CHIN STRAP
CHIN STRAP
Depending on the various versions and the
country concerned, your Spartan GT Carbon -
Spartan GT is equipped with a chin strap with
a "Precise Lock" rapid buckle with a snap lock
or one with a double-D ring. Proper use of the
chin strap is critical for proper performance of
the helmet. Never alter your chin strap in any
way. For example, never cut it or add holes, or
apply buttons, studs or other items to your chin
strap. During the life of your helmet, be sure that
the chin strap never suffers any type of abrasion
or cut, and that its total length does not change.
If it does, replace your helmet.
PRECISE LOCK
The «Precise Lock» system with ratchets
enables making fine and accurate adjustments
to the helmet fit, thanks to the extended length
of its notched part.
At the time of purchase however, it is essential
to adapt the chin strap length to your head
shape. Modify the strap length using the adjust-
ment buckle (see Figs. A through D).

Slip on your Spartan GT Carbon - Spartan GT
helmet and activate the locking system. When
the «Precise Lock» is set in intermediate posi-
tion, the chin strap must be tight enough under
the chin to provide firm support of the helmet,
yet without causing any discomfort or pain.
To lock the chin strap in place, simply insert
the tab into the designated slot on the buckle
until reaching the preferred level of tension
(see Fig. E). The tab automatically engages and
locks in place.
To unlock the chin strap, the lever arm needs to
be pulled (Fig. F) and the tab released from the
buckle. Even though the notched tab allows for
fine-tuning upon each use, it is still important
to frequently verify the correct strap length
setting.
WARNING! Never ride with the chin strap
unfastened or insufficiently tensioned,
even if the inside padding provides you with
a feeling of support: the helmet may come off
during a fall.
Never apply lubricants, acid, grease or solvents on
any chin strap buckle component.
