The 1:4 gear ratio system is the choice of the leading racers around the world, both in winter and summer starts. Its advantages are minimal effort when working with a trimmer rope and a large range of work. During the race, you can accurately dose the thrust and change the mode of operation of the kite as quickly as possible. The whole system has a long length, when the trimmer is fully tightened, a fairly long free end of the rope remains.
