are the numbers on the heel and toe pieces supposed to be set to the same number? mine are not the same however i have friends that do have the same numbers should i take my skis to a shop to get them adjusted?
Those numbers indicate how much force it will take for the binding to release. The numbers on the toe piece and heel piece should be the same. I would take them back to the shop, don't adjust bindings yourself.
2bi4 is lightyears ahead of 4bi9, whens the last you saw someone build a house using 4bi9s? -jfletcher
Having a different setting for toe and heel is normal. It could be the way your binding tested out. just because you set it to a certain value, doesnt mean its going to release where its supposed to. Or some people just prefer a higher setting in the heel. I have my toes set and 11.5, and the heel at 13. This is normal.
