NAXO nX21 Rigidity improvements

 
 
Remove the ski brakes and unlock the heal binding to be able to move it forwards.
Now unscrew the two torx screws (red arrows)and carefully lift the front part of the heal binding then slide
the top part of the heal binding backwards to release it from the lower part.

Now cut for stripes of ptfe tape, Permacel P421 (125 micron PTFE film tape) or similar.
Put these stripes in the bottom of the two slots in the lower part of the heal bindings Red arrows).
In my case I used two layers of this tape to shim my bindings.
Then reassemble the bindings.
(Note the PTFE tape I use is not plumming tape, it is a thicker tape that have adesive on one side)

After reassemble the binding, make sure that it can move on the aluminum bars without
need of any extensive force but at the same time be tight enough not to wobble.
 
Further improvements!
To further improve the stability it is possible to shorten the aluminum bars to make them more
torsion rigid, this of coarse only aplies if you don't need to use the full length of the binding to fit your boot :0)
Anyhow this involves some metalwork and repositioning of the aft ski mount to be done.
Naxo NX21 questions!
