OAC EA - Easy to adjust, easy to assemble EA IN DETAIL We have a long experience in designing universal bindings and we have focused our latest innovations on the EA binding. With easy adjustability, simple assembly and high durability in mind, we created something which works perfectly in tune with our skin based ski range. The EA binding works with a wide range of flexible sole boots in all weather conditions. We have chosen the best materials we know to work in even the harshest environments. A thick flexplate with hinge mechanism gives good ski feeling and offers excellent lateral stability. EA offers a wide size range for most adult boot sizes. The EA Binding is collapsible and simple to reassemble. The base unit features a new spring mechanism, which doubles as an adjustment lever. Size adjustment can carried out with gloved hands as well.
