Erik's Signature Aztek wheels feature an all new full-core design, and his signature graphic and color. Full core wheels are popular for their lightweight, and Aztek is known for their reliable and fast urethane. 30mm wide wheels are beneficial as they provide a wider platform for manuals, and riding fakie (going backwards). The wider wheel also offers a larger amount of clearance for the sides of your deck. That means you don't have to get as pitted if you're carving a bowl, and you'll wash out less when you're going backwards! If wider wheels have interested you, but the weight held you back from pulling the trigger on a pair, then these are for you!
