the ZRR 18 is an 18 Din binding, and also has a full 360* pivot heel. It also features 10mm lateral travel vs the 1-14 spacers 7mm. Also the 18 Din is Race Stock, so no high tech graphics, just plain old fasioned Look Bindings. They look like they are from 1970, with more of a square style of appearance. Last year's binding has not changed simply because it is so good.
It is the binding I have ridden for years and it is by far the best binding for advanced riders in NewSchool Skiing. Rossi also makes this same model, and I believe they call it the Scratch 180, or the 180 Pro Race. Most of the time you have to special order them.
