The Leki World Cup Lite is designed for younger/lighter racers. Aluminium construction gives high tensile strength with very low in weight. These poles feature Leki's Trigger S safety system, which saves your wrists from being hurt should your pole get caught up during a fall. Airfoil technology, which involves modifying the shaft into a tear-drop shape for better swing and less air resistance, and a Carbide tip to provide superb grip whatever the condition. Trigger S Safety Release Safety System: Leki's pole safety system works by allowing the strap to be clicked into the handle of your pole so that should your wrist get caught up during a fall, the strap will disconnect automatically, much like a ski binding.
