C. THE HElMET
8. WIND DEFLECTOR
The wind defl ector prevents the unpleasant effect of the wind
created as you ride fl owing into the helmet. In addition, the
riding noise in the helmet is reduced.
1. The wind defl ector is attached
by Velcro strips on the inside of
the acoustic collar and can be
removed when required to provide
an additional fl ow of fresh air,
especially in hot weather.
Tip:
The fi t of the bottom of the helmet is extremely important in
ensuring that the helmet is as quiet as possible. If you have a
smaller collar size, we recommend that you also wear a scarf.
9. RETENTION SYSTEM
The retention system of the S2 consists of a chinstrap that is
additionally secured with neckbands at the back of the helmet
shell (the anti-roll-off system, see section C.14.).
Chinstrap with Micro-Lock ratchet fastener
The S2 comes with a ratchet fastener. This
locking system is easy to use and
enables you to adjust the chinstrap
perfectly to your head every
time you put the helmet on.

Check the adjustment of the chinstrap length at regular
intervals (see section E.2.).
Opening and closing
