The Roll-Line DERBY Driver RED is for the mid-level Derby Skaters and serious competitors that want the most a skate can deliver, but are not quite ready for the Navigator, Energy Gold or New Matrix. The Roll-Line DERBY Driver RED from DerbySMACK.com provides the best possible performance due to its innovative design and ultra lightweight structure (and is exactly the same frame as the artistic Variant, but with the Roll-Line Click Action Adjustment System). The Roll-Line Driver RED is forged from a solid bar of Aircraft Aluminum Alloy and completely CNC machined. TheRoll-Line Click Action adjustment system provides optimum, accurate, and consistent Action adjustments using the 04 series, 13mm base King Pins with Adjustment Click-Nuts and Locking Screws. The DERBY Driver RED features the strongest Steel Axles available in Anodized RED Trucks with adjustable Pivot Pins. The design and materials of Roll-Line Skates from DerbySMACK.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.
