The K2 Lien AT Snowboard Bindings are for anyone who wants one set of bindings that can do it all. They are on the stiffer side of medium in terms of flex but they still butter really well. You can use them in backcountry, sidecountry, on groomers or in the park and pipe. They are very responsive and have a great board feel. They also cater for a very wide range of boards, so if you just want one pair of bindings that can do everything, the K2 Lien would be a great choice. The Lien uses a Tunable TriPod Chassis with Lock Out Block. This provides power transmission pods that coincide with the three points of contact of the foot and are designed to flex the way your foot is naturally supposed to. 3-degree angled foot beds match your natural leg position and increase your control, while reducing fatigue and allow you to ride longer and stronger. The AT Opti-Highback is the most durable temperature resistant highback shape on the market and offers superb forward lean adjustment. Sender Ankle Straps are padless and responsive and the Perfect Fit 2.0 Toe Straps provide maximum adjustability and fit. Add in the 3D Injected Ankle strap for seamless entry and exit. The binding rounds out with Aluminum fixed –Pivot Ratchets and EZ Feed housings. All these features can be adjusted without tools to keep things simple and fast. Simply put, the K2 Lein is a rock solid, hard-to-pass-up all- mountain package that hits all the key notes.
