Mounting marker dukes

AFD; find a piece of 0.5mm thick card or plastic wide enough to cover the AFD and about 10 cm long. Slacken the ADF screw, place card on AFD so that enough protrudes beyond boot sole for you to hold between finger and thumb , place boot in the binding and close heel piece. Turn the AFD screw until the card is jammed between boot and AFD then back off the screw until the card can just slide.

FP; with the boot still in the binding adjust the FP screw until it's flush with the housing. Remove the boot, then put the boot back in the binding and check if the screw is still flush if not readjust.

The fore / aft position of the bindings does affect performance.

Thanks - I get the AFD adjustment bit but didn't quite understand the FP adjustment. Can you break it down a bit (seems to me that the FP screw is always flush with its housing regardless of how far forward or back the rear binding is).

I'll try, as well as adjusting the forward pressure the FP screw is used to adjust the heel piece to the length of the boot. Open the binding and place the boot in it as shown below, then move the heel piece along the track until the heel cup almost touches the boot.



Close the heel piece.



Check if the FP screw (circled in yellow) is flush with housing.



If not adjust it until it is, this is actually better done with the binding open as it puts less strain on the screw and the track. Then put the boot back in the binding and check if the screw is still flush if not readjust.
