I believe this is a Thruster System 1. I bought it a while ago and rode it a bit, but I found it again when I went back to my parents' house, so I'm listing it. According to the description on another site: "It has excellent straight-line performance. With just a little effort, it quickly accelerates from the start to top speed. It's suitable for those seeking the feeling of speed found in surfing and snowboarding, or for image training. Recommended decks to pair with it are long types, 40 inches or longer." Instruction manual is not included. Please refer to the photos and save them. - Type: Skateboard Truck - Material: Metal
