🏔 Why This Matters

The 22 Designs HammerHead is one of the most influential 75mm Telemark bindings ever produced. Small components like the heel key are essential—without it, the heel piece assembly cannot function correctly, even if all major parts are present.

Because these pieces are no longer produced, sourcing original heel keys is increasingly difficult. Keeping them in circulation helps complete heel assemblies and keeps classic HammerHead setups skiing as intended.
