Street Invaders are 84a hardness and great for indoor and outdoor use. These wheels feature a semi-round profile for better balance and grip.

Street invaders are available in elliptical or round profiles. Elliptical profile wheels (also called bullet profile wheels) are sharper in shape and create slightly less friction, making them better for speed. Round profile wheels have more contact with the ground for improved grip and comfort.
