Description Description ABS plus buckles OPB system for great kicking efficiency Channel thrust technology Facts Code: 410008 Material: Thermoplastic rubber-Technopolymers Blade: 37cm (size R) Weight: 0.7kg (size R) Blade Thrust Area: 700cm² (size R) Technologies OPB – Optimized Pivoting Blade Allows the blade to maintain an optimal angle throughout the kicking cycle, whereas traditional fins achieve this only during a small portion of the cycle. OPB produces a constant thrust, which minimizes fatigue and produces fluid movement through the water. Channel Thrust Soft longitudinal inserts allow a controlled deformation of the fin blade while kicking. This channel shape moves a greater amount of water resulting in more thrust for the same effort.
