The Mountain Twin is designed to offer precision control riding regular or switch on any terrain, from chutes to tree runs to backcountry booters. Jones completely redesigned the shape of the Mountain Twin Split for 2021 by adding a more blunted tip profile, a 3D Contour Base 2.0 and Inner/Outer Traction Tech 3.0 edges. The blunt tips reduce weight, Traction Tech keeps you locked in on firm snow and the 3D Contour Base makes every turn more effortless. For unmatched torsional board lock in ride mode the Mountain Twin Split features the Boltless Bridge and Karakoram Split and Tip + Tail Clips. To complete the redesign we upgraded to our new super fast and durable Sintered 8000 base and added stance options with our new Freestyle/Freeride Stance Pack.
CamRockÂ â€“Â A unique rocker/camber flex pattern defined by evenly balanced tip and tail rocker and camber between the bindings. CamRock improves freestyle finesse by keeping your tips playful while maintaining the power and pop of camber underfoot.
Twin Flex Pattern
Flex Rating â€“ 7/10 (1=Soft,10=Stiff)
Forever FlexÂ â€“Â All Jones boards are broken in using specialized machinery that mimics extreme riding use to help stabilize the flex and rocker profile of a board for it's lifetime.
3D Contour Base 2.0Â â€“Â Moderate 3D-base contours featuring an even balance of 4mm spoon bevel in the nose and 4mm spoon bevel in the tail. Spoon bevel starts at the rocker point.
Progressive SidecutÂ â€“Â At the far ends of the sidecut, the radius is incrementally increased as the edge reaches the contact point. Gradually increasing the sidecut radius towards the contact point delivers smoother turn initiation and exit as the edge tracks in and out of the snow with a less abrupt transition.
Blunt NoseÂ â€“Â "How a board glides in powder, crust, corn or any snow more than an inch deep is dictated by it's front contact point and just past it. Next time you are in soft snow watch how much snow comes over the corner of the nose near the contact point. The billowing snow coming out from behind the tip means you are plowing through it which is obviously slowing you down. By adding a blunt nose you get the float benefits of a much longer nose without the 'snow plow' rounded tip and it's extra swing weight." - Jeremy Jones
FSCâ„¢ Control Split CoreÂ â€“Â Dual-density full premium wood core designed specifically for splitboards. 2:1 paulownia to poplar stringer ratio keeps core light yet ultra damp.
Biax FiberglassÂ â€“Â A dual-direction, dual-layer, stitched fiberglass laminate that provides a fun, forgiving and snappy ride.
Stainless Steel ReinforcementÂ â€“Â Stainless steel plates are embedded into the nose and tail for improved board tip durability.
Recycled ABSÂ â€“Â ABS plastic is one of the necessary evils of snowboard production. Jones improves the sustainability of their snowboards by using only recycled plastic.
Sintered 8000 BaseÂ â€“Â New super durable material made from Ultra High Molecular Weight polyethylene and carbon.
Flip Flop BaseÂ â€“Â Flip-Flop bases improve board sustainability by reducing p-tex waste.
Traction Tech 3.0Â â€“Â Traction Tech 3.0 features three bumps per edge (front binding, board center, back binding). The middle bump is slightly bigger than the outside bumps for better grip.
Inner Edge Traction TechÂ â€“Â Inner edge Traction Tech improves splitboard edge grip on ascent. Three side cut "bumps" on each side of your binding keep you locked in on icy skin tracks no matter which way you are traversing.
Oversized Recycled EdgesÂ â€“Â All Jones boards are made with oversized recycled steel edges for added durability and improved production sustainability.
Eco-Plastic TopsheetÂ â€“Â Bio-plastic topsheet made from Castor beans. This eco-material is ultralight, chip/scratch resistant and water/snow repellent (snow sticks less to topsheet).
Karakoram Ultra ClipsÂ â€“Â Jones Splitboards feature Karakoram K-Clips plus tip and tail hooks. Adjustable tension K-clips increase torsional stiffness and offer a superior connection to simple interlocking clips.
Bolt-Less BridgeÂ â€“Â The Bolt-Less Bridge eliminates split clip attachment hardware from the base of the board by re-profiling the wood core at the clips. The wood core under the clips is thicker providing better torsional stiffness and a more powerful connection at the split clips.
Quick Tension TailÂ â€“Â A built in climbing skin tension system with a pre-cut notch that eliminates the need for a traditional skin tail clip.
Bio ResinÂ â€“Â All Jones boards are now built with bio-based, renewable epoxy instead of petroleum based epoxy. The raw materials used to make Super Sap Bio-Resin are co-products or waste products of other plant-based industrial processes. Producing Super Sap requires 33% less greenhouse gas emissions than conventional epoxy.
Factory TunedÂ â€“Â All Jones snowboards are factory de-tuned at the tip and tail so you can go right from the shop to the mountain.
Wend Natural WaxÂ â€“Â Jones boards are ready to shred straight out of the shop and are factory waxed with WEND natural wax.
Freeride / Freestyle Pack InsertsÂ â€“Â Allows option to center or set back your stance on the sidecut as conditions demand.
