OVERVIEW & SPECS
WHY Topaz 2?
The Topaz 2 is the latest iteration of the Topaz Air series. This shock has been optimized to suite the needs of modern suspension kinematics working off a lower leverage ratio. The HV (high volume) negative reduces the breakaway force to counteract the a lower starting leverage force from the linkage design. The housing is designed around a transverse reservoir layout to aid in oil flow and achieve more frame clearance.
The Topaz 2 is available in metric trunnion sizes with T3 compression, dynamic rebound, positive/negative volume adjust, and adjustable bladder pressure.

Air Volume Tuning
The new Topaz allows you to tune the volume in both the positive and negative side to achieve a more progressive or linear feel. This is done with the provided tuning bands that come with your DVO Topaz. The tuning bands can be installed in the shock in a matter of minutes and in some cases without having to remove the shock from the bike.
Cooling fins on the reservoir keep the shock running cool and consistent in the harshest conditions. The small reductions in material allow heat to dissipate quicker to manage the build up of heat. The shock will retain compression and rebound damping for a longer amount of time offering ultimate performance on the roughest terrain.
T3 Compression adjust
“On the Fly” compression makes it quick and easy to switch into the various compression settings. Open for rough descents, mid for added support, and closed for the firmest compression.
Bladders are located in the reservoir of the rear shock and take the place of a traditional IFP or internal floating piston. They both have the same purpose but completely different ways of executing it. That purpose is to seperate the air from the oil. A bladder is basically a ballon which is filled with air and seated to the end cap. The bladder is filled with a high PSI to push back against the oil which creates pressure in the system. As the shock is compressed, oil flows through the the system and starts to compress the bladder.
When the shock goes to extend again, the bladder pushes the oil back in the opposite direction. This decreases the chances of what’s called cavitation. Cavitation is when there is a gap in the oil caused from air bubbles and creates a temporary loss of damping. Here’s an example of cavitation. Picture turning on a hose, what happens as the water is pushing the air out of the line? Water intermittently shoots out in between gaps of air. This same situation happens in suspension causing a loss of damping.
The real benefit of using a bladder over an IFP is when the shock is working dynamically or in “riding situations”. As the shock is compressing and rebounding at a high velocity, it can sometimes have a difficult time changing directions. An IFP usually has a moment of hesitation in that situation due to stiction between the outer O-ring and the inside surface of the reservoir. With a bladder that can’t happen and you get unmatched small bump sensitivity with a seamless transition from compression to rebound.
Every detail matters. The exterior of the shock is machined and forged with the highest quality materials available, giving the shock a brilliant and durable finish.
