ATK Freeride spacer (AL09) is a micro-adjustable in thickness Spacer that can be installed on the heel part adjustment plate. AL09 is equipped with an elastic slide in contact with the boot that, if properly calibrated, does not modify in any way the values of the lateral release of the binding. AL09 is developed to optimize the transmission of impulses coming from the boot deleting the empty space between the sole of the boot and the top-sheet of the ski, as well as to directly transfer to the ski the vertical jump loads without excessively stressing the boot structure. AL09 has been developed for all those who want to get the most out from their equipment in any skiing condition: the sensibility in the ski-boot transmission reaches never before experienced levels; the imperceptible torsional and vertical movements that are escaped from the accuracy of our ROTATIONAL SYSTEM® are now deleted, in particular during the moments of larger loads on the system.
