Designed in Australia, the SD Components Dynamic Volume Chamber, or DVC, is a dual chamber air spring cartridge, designed to improve the performance of your fork by giving you more control over the spring curve.
Fitting it is as simple as removing the old top cap, and threading in the DVC using the laser-cut stainless-steel DVC spanner (& bottle opener), or a top cap socket.
The DVC is not just about providing ease of adjustment – it provides more flexibility over the fork’s performance, allowing greater independent control over the beginning and end-stroke.
The pressure in the main air chamber (valve 1) dictates the fork’s sag and the performance for the first half of the stroke, the pressure in the second chamber (valve 2) controls the level of mid-stroke support and the bottom-out resistance. Fine tuning the pressures of the two chambers allows you to alter the fork’s feel to suit your riding style or the terrain.
The DVC is ideally suited to lightweight and/or aggressive riders trying to get the absolute best performance out of their suspension, and the DVC makes this process both easier and more precise. Also, racers who are looking for the edge and who find themselves faced with constantly changing conditions will certainly favour the adjustability of the DVC.
The DVC is available for many contemporary single crown forks (2018 - Present), including; DVO Diamond, Fox 34, Fox 36, RockShox Lyrik, and RockShox Pike.
The Dynamic Volume Chamber by SD Components is available exclusively from Shock Therapy.
