The System Skate Barrel Risers are good for boards with a lot of camber or concave, reducing pressure from the baseplates. Barrel Risers are also a great solution for spacing boards with drop through truck configurations. System Barrel Risers are made from Nylon.
Please note: Barrel Risers can add concentrated stress that may not work well on thin or soft boards.
