For the 2019 season Fimbulvetr announced a new recreational snowshoe model, the Trailr. This snowshoe has composite crampons, which are lighter and have better snow shedding properties. The challenge in this project was to replace a very good metal crampon with a composite one.
The existing 3D formed stainless steel crampons are indestructible and have good grip, but they are also relatively expensive to produce. The chosen material for the new ones is a glass filled poly-amide. It handles low temperatures well and is exceptionally strong and stiff. Switching from metal to polymers opens up great possibilities in reshaping the geometry. In stead of using a formed steel plate with constant thickness, we could now use the geometry almost freely to achieve better functions. “Shape is cheap, Materials Expensive” sums it up pretty well.
