LEKI Ultratrail FX.One The LEKI Ultratrail FX.One are lightweight, fixed-length folding poles built for trail running, mountain running and ultramarathon racing. Designed around LEKI’s trail-specific Shark grip-strap system, it creates a secure connection between hand and pole for efficient power transfer on steep climbs, technical descents and long days over mixed terrain. The carbon shaft construction keeps the pole light and responsive, while the stable folding design gives runners dependable support when the terrain gets steep, loose or technical. Compact, fast to deploy and easy to stow, the Ultratrail FX.One uses a multi-section folding construction with a push-button locking system, making it well suited to race vests, pole quivers and quick transitions during events. The Trail Shark grip, breathable Shark Frame Strap Mesh, grip extension, trail-running basket and trail tip all work together to deliver a secure, efficient and trail-ready setup for racing, training and long mountain efforts. As a fixed-length pole, selecting the correct size at purchase is important for comfort, cadence and climbing efficiency.
