1. INTRODUCTION Thank you for purchasing a Bos Void shock. Your shock has been assembled specifically for one bike - obviously yours ! - which means that the internal valving and the air chamber volume are settled for your bike. The adequate mounting kit is also provided with the shock. CAUTION Never try to disassemble your shock. Limit yourself to the instructions given in this manual. This shock is pressurized, for your own safety, do not try to open it.
3.2. AIR CHAMBERS BALANCE 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. 11mm 3.3.
3.2.1. Low Speed compression (A) The low-speed compression affects the shock’s performance in compression over small bumps or through the beginning of the travel. It can be useful to make the low-speed harder (screw clockwise) on rolling terrain with big compressions and kickers. It can be useful to make the low-speed softer (screw anti-clockwise) on steep gradients. A B 3.2.2. High Speed compression (B) The high-speed compression acts mainly on harsh hits (jump landings, rough rutted sections).
3.5. AIR VOLUME ADJUSTMENT The progressive adjustment featured on the Void allows you to act on the air spring rate on the last third of stroke. Therefore, from satisfying settings (air pressure and hydraulic) on the first half of the stroke, you can act on the last mm of travel. The most featured and simple cases are : 1.
3.6. AIR VALVE ROTATION The schrader valve can rotate around the air chamber, but also be placed forwards or backwards, in order to fit into any kind of frame. CAUTION Never place the valve in front of the reservoir. This could damage seriously your shock on the first compression In order to adjust the position of the air valve to the front or to the rear or just rotating it, please follow the procedure: Procedure 1. Install the shock in a vise using a soft jaws (1) 1 2 3 4 2.
6. Before screwing back the cylinder, make sure that the rebound knob and the sticker of the main cylinder are perfectly aligned (5). 5 6 B ! 7. Once tighten, make sure that the cylinder (A) and the top of the air chamber (B) come at the same level (6). In case not, check if the valve cylinder is well positionned. A 4. MAINTENANCE Cleaning Clean your shock after each ride using a non-aggressive, non-alkaline cleaning product, let it dry then spray with silicon spray and protective grease.
5. FAQ What is the basic set up ? Your shock has been set up for your bike, with a specific internal valving and a specific air chamber volume. It is delivered with a standard pressure of 80 to 100psi. You can find in the download section of our website all the infos about standard settings for each bike. There is air leaking when I connect the high pressure pump, what can I do ? Check your pump : make sure that the shell of the shrader valve is correctly mounted.
