Why We Like It

  • 170 g per binding with 20 mm of length adjustment included.
  • The single-piece 7075 aluminum construction keeps the binding stiff and simple.
  • A 41 mm climbing wedge and a flat mode cover most skin tracks.
  • Fixed release at 8 suits racers and long objectives where weight matters most.

Best Uses

  • Ski mountaineering
  • Skimo racing and training
  • Long backcountry objectives
  • Spring missions

Mounting and Setup Advice

Release is fixed at 8 in both directions; a shop should confirm that suits your weight, height, age, boot sole length and skier type before you mount.

There is no brake, so use a leash. The included plate gives 20 mm of length adjustment, and the binding needs boots with certified tech inserts.
