7tm NR Power STI Step-In Ski Bindings - The NR (non releasable) Power STI is the same performance of the Power series, just without the release mechanism on the toe. The 7tm Power offers unrivaled downhill performance in a non-releasable Telemark binding. The greater performance is a result of the removable Power Pin, which moves the pivot point of the binding further under the ball of your foot making it much more active then the first design. The 7tm Power helps Freeheel skiers to more effectively weight their back foot, which is critical for controlling the uphill ski and executing a strong Telemark turn. This is important for aggressive Freeheel skiers and new Telemark skiers alike. The Power Pin is removable to give skiers a choice of "Active" or "Neutral" depending on the snow conditions.
