The Roll Line Blaster Plates are machined CNC milled out of a solid block of aluminum for an extremely consistent and reliable response. The oversized kingpins are set at 18 degrees in the front and 16 degrees in the back to give you a little added agility when entering your turns and transitions while staying very stable during your stride. Locking kingpin set screws allow you to lock in your tension adjustments on the oversized urethane cushions. Please note! This plate uses Metric threaded toe stops and includes a set of metric Ambra Round Toe Stops.
