I was bored and threw this out on Facebook and it grew legs so I will ask here. What is the oldest binding you would feel confident in using? Indemnification..inshmenification...IMHO, there are bindings that are no longer indemnified that really are jsut as goo..and safe as any new binding offered today but they are not indemnified and most shops will not toush them for the obvious reasons. Sure, some of these bindings are limited by brake width options, they were designed for skis that were no more than 70mm uderfoot. Granted the brakes might be able to be bent out, they are still limiting. Some of these bindings actually can accommodate wider options and even be updated to be Gripwalk compatible.
An example of modernizing a 25 year old binding...
If you note, that is a 2013 (or so) Blizzard Bonafide. When I did this, the Blizzard rep at the time went balistic. He said "How can you put a 20 year old binding Salomon 997E (11-17) on a brand new ski???" Well, that binding was about as good as any binding offered and the same binding as the $499 Salomon Sth916 Steel that was offered at the time. I would still mount that binding on any ski today.
