
you replace your Leatt-Brace® every two years of normal racing conditions and replace any
components that are damaged in a serious accident.
