The Roll-Line Energy Steel is a very popular plate for professional skaters, offering the best possible performance levels due to its ultra-lightweight construction! Featuring 7mm axles made from the strongest steel available and adjustable pivot pins, and is otherwise the same plate as the Roll-Line Energy Titanium. Provides the most sensitive control, the greatest and absolute fastest response available from any plate! The Roll-Line Energy Steel is forged from a solid bar of Ergal Aluminum Alloy and 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. Energy Steel uses the Roll-Line click action adjustment system with 04 series, 13mm base king pins, adjustment click-nuts and locking screws. Choose silver or blue trucks, with standard, natural rubber or urethane suspensions, in your choice of hardness. Choose from three available toe stops. Plates are sized according to wheelbase measurement (from centre of front axle to centre of rear axle) from 120mm to 210mm. If you aren't sure, please ask for advice on selecting the right size for your needs!
