Engineered for speed, toughness and grip in dry to damp conditions, the Continental Dubnital mountain bike tire is the go-to choice for cross-country and down-country riders. It delivers maximum efficiency while maintaining stability during quick turns and fast descents, whether you're tackling rocky, hardpack terrain or moderately damp soils. Our Grip compound and tough Trail casing deliver the perfect balance of high traction and low rolling resistance, while the E25 eBike rating ensures added puncture protection and enhanced wear resistance. The redesigned center tread features siped and increased studs for ideal traction while maintaining smooth rolling, with reinforced transition and shoulder studs for confident cornering and superb grip in off-camber sections. Tubeless-ready and hookless compatible, it pairs seamlessly with our Conti Revo Sealant for fewer flats, greater comfort and the ability to run lower pressures. Plus, its foldable design fits neatly into your cycling backpack alongside essential accessories like your repair kit multitool, tire levers, spare tubes and CO2 cartridges. Whether you're out on the trail or racing to the finish line, the Dubnital is always up for the challenge.
