Unlike other Komperdell-made poles, the tips of the STIX poles are not a separate somewhat flexible plastic part. Instead, the basket retainer is reduced to a ring of plastic around the CF, and the carbide tip is attached directly to the tapered end of the pole.
I was concerned about this type of construction in the Sierra, where it's all too easy to wedge the pole tip between rocks (or wooden bridge planks) and torque the pole. However, the poles survived 220 miles of such abuse on the JMT. Also surprisingly, the exposed CF below the baskets showed less abrasion and wear than I'd expected.
One concerning weakness is that the carbide tips started to separate from the pole. They never were loose enough to pull out, and never separated from the pole by more than a few millimeters, but it was disconcerting: it was doubtful that the bare CF tips would survive 100+ miles of use. I used a few drops of superglue to secure them, but I don't know how much that helped.
