Riders whose home terrain is often loose and muddy have reason to rejoice the Continental Mountain King 27. 5 was designed with you in mind. Large, widely spaced lugs bite into soft dirt and shed mud quickly. The Mountain King also comes with Continental's Protection casing, so you'll get fewer flats while you're running this tough as nails tire. The Mountain King is made with Continental's revolutionary Black Chili compound, which decreases rolling resistance by 26%. Black Chili also increases the tire's durability by 5% without adding any unnecessary weight.
