The new Degrees Freedom technology against pedal kickback is extremely simple in design. DF technology eliminates pedal kickback at the point where it occurs: in the hub’s freewheel. This prevents unwanted chain pull during compression before it reaches the crank via the chain and negatively affects the rider. The result is a natural downhill riding experience with authentic feedback from the trail and bike, free from the influence of unwanted chain pull. Extremely simple system to combat pedal kickback
Easy to adjust, low-maintenance and lightweight: the new DF technology offers additional degrees of freedom, allowing you to fine-tune your bike’s characteristics in even greater detail. The freewheel system rotates up to a certain point before engaging. This reduces the effect of the chain on the rear suspension, allowing the suspension to operate more freely. With this system, you can find the right setup for different terrains or bikes without any tools. And if you want to optimise your bike’s kinematics, you have another degree of freedom at your disposal. *Degrees of freedom: the number of values that can vary freely in the final result of a statistical calculation.
In suspension systems that must withstand many successive impacts without creating tension on the chain, an additional movement is required that does not affect the chain tension and quickly cancels itself out. No additional components are required to reset the DF system. Simply the rotation of the wheel during freewheeling and the tension exerted by the spring pressure on the sprockets pulls the DF system backwards into reset or disengage mode. As soon as the chain moves forwards due to pedalling or tension caused by the frame suspension, the DF system can move forwards by a certain amount without any power being transmitted. This minimises pedal kickback caused by the frame suspension. At 0°, the quick-responding hub functions as usual. Once the desired degree of freedom has been set and during freewheeling, the system counteracts pedal kickback.
Compatible with Ratchet DEG The new DF technology is a highly simplified anti-pedal kickback system. It is available as a dedicated upgrade kit and can be retrofitted to all Ratchet DEG freewheel systems. It is lighter than other solutions, as you only need to replace the hub’s threaded ring and the two toothed discs to enjoy three different options for the freewheel’s range of motion: 0°, 10° and 20°.
