Dynafit Fork Superlite 150 z-6

For Dynafit's new Superlite 150 alpine touring binding, the z-6 "U spring"  enables you to change the vertical release DIN values from the standard featured DIN 8 down to DIN 6 for smaller and lighter skiers.  This is in regards to a forward release from the heal.  The lateral release DIN value can be adjusted from 4-13 on this binding.
