The Ride A-4 Snowboard Binding is designed for the rider looking for high-end materials and a high-performance all-mountain binding that won't break the bank. The A-4 uses the same super responsive and lightweight highback Ride is known for. The one-piece ankle strap offers performance and comfort without the extra bulk and weight. The cored nylon highback is designed for responsiveness without the additional weight. The A-Series aluminum chassis provides the reactive flex and power transfer of aluminum with less rigidity than previous designs. The canted footbed aligns your joints with a 2.5 angle while providing more leverage over the tip and tail of your board. If you are on a tight budget, but demand lightweight all mountain performance, this is the binding for you. A-Series Aluminum ChassisThe A-Series Chassis provides the reactive flex and power transfer of aluminum underfoot. The extruded aluminum heel-cup provides ultimate toe heel response. The A-Series Chassis was designed to be less rigid than previous designs allowing the aluminum to flex more under the rider's weight for a much more reactive ride. Because the chassis is 100% aluminum, it's narrower than nylon or plastic chassis allowing the board to flex more freely from tip to tail. Nylon HighbackTraditional highback material that offers a predictable mix of response and comfort. One-Piece Ankle StrapDesigned for comfort and durability, the single material strap provides response and comfort in a utilitarian package that wastes nothing. Minimalist Toe StrapDesigned to offer maximum performance and durability with minimum weight and distraction. Linkage RatchetDesigned to improve ladder durability and eliminate ratchet wag, resulting in a smoother user experience with the same hold you expect. Canted FootbedAn ultralight footbed that uses subtle angles to align the ankles and knees to a more natural and comfortable position. The angle also gives leverage to press the board for huge pop, without affecting your preferred stance width. A-Series Die-Cut Base PadA minimalist EVA pad that sits under the binding to damp out vibrations. Plastic DiscThe plastic disc offers more lateral flex than aluminum for the rider that is focused on comfort and flex over hard-charging performance. table, th, td {border: 1px solid black; border-collapse: collapse;}th {text-align: left;}th {padding-left: 6px;}td {padding-left: 6px;} SIZE Small Medium Large US Men's 4 - 8 6 - 10 10.5+ US Women's 5 - 9 7 - 11 | Ride A-4 Men's Snowboard Bindings Large - Black | The House
