The Envy Double Clamp Shim is the perfect way to customize your scooter and make it stand out from the crowd. With four colors to choose from - black, blue, red, and oil slick - you can add your own touch of style to your ride. The raw aluminum shim that comes standard with the double clamp works with oversized diameter bars, but with the Envy Double Clamp Shim inserted, it can also work with standard diameter bars. Whether you want to replace the shim that came with your clamp or just add some extra color, the Envy Double Clamp Shim is the perfect accessory for any scooter rider.
