Binding Forward Pressure - Railflex

post #1 of 13
Thread Starter 
What is forward pressure when setting a binding?

How does one tell if they have set the forward toe pressure correctly?

I have a pair of fischer rx8's (not the fires, but last years model). On these bindings, how can one tell one has set up the binding correctly for the respective boot size.

I mounted the binding (easy as pie, my boot sole lenth was between two of the selected numbers for the binding, so had to push the rear binding minimally forward (moved forward to get the precise distance).

How do I tell that I have the forward toe pressure right? Is there an indicator bar view, and if so where?

I have mounted the Fischer FX12 Railflex II bindings on my new RX8s. I couldn't believe how easy this was. I thought my Marker Motions on my Volks were easy, the Railflex, my kids could mount.


The question. The forward pressure adjustment is not the conventional flush screw; rather, there is a sliding tab adjustment at the rear of the binding that allows for a further micro adjustment for boot length. I notice that it slides when you mount the boot.

The tab to slide the heel piece forward and back has 6 lines on it. The metal below that on the heel has 3 lines. Is the goal when the boot is mounted to get the 6 lines to all fall within the 3 line boundary?


Thanks,

There is some kind of gauge for adjusting the forward pressure on the heel piece. It should move when you step in with your boot.
I have no idea what you mean when you say forward toe pressure.?

There is a tab on the heel (you lifted it up to slide the heel forward), that tab has scribed lines on it. When you put your boot in the binding the heel should slide backwards slightly, the back edge of the binding housing should partially cover the scribed lines on the tab.

Just like the previous couple of posts have indicated. I am no expert and like you I mounted the same bindings as well as 2 more for my kids tyrolia rfl70. I do have a tecnician's manual for your bindings and that is what I refferenced. When you are adjusting the length of the railflex you match the numbers as close as possible to your boot sole length. I think that for some boots you can't be spot on as some have length let's say 307mm and numbers are in 5mm increments on the rail. ASs far as the forward pressure, you are suppose to fall within the certain range on the tab on the heel peace when boot is locked in place. If you want I could possible email you the copy of this manual. It is in a pdf format. Now all of this being said, I know nothing about the subject so don't hold me to it.

I'll pm you with my email address.

Hi,

I'm after the same info. The question was asked in the original post

"The tab to slide the heel piece forward and back has 6 lines on it. The metal below that on the heel has 3 lines. Is the goal when the boot is mounted to get the 6 lines to all fall within the 3 line boundary?"

What is the answer to the above question please? I have read the manual, but I found it a bit vague working out exactly what bits they are actually talking about. Spielerman described it beautifully!

Cheers

You want the back edge of the binding plastic, on each side of the tab, to fall in the range of the lines on the tab when the boot is clicked in. There may even be an arrow molded into the edge to emphasize this. And to make it clear, the tab and the metal track are fixed when locked down. The binding heel piece slides relative to them.

I'm no expert, but it sounds like you are descibing the "Railflex Lite", I have the Railflex II System.

In the manual. It's easy. "Quote" Place the boot in the binding and close it. The indicating pointer should rest within the scibed area.

Thats is very straight foward. My questions are.

Is The "indicating pointer" the tab with the 6 lines on it that you lever up to adjust?
Is the "Scribed" area the metal below that with the 3 lines?
Or visa versa?

Thanks

I'll try to say what others have said differently.

The tab you lever up to adjust has 6 lines on it.
The back of the plastic area above the tab with 6 lines has an arrow pointing down. With no boot in the binding this plastic arrow points in front of the 6 lines. As you insert the boot the plastic arrow will move back to point somewhere in the zone defined by the 6 lines when correctly adjusted. If you don't see the arrow just use the back of the plastic as the pointer.

Everything below the 6 line tab is to be ignored.

I'm talking about RF II. As Steve noted, the only lines that matter are the ones on the tab. The tab moves relative to the binding edge which is the marker. The tab does not move relative to the track with your three lines, so they are not meaningful in setting forward pressure. Just forget about those three lines, they are not relevant (along with any other lines on the ski or binding!).

Thanks heaps, it all makes sense now. That bloody plate with the 3 lines was confusing me.
