Ok so I've been seeing quite a few questions about the ESTs... How do they work? I don't get how you're supposed to set em up... So I thought I'd make a little thread with some pictures...
So here is "the channel" it is a metal lined trench that is under the top layer of the snowboard.
You can see the space under the top sheet opens up with only a narrow opening at the top.
These are the "T-Bolts" given with the board which you will use to mount the EST bindings to your stick. They are a heavy gauge metal and have grips on the top to prevent sliding once in use.
The shape of the channel allows the "T-Bolts" to slide in under the metal lined top sheet.
Once the end is placed back on the Channel the bolts cannot fall out.
Now lets check out some EST Binders. As you can see all the mounting hardware is located on the outside of the frame consisting of a metal rail on both sides. This leaves the base open and able to be filled with Burton's footbed, supporting foam which allows the board to flex under the binding.
Once you line up the binding with the T-Bolts the bindings will sit flush on the board and are ready to get the other half of the screws put on.
You can see how by not tightening the 2 screws you are allowed to twist the bindings around the 2 points of contact. Giving you a wide variety of free range of positions.
Finally to make adjusting your stance quicker they included a window in the footbed which has a "flap" in the channel to indicate your stance angle and allows you to adjust how wide your stance it.
I know this is very brief but I hope it helps shine some light on it for any of you with questions!
