I have a pair of look PX bindings mounted on a fat pair of powder boards (120mm underfoot) Guy at the shop couldn't bend the brakes, (started at 78mm).
He told me to try to find a pair online, and make sure they are the "old style" brakes. The "old style" that he is referring to is the shape of the metal clip underneath the plastic part that connects the brake to the rest of the binding.
Apparently they changed it somewhere along the way. Any help would be greatly appreciated !
my first thread, so apologies in advance if I messed anything up
