Optimized for aggressive cross country or trail riding, the Advanced Trail Casing (ATC) is lighter and more supple than either of Kenda's gravity solutions. Using sheets of Kenda's SCT fabric across the tire sidewalls and a sub-tread belt of K-Armor under the tread blocks. The K-Armor fabric has a tighter weave, resulting in the use of less rubber during the construction process, yielding a lighter tire and a casing that is supple enough to allow the knobs to flex and form under load, yet still protects from pinch flats, punctures and cuts.
