MBS' medium (orange) polyurethane formula is ideal for riders craving more stability than the soft white Shock Blocks that come stock with the Matrix III can offer. Oranges in the inside position are great for average-size riders riding without bindings. Oranges in the outside position are perfect for pushing the limits of speed and stability when riding with bindings.
Our soft (white) polyurethane formula is our softest yet. Mount them in the inside position for the tightest turns imaginable - ideal for lightweight riders or maximum carveability when riding without bindings. In the outside position they offer a great all-around feel - the ideal balance of carveability and stability for average size riders riding with bindings.
We formulated MBS' hard (red) polyurethane blend with one thing in mind - stability. Red Shock Blocks mounted in the inside position are great for very heavy riders riding without bindings. Reds in the outside position are for riding with bindings at extremely high speeds (think straight!).
Only for Matrix III truck system. Not compatible with older style Matrix trucks.
