The Race King has presented itself as a talented newcomer in the best way possible with victories! Irina Kalentieva Topeak/Ergon 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 29'er The 29 x 2.2 is bound to be one of the most desirable big wheels in the game.
