George L.wrote a review of Dynafit Se7en Summits Carbon-Titanal Backcountry Ski Pole on January 3, 2013
I bought these poles for my wife at the beginning of last winter. On the positive, the poles have a super light swing weight, nice grips, and a good locking mechanism. On the down side the carbon fiber shaft snapped after 30~40 backcountry days. The poles were never used resort skiing and were not abused in anyway. Not sure why it snapped. Maybe due to the twisting / cross load associated with spinning dynafit bindings? The carbon shafts are not round (they have a flat side) so I wonder if a stress builds up along the flat edge.
