The Race King has presented itself as a talented newcomer in the best way possible with victories! Irina Kalentieva TopeakErgon took the first prototype to the podium at the 2007 UCI World Cup Championships. The secret of the Race King is a large volume casing mated to a low profile tread pattern that not only spells speed, but also incredible all round traction and control. Paired with our proprietary Black Chili compound, and weighing in at a scant 460g 2.2 SuperSonic, the Race King will impress through an incredibly wide variety of conditions. Choose the 2.0 for the ultimate XC weapon, or the 2.2 when a slightly bigger footprint is needed. Riding a 29er The 29 x 2.2 is bound to be one of the most desirable big wheels in the game.
