3.2. AIR CHAMBERS BALANCE
3.3. CHECKING THE SAG
The SAG is the quantity of travel used while sitting on your bike, due to the effect of your weight. It has to be settled
up by adjusting slightly the air pressure.
BOS recommends a percentage of SAG of 30 to 35 %.
The bike manufaturer may also indicate a percentge of SAG. Please refer to your bike’s owner manual to check it.
If the bike percentage differs from Bos advices, please test on the track what is the best setting for your riding style.
How to measure and set up the SAG ?
Slide the O’ring onto the seal of your shock.
Sit on your bike (if possible dressed with your riding outfit) feet on the pedals - horizontal position, and let the sus­
pension compress under the effect of your weight. Get down from the bike, extend the rear suspension to the
maximum by pulling up the saddle, and measure the distance between the O’ring and the seal. This distance will
allow you to check the percentage of SAG obtained with the current air pressure. To convert the distance into
percentage, refer to the table below.
length x stroke (mm) 222x67 240x76 267x87
SAG (%) 30 35 30 35 30 35
SAG (mm) 20 24 23 27 26 31
If the SAG is not correct, slightly set up the air pressure, by 15 PSI steps.
Too much SAG : increase the air pressure.
Not enough SAG: reduce the air pressure.
3.4. HYDRAULIC SETTINGS
The Void shock is a three-ways type shock, which means there are three types of damping adjustment: rebound,
low-speed compression and high-speed compression.
Your shock’s basic setting (internal) is designed for your bike’s geometry. We use ten base settings which cover the
majority of bikes on the market. If a different setting is necessary for a given bike, we will develop it especially.
The purpose of damping adjustments is to use all the shock’s travel without bottoming-out (or only rarely), to give
grip to the rear wheel, but also to stop the bike stalling in holes, and finally to maintain a good position. Below are
the basic settings for your frame. Then it’s up to you to analyse its performance and adjust the settings to suit your
riding style. Do this carefully and methodically, step by step. Only change one setting at a time and only by a few
clicks. If it’s OK, note the setting and type of terrain. If you get confused with the settings, return to the basic settings
and start again.
In order to guarentee a perfect functioning of
your shock, after having set up the air pressure,
you must proceed to the air chambers balance.
The shock must be mounted on the bike.
Place the O’ring at 11 mm from the seal of the
shock, sit on your bike, and push slowly on the
suspension, to compress the shock until the seal
come onto the O’ring.Let the suspension extend
itself, still slowly.
Repeat 15 times those up and down
movements, always at low speed.
