We set out to use what we had learned over our years of downhill wheel development to make the ultimate cruiser wheel and the 63mm Rocket Hawg is what we came up with. Featuring a proprietary large offset core and poured in super high rebound 76a or 78a urethane, these wheels are the ultimate upgrade for your cruiser board or city slasher. They have ridiculous roll speed for a wheel of this size and plenty of grip to let you draw tight lines through your commute and get where you need to go in record time. Leave your friends in your dust with a set of Rocket Hawgs today. Warning: The Rocket Hawgs are FAST!
