Saw these on backcountry and it looks and sounds like a screaming good deal to me for brand new bindings. if anyone is in need, I don't really know a lot about them, but I've heard great reviews on them. They don't list the brake size anywhere (that I see), so you may need to get on there chat or something.
Unfortunately, I do not need a pair since I am already set for bindings, but figured I'd share. Sorry if repost.
Check them out.
