Thank you for viewing. - Brand: SINANO - Product Name: Trail Running Pole 13.6 NEO - Material: Aluminum - Color: Blue Excerpt from the manufacturer's catalog: Size (cm) Height Guide (cm) Weight/pole (approx.) Maximum Load 120cm 173-178cm Approx. 161g 24.8kgf The following is quoted from the manufacturer's website: "SINANO's commitment to aluminum alloy for trail running is the result of years of research and experience with various materials. Instead of 'carbon that becomes unusable if broken,' 'aluminum that can be used as support to the end even if bent' increases the success rate of grueling long-distance races. The shaft of the Trail Running Pole 13.6NEO uses a specially designed ultra-super duralumin shaft. This aluminum alloy, also used in aircraft, achieves a high level of both the rigidity to withstand harsh races and the required light weight. The design of the aluminum shaft, which relieves stress through 'flexing' when subjected to tension or impact, is why it is chosen by top runners. Shaft breakage can be caused by overload or scratches. The difference between carbon and aluminum is also evident in the damage situation. Carbon breaks and snaps, while aluminum has the characteristic of bending before breaking. Troubles are inevitable in long-distance races. The big advantage of aluminum trail running poles is that they can be used until the finish line even if they bend.
