Please note this is an order in product at the moment and could take up to 2 weeks to get to you THE KILLER IS A HIGHLY TECHNICAL PLATE WITH A CROSS BRACE STRUCTURE AND EXCELLENT STRUCTURAL RIGIDITY. ROLL LINE HAVE FUSION OF THE CHARACTERISTICS OF THE BEST ARTISTIC PLATES TO MERGE THE BEST PERFORMANCES IN ONE PRODUCT. The KILLER 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, has a lower expansion coefficient and offers the best coiled-spring response. The Titanium version features 7mm axles. There are two colors available: silver anodized and black anodized. The expected weight difference between a titanium 7mm axle and a standard steel 8mm axle is 110g, or around 10% of the total weight of your fully assembled plates. (basically, this plate is 110g lighter because of the 7mm titanium axles than the regular killer plate) Differently angled trucks: Front truck 18 degrees Back truck 15 degrees The greater inclination of the front axle allows the skater to enter curves more easily and with less pressure, the lower inclination of the back axle improves stability and centering when turning. The KILLER are the only roller derby plates featuring a very particular characteristic: the toe stop housings are differentiated between right and left to better adapt to the skating action.
