Tech Specs

The Roll-Line Killer Steel Professional Roller Derby Skate Frames are an unprecedented collaboration between top athletes, technical specialists from around the world, and sports Biomechanists from the University at Bologna to produce this Revolutionary NEW Design in a Skate with two (2) different Angled Truck Systems on each Skate.  The Roll-Line Killer Steel Professional DUAL ACTION Roller Derby Skate Frame is a highly technical Skate Frame, with Cross Braced Box Truss engineering for excellent Structural rigidity and is the Lightest and Strongest Skate Frame in the World. The Front Trucks are the Standard (approximate 20 degree) Action for that incredible sensitivity and control for easy edging, that the Matrix is known for.  The Rear Trucks are at a special (approximate) 12 degree angle that allows the truck to Rock but inhibits the Rotational movement.  This translates to incredible stability for those tough hits, along with super control in the very fast action.  This Skate is specifically designed for high level Roller Derby Skaters and represents a revolutionary turning point in Skate and Skating Technology.

Exploded-Frame-Skates-US-2-300x216 KILLER (Steel) Skate Frame (Special Order only)The Roll-Line Killer Steel Professional DUAL ACTION Roller Derby Skate Frames are available now from and has a reduced height from the skating surface which gives a lower Center of Gravity that guarantees the ultimate in Maneuverability and absolute incredible Stability, even at high speeds. There are two colors available Silver (like an anodized surface) and Black anodized.  The Roll-Line Killer Steel Professional DUAL ACTION Roller Derby Skate Frame is forged from a solid bar of Ergal Aluminum Alloy 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.  This major innovation is what makes the Roll-Line Killer a great choice for Roller Derby and also for high speed Rhythm Skating.  The Roll-Line Killer features the strongest heat treated and annealled Steel Alloy Axles (7mm Only) in the trucks available.  The design and materials of Roll-Line Skates from, provides all 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.

For the Roll-Line Killer, due to the Lower Center of Gravity and shorter King Pin, requires the use of Suspensions that are 1 level hardness, more flexible than used on most other Roll-Line Skates.  The Clear Yellow, EXTRA Hard Suspensions ARE NOT Available.  Most Skaters use the three more flexible Suspensions as needed.
