If you're buying any of ATK's freeride binding, these are a must. They fill the heel gap you normally get from pin bindings and give you power transfer that's often compromised with tech bindings.
From ATK: When comparing tech bindings with alpine ones we can state that the toe piece is much stiffer and precise on the tech ones. We cannot say the same for the heel parts: on tech bindings, the boot sole cannot be in touch with the ski because every boot has a different sole thickness.
With the new adjustable FREERIDE SPACER we covered and exceeded the gap in between tech and alpine bindings providing an astonishing downhill performance.
2 elastic sliding pads and creates a contact between the boot sole and the ski in order to transfer vertical and torsional loads. The 2 pads grant a proper side release value also when the spacer is loaded during jumps or compressions. The spacer is provided with different washers to customize the spacer height in order to perfectly fit with any boot model sole.
