These steeering wheels have a transmission by gears, this causes that there is a small gap between teeth that does not transmit anything in the small movements of the force feedback and that also produces a noise like blows in the curbs of the circuit and in vibrations of the force feedback produced by asphalt.
They are characterized by having a belt transmission system which makes them have a very smooth movement and good sensations. They are also capable of providing more force in some cases. For all this and its price, they become the best option for the regular user of driving games.
Here are the steering wheels with direct drive technology, they are direct transmission systems, the steering wheel shaft is the motor shaft with which absolutely nothing of information or sensations is lost. The forces that they are capable of generating are also very high.
Direct drive steering wheel, direct transmission since the steering wheel shaft is the motor shaft. The forces on these wheels is the highest of all and they are the ones normally used by simracing professionals and real pilots in their simulators.
