From BMBW: "Versatile performance and all mountain dominance. BMBW’s perfect all terrain combination of an engineered polymer highback and a responsive magnesium fiber drive plate gives you precise freestyle/ freeride performance and control in every riding situation. Lib Tech x BMBW x Transfer enters its fifth year of collaboration with a 30 yr celebration of our legendary rider artist Mike Parillo. Big dark mountains inspire awe and curiosity... what peril and gems lie within!"

Fiberglass panels in the footbed create sophisticated flex patterns and enhance response similar to your snowboard for advanced flex control. Dynamic energy of the specialized composites creates reaction and drive like no other binding can. Asymmetric highbackSlightly cupped and slightly asymmetric shape compensates for the increased rigidity of medium-soft to medium-firm highback material during side-to-side boot motion for a smooth and responsive feel. Highback material: Power polymer – engineered nylon highbackResponsive [7/10] flex formulaEngineered nylon is a slightly stiffer blend than the standard formula, ideal for all-mountain riding with increased response. The Cube – forward lean adjustFastest and easiest forward lean adjuster ever. Dual durometer urethane dampeningFour different angles: 10°, 14°, 18°, 22° Dual band ankle strap (medium) Medium power bandThe medium flex power band has a mid-range surface area for supportive response and a comfortable ride in the broadest range of conditions.
