The A-4 is designed for the rider looking for high-end materials and a high-performance all-mountain binding without breaking the bank. The A-4 uses the same super responsive and lightweight highback we’ve had in the past. 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 degree 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.Specifications:- Collection: Thrash- Response: Mellow- Chassis: Aluminum- Specialty: All Mountain,Park, Groomers- Binding Chassis: A-Series Chassis- Binding Discs: Plastic Disc- Binding Highback: Nylon Blend- Binding Ankle Strap: One-Piece Strap- Binding Toe Strap: Minimalist- Binding Footbed: Canted- Binding Basepad: A-Series Diecut- Binding Ratchet: Linkage Ratchet- Feel: 4/10- Product Type: Snowboard Bindings- Size: LTechnology:A-Series Aluminum Chassis:- The A-Series Chassis provides the reactive flex and power transfer of aluminum underfoot.
