Any chance they had you on a standard disc/binding and not the re:flex disc/binding?
I only know that the Demo Cartels were 2012/13's. Do they make these in a Non Reflex binding? Is there a version of these 12/13 Cartels without the reflex bindings?
Honestly,.. I don't remember the disk's on the Demo's having these same large teeth on the disk & binding plate for locking in the angles! But my recollection is unreliable on that as I wasn't really paying attention to those kinds of things!
