5. Secure the excess strap with O-ring and then attach the chinstrap
pad. Always wear the helmet with the chinstrap buckle fastened and
the chinstrap pulled tight and positioned back against the throat.
With the strap buckled and the helmet positioned, you should feel
the chinstrap pull firmly against your chin as you open your mouth.
When properly adjusted the helmet will wrap around your head and
cradle it with firm, but comfortable pressure.
6. Your helmet is equipped with an adjustable retention system which
helps stabilize the helmet in the correct position when you ride. When
wearing the helmet, turn the retention system knob clockwise to
tighten the helmet or counterclockwise to loosen the helmet.

retention system upward or downward to a different position.
