FAQ11
What is the basic set up?
Your VOID shock was delivered with intermediate external hydraulic settings and inflated to a 80 to 100psi
pressure; nevertheless you should refer to the tuning section of this manual to fit it perfectly to your bike,
your weight, and your riding style.
You can find all the information about standard settings for your bike in the chartlist on the BOS website
download section.
There is air leaking when I connect the high pressure pump, what can I do?
Check that your pump is correctly connected to the valve shell. Make sure that the Shrader valve core is
correctly tightened.
My shock is too stiff on the first inches of travel and / or the rebound is very fast. What can I do?
The two air chambers are not correctly equalized. Check out chapter 3.2 to see how to equalize your air
chambers.
Once reassembled, the shock stickers are not aligned. What can I do?
To be sure that the stickers will be correctly aligned, check out chapter 3.5.
My shock has a slight negative travel. Is that normal?
The BOS air spring is designed to lower the engagement threshold as much as possible. Therefore, it is
possible on some bikes that there will be a small negative travel.
Where can I purchase replacement stickers and valve cap?
You can purchase these items through your approved BOS center, or on the BOS store on bosmtb.com.
I noticed some play between my shock and the frame, what can I do?
Check that your mounting hardware is torqued to your manufacturer's specifications. If it is, the rear shock
mounting hardware must be replaced. Contact an approved BOS service center, or connect on BOS
website.
My shock is compressing when I deflate it, is that normal?
When you deflate your shock from the air valve, you are only deflating the positive air chamber. The
negative air chamber is still pressurized and pulls on the shock's shaft. If you want to avoid this, deflate
step by step (30 to 40psi), and balance the air chambers between each step (5 to 6 slow compressions and
extensions over the first 11mm of the shock's travel).
My shock makes a whistling or clicking sound when I compress it.
These sounds are normal to the functioning of the hydraulics when the rebound or low-speed compression
circuit is closed or almost closed. Check your settings and bring them closer to the base settings in your
product's user manual to reduce this noise.
