Continental's Race King 29 inch Tire is built tough for cross country rippers who demand power and excellent, all terrain traction. Continental uses its proprietary Black Chili compound for the Race King, which not only improves grip, but also makes the tire stronger and lighter. Compared to Continental's earlier generation tire compound, Black Chili tires provide around 20% less rolling resistance and 30% more grip, all while managing to improve tread life by 5%. The Race King's low profile tread pattern delivers excellent power transfer and superb handling. To accomplish this, Continental uses a rolled shoulder profile, transitional knobs, and a diamond head arrow center tread pattern. Along the outer edge, the pattern uses a ramped leading edge and a block tread. The blocks enhance traction while the ramps ensure a quick rolling tire. The Race King is also built with Continental's ProTection technology, which provides wall to wall protection against punctures.
