Update: September 9, 2015
This video explains in detail how the Fox Float DPS system works. It provides full lockout without compromising the ride control and efficiency, allowing riders to adapt to any terrain. FOX DPS provides a wide range of on-the-fly compression settings and excellent bump recovery in a lightweight package making it ideal for the new crop of more capable Trail Bikes.
The 2016 FOX Float rear shock now has two damping pistons instead of one found in the old CTD. This allows the first piston to focus on compression and rebound. The second piston is dedicated to the firm mode exclusively. So now, there is better optimization for the Open and Medium modes. The the Firm mode, well it’s really firm, giving the rider a hardtail-like pedaling platform.
The other new technology in this shock is EVOL which stands for Extra Volume negative air spring. It is a larger negative air can and it’s visible from the exterior with a noticeable bump in the middle of the shock.
It increases the volume of the negative spring, which allows the shock to move more freely on the initial stroke. It also gives the shock more mid-stroke support. And with improved suppleness in the shock, FOX was able to tune the damping of the system to give it more support.
Another welcome change is the Low Speed Compression knob now takes effect in the Open mode of the shock. This gives the rider control of performance in the state when the shock is doing its best work. Shocks after all should be optimized and tuned for absorbing shock, not for pedaling.
