Strong, aerodynamically designed aluminum shafts and Leki's ergonomic strap system make these bright red racing poles a reliable and functional choice. The straps attach to the grips using Leki's Trigger System: the straps can be slipped onto the hands without the poles swinging along. The system also releases the pole during a fall. The poles are compatible with other Trigger straps and Trigger gloves. - Shaft diameter: 16 mm - Trigger system with Trigger Vario strap - Material: Aluminum - Weight: 254g each
