DT Swiss Ratchet DEG DF Anti-Pedal Kickback System Kit

Description

Degrees of Freedom

The DT Swiss Ratchet DEG DF Anti-Pedal Kickback System is an upgrade kit retrofittable to all DT Swiss Ratchet DEG freehub systems. DF technology releases the pedal kickback at the point where it occurs: in the freehub. This prevents unwanted chain pull during compression before it reaches the crank via the chain and negatively affects the rider. This results in improved downhill riding behavior with natural feedback from the trail and bike without the influence of unwanted chain pull. Lighter than other solutions, you simply have to replace the hubs threaded ring and the two ratchets to enjoy three different degrees of freehub movement: 0°, 10° and 20°.

Easily adjustable, low maintenance and adding no weight, DF technology offers additional degrees of freedom in tuning the riding characteristics of your bike. By allowing the freehub to rotate a specific range before engaging, the influence of the chain on the rear suspension is reduced, allowing the suspension to work freely. The system gives you the freedom to find the right setup for different types of terrain or bikes without using any tools. And if your goal is to optimize your bike kinematics, you have another degree of freedom.

For a suspension system to absorb a succession of shocks and not pull on the chain, an additional movement is required that does not influence chain tension and can reset itself quickly. To reset the DF system, you don't need any additional components. It's simply the rotation of the wheel during freewheeling and the drag from the pressure of the springs on the ratchets that forces the DF system backwards into reset or disengaged mode. As soon as the chain is moved forward by pedaling or chain pull through the frame suspension design, the DF system can move forward a specific degree of freedom without transmitting force. It thus prevents pedal kickback caused by the frame suspension design. At 0° the high engaging hub functions per usual. When adjusted to your preferred degrees of freedom, and as long as the system is freewheeling, it will be able to act as an anti-pedal kickback device.
