DVO Topaz 3 Rear Air Shock

The transverse reservoir design serves two main purposes: it improves internal oil flow for more consistent damping performance and increases frame clearance, making it easier to fit on a wider variety of bike frames.

The bladder system is designed to eliminate stiction, which significantly improves small-bump sensitivity. This allows the shock to react more quickly to trail chatter, providing better traction and a smoother feel over rough terrain.

Yes, the Topaz 3 allows for independent adjustment of both positive and negative air spring volumes. This gives you granular control over the shock's progression and support, allowing you to tune it to your specific riding style and weight.

The T3 compression switch offers three distinct settings—Open, Trail, and Firm—that allow you to quickly adapt the shock's behavior on the fly. It is designed to let you firm up the suspension for climbing or efficient pedaling without needing to stop and make complex adjustments.

The Topaz 3 listed here has a length of 205 mm and a stroke of 60 mm. You must verify that these specific dimensions match the requirements of your bike frame's rear suspension design before purchasing.

You will need a standard shock pump to set your sag and adjust the air pressure, which is included with the shock. Beyond that, no proprietary tools are required for basic setup and tuning.
