At Gear West we have a strong understanding of flex data and how it relates to glide properties of skate skis. Looking at classic skis has been more involved because there are more variables compared to skating, both kick and glide. Over the past year we have spent considerable time looking at bad, good and great classic skis. We look at how the flex pattern changes with load and the static shapes at a given skier body weight. We take the gathered flex data and draw a parallel to how the ski actually performs on the trails.
