MAXI 150mmØ and MIDI 110mmØ racing lanes are designed for optimal water dissipation and wave control in high turbidity. MAXI 150 mmØ model used in FINA World Cup, Olympics Games and other top venues. Both MAXI and MIDI use cable SS316 with diameter of 3.1mm and max force of 5kn – allowing higher tension and more effective wave dissipation for the worlds fastest pools. All discs are made from UV stabilized advanced co-polymer thermoplastics.
