Sonar Demon EDM Wheels are inexpensive and stylish, perfect for recreational or session skating. These wheels excel on indoor surfaces that run sticky, such as rinks with coated wood floors and sport courts. The 12-hole speed hub provides rigid support to the tire that is poured using Sonar's indoor performance urethane, giving the Demon EDM Wheels blazingly fast roll that will turn any skater into a speed demon! They are even available in an array of bright colors that make personalization fun and easy.
