Following coach advice: Grind upper part of liner or lift the toe piece ?

post #1 of 5
Thread Starter 

Hi guys,

 

My coach told me I would be better with a more upright position, especially for slalom.

 

Actually, I ski with the RL11 shell, the standard Rossi WC gold R2005 boot(ZB/ZB).

 

I know they have a greater forward lean than more "modern" shells.

 

I figured I had two options: Grind the upper back (plastic) part of the liner, or use a lifter to move the toe part of the binding up a little on my slalom skis.

 

What's your thoughts on this ?

Do NOT modify your shell.  It is the rare rare rare rare (rare) person who truly requires less forward lean.  An awful lot of WC athletes ran slalom on that chassis without screwing around with the forward lean angle.

 

1)  Have someone compentent look at your foot/ankle range of motion.  Also have your calf circumference measured at the level of the cuff. 

 

2)  What is the delta angle on your binding?

 

3)  Consider experimenting with a toe lift.

 

4)  Consider removing the forward lean shim on the liner and test.

 

5)  Make sure it isn't simply a technical/motor skills problem rather than an equipment issue.

 

Hope that helps!

grinding rear spine will allow you to stand more upright, and open your ankle angle more

 

 

lifting the toe (externally on the boot) will keep your ankle at the same angle, but move your mass back a bit (and you might just counter that by flexing more at the waist)

 

Both are great options, but can solve different problems.  Best to ask the coach what he sees and what exactly he wants.

Hi all,

 

I have the Rossi 155 binding , don't know the delta angle.

 

I never used the rear shims, I already find I have too much forward angle.

 

I guess I need self-made shims (maybe Rossi has different ready made models ?), and probably a little longer screws to lift the toe a little...

 

 

 

....Is 1 mm too much to start with ?...

 

Since I haven't been skiing the past....14 years or so, on short term I will still concentrate on developping new skills  (my coach said I had great technique....if I was in 1982 and used 205 cm skis...)

1mm is possibly not enough but with 1 mm lift you can probably use same screws.  With the binding you are using I would start at about 3-5mm.  At least you will feel the diff.
