The CrossMark II improves on the speed of its predecessor while improving grip in intermediate conditions. The legendary center ridge still flies on hardpack, and the updated tread pattern provides better braking and cornering over a wide range of trail conditions. A great choice if you want to go fast everywhere. DUAL Compound - Two compounds used within the tread of select tires to offer lower rolling resistance and increased cornering grip. Folding - Kevlar beaded tyre, lighter weight and more supple TR Tubeless Ready - Tubeless tyres provide the rider with many benefits: the ability to run lower air pressures, which improves traction; lower rolling resistance when compared to a tube-type tyre; and less chance of flatting since there is no tube. Maxxis Tubeless Ready (TR) tyres provide the benefits of a UST tubeless tyre without the weight penalty. The square bead profile of our TR tyres is designed to work with the broad range of tubeless rims available on the market today. Our TR tyres use a special construction which allows the use of liquid sealants to make them airtight and to help prevent punctures. If needed, Maxxis TR tyres can also be used with an inner tube. EXO - An extremely cut-resistant and abrasion-resistant material added to the sidewalls of select mountain tyres. This densely woven material is also lightweight and highly flexible, ensuring that the performance of the tyre remains unaffected.
