Spring

The stiffness of the spring should be adapted to your weight and your bike. During your order you have
informed the model of your bike and therefore you get the recommended spring by our studies. Please refer to
the "Chart list" available in the download section of www.bos-suspension.com for more details on available
springs.

Preload

The spring preload determines the riding height of your bike. Please refer to the "Chart list" available on our
website to know the preload settings recommendations in accordance with your bike, your weight and your
spring model.

Standards adjustment

To start your adjustment, turn the knob clockwise until it stops (= click 0). Then, clicks are
counted turning the knob in the anticlockwise direction.
