Ski Ties, flexing.

Snapzzz, it's possible to slide the bindings off the rail, leaving you with an almost flat ski for storage under the bed etc. Many rail systems fix toe and heel piece together on the rail, so you won't lose any adjustments that have been made so far.
I've read of some folks taking 1 set of bindings on their hols and 2 pairs of skis with the same system. It saves weight )
I know that some folks prefer to take off their rail bindings for airline transit and carry them separately.

Bandit. I can see the appeal of that!

I took a look at my bindings and to be honest, with my limited knowledge, i wouldn't dare go anywhere near them with a screw driver!
I took another look today and it became apparent i know nothing really. The front toe piece has a bit that slides left to right (whats that all about?, And i can see a few screws but wouldn't want to turn them.
I have searched online for manuals/instructions for these (atomic xto12) but found nothing, i didn't get any literature with them.
I heard, not sure how true it is, that manufacturers do not supply 'manuals' as they do not want people tinkering with safety devices which would possibly leave them wide open to claims.

Snapzzz, the left/right sliding panel goes under the foot? If it is, then it's a Glide Plate. This helps your boot release from the binding, also known as Anti Friction Plate and on some bindings, works together with the toe pieces opening.

You binding may be in this online manual. It's a pdf.

Yes, I know it says Salomon, but it's definitely a recent Atomic Manual :D

If in doubt, EB's can talk you through taking the binding off the track, quite often it's only 1 single screw holding them in place. I know my last Atomic's were like this!

WOW! Bandit comes through again.

Thanks for the manual, i see i have PLENTY of reading to do.

Your description of the 'glide plate' sounds right. I can see how that would help, I'm not sue i have seen it before though on my rental skis.

From what I can see in the manual, it appears to work like a rental/demo binding. The glide plate is immediately behind the jaws on the toe piece, the adjustment catch is a little rearward of this. Still need a screw driver for the brake. It didn't show the forward pressure adjustment, but that is normally a screw on the back of the heel piece (you shouldn't need to adjust this, but should check it is right whenever you move the binding). Should be very easy to remove and replace.

It's worth figuring this out, as it will allow you to adjust the binding position for the conditions you are skiing. Forward for hard groomed snow, and back for softer or powder snow. If carry a little snowboard tool (includes a screw driver) in your pocket, you can make these anytime.
