So, I recently acquired some old straight directional skis that have some old looking look pivots on them they are orange and yellow.I don't know how old they are. But, their "racing" bindings and the din goes up to 15. Do you guys think they can be mounted and used for park skiing???
If you post a picture so we could see that would be good, but pivots have changed very little in the last 20 years so they probably still work fine. I would get them torque tested if you can to make sure they are still releasing properly though. Also some shops don't like to mount older bindings b/c they aren't covered legally by the manufacturer if the bindings are too old, also you need the jig for the binding unless the shop will mount them freehand.
I haven't used them, but yeah some people do still use them. (Some people still sell them for like $50-75.) I would get them torque tested to be sure they are still releasing properly, just because they are pretty old. Also if you don't feel comfortable using the old style zr toes, the heel pieces on those are the same as the new ones, so you could find a pair of newer style toes for sale on NS or TGR and use them with the heels. (As long as they are around the same DIN range.)
As for the brakes, there's a good tutorial on FKS brake bending in the ski/binding maintenance sticky.
Just so you know I haven't ridden the older style zr toes before, so I don't really know how well they work compared to the newer toe piece's, I just know some people do still use them because you still see them for sale on NS and TGR every now and then.
I found an old set of these and put them on some backyard skis. I never had any problems with them but I just didnt really want to risk it putting them on new skis and having them shit out right away. I would guess they will work. Good luck man!
