Underbite Outline: UnderBite edges re-distribute a rider’s weight in such a way that it enhances turning ease and edge hold. Creating divots inward at the binding area reduces and disrupts the surface area of the edge that has contact with the snow while the board is turning. This increases the edge pressure by distributing your weight/energy in the areas where you need it - from the binding out, and through the center of the board where the carving arc is taking place. This segmentation of the sidecut into 3 key zones focuses your body weight onto areas that initiate, hold and release turns.
Full Poplar Core: Yes Snowboard's baseline core for tip to tail wood-core snowboard construction. Strikes a predictable balance between durability, consistent flex and light weight.
Extruded Base Materials: Just like it says. This material is formed by extrusion. It’s softer than Yes's other two bases, which isn’t necessarily a bad thing. At the speeds many folks ride, this material is actually quicker (gets up to speed faster) than sintered when waxed correctly. You may have your own proof of this when you’re smoking by someone with a dried out “high-end” base. It also retains wax better because it’s more porous and is easy to fix with a P-Tex stick if you get scratches in it.
