Steep ascents change the rhythm of a trail run. LEKI’s Ultratrail FX.One SL is a folding carbon pole aimed at runners who want to bring their upper body into that effort while keeping equipment compact between climbs.
The manufacturer’s current listing describes a slim, 14mm shaft and a Trail Trigger Shark grip and strap system. The hand strap connects to the grip, giving the runner a direct interface with the pole rather than relying solely on squeezing a conventional handle.
From climbing to carrying
LEKI quotes a 35cm packed length and 139g weight at 120cm for this version. Those measurements relate to a particular pole length; runners should compare the specification for the size they intend to use. The folding construction uses the brand’s Push Button system.
Pack compatibility deserves as much attention as the headline weight. Poles need to be stored securely where they will not catch vegetation, interfere with arm swing or become awkward to reach when the gradient changes.
Choose the setup around the route
A fixed-length running pole calls for careful sizing. Practise deploying and stowing a pair on a short run, then experiment with a climbing rhythm before taking them into a demanding race. Using poles only on event day leaves too much to learn at once.
Check the organiser’s rules too. Some races restrict their use, and permitted storage arrangements can vary. For a retailer, demonstrating the strap release and folding sequence can make the product easier to understand than a discussion focused on weight alone.
