ATK Freeride Spacer For R11, R13, FR15 spacer for ski mountaineering bindings is the top of the range. By comparing the tech and alpine ski bindings, one can appreciate how the toe box of the former is much more precise and rigid than the latter. The same cannot be said for the heels, where the 'tech' sole does not press on the ski like in the alpine binding. The new adjustable FREERIDE SPACER has overcome this gap, guaranteeing more precise skiing than any other model. The basic principle of the spacer is to create contact between the shoe sole and the ski in order to directly transfer vertical and torsional loads. 2 sliding elastic 'pads' ensure that the lateral release value is maintained even when the system is under load (jumps or compressions).The spacer is also equipped with different additional shims to customise the height of the spacer and adapt it to different sole models.   Fits with: RT8 EVO, RT10 EVO, R11 EVO, R13 EVO, FR15 EVO.
