The excellent Freeride Spacer Kit is a recommended optional extra for the Evo model bindings.
The fully adjustable Freeride Spacer supports the underside of the heel of the boot when it's clicked in the heel binding. It provides a level of precision and power transmission matching that of a high end alpine binding. The spacer provides an incredible torsional stiffness to the boot and transfers the vertical pressure of big jumps and cliffs directly on the ski whilst still keeping the lateral elasticity to provide a proper lateral release.
Weight = 29g per ski.
