The ONETEN X series feature an entirely new moving balancer mechanism – the Linear Bearing Oscillator System II (patent pending). This system utilizes multiple ball-bearings to dramatically reduce friction, allowing for startlingly smooth weight transfer. During casting, the impact created by the instantaneous shift of weight to the tail section creates powerful propulsion, allowing for tremendous flight distance. After splashdown, the weight instantly slides to the optimal swimming position and is magnetically secured, allowing for faster startup swimming performance and greater stability.
