Slipstream 100mm Reduction Wave Racing Lanes are specifically designed to reduce the wave motion between lanes, reducing turbulence for the swimmer. They are made with tough and durable UV resistant polypropylene 100 mm disks and 4 mm stainless steel cable with a stainless steel snap hook at one end. They can be secured in place with either of our slipstream lane tensioners. The 100 mm racing lanes are available in 25 m, 50 m or custom lengths and in a selection of colours. The lane discs have internal flotation which eliminates the EVA discs placed at intervals on the lane. The internal disc flotation allows for the correct lane flotation level which offers the best wave reduction between the lanes.
