The Roll-Line Matrix is the Lightest Frame in the World and represents a turning point in Skating Technology. The new Matrix frame available now from SkatesUS.com and has a reduced height from the skating surface which gives a lower Center of Gravity that guarantees the ultimate in Maneuverability and Stability. The Champagne Color Anodized Roll-Line Matrix is forged from a solid bar of Ergal Aluminum Alloy and Titanium components and is completely CNC machined. Ergal is one of the Strongest and Lightest Aluminum Alloys available and has a lower expansion coefficient and offers the best coiled-spring response. The Roll-Line modified reduced height 07 Trucks with Click Action adjustment system provides optimum, accurate, and consistent Action adjustments using the new 07 series, 13mm base King Pins with Adjustment Click-Nuts and Locking Screws. The Matrix features the strongest and lightest Titanium Alloy Axles in trucks with adjustable Pivot Pins. The design and materials of Roll-Line Skates from SkatesUS.com, provides athletes the proper support of the skating shoe and give the most sensitive control, the greatest and absolute fastest response available from any skate, providing a sense of great stability and action.

Roll-Line Urethane Suspensions provide incredibly quick and fluid energy transmission from the foot through the skate to the skating surface.
The Roll-Line Urethane Suspensions are available in five hardnesses to provide the perfect skate alignment. The Upper (Large) Suspension provides the Stability of the Edge, while the Lower (Small) Suspension creates the Deep Edges, Great Turns and Spins. The Suspensions can be mixed and matched to provide a VERY Custom skate Action. Usually the Upper (Large) Suspension is harder, because it is carrying the weight of the Skater, and provides the edge stability, while the Lower (Small) Suspension is one or (more infrequently) two levels more flexible, providing great edges and changes. Sometimes for FreeStyle Skating, the lower cushion is one level stiffer to support the stability of landing major jumps.
