The Intruder is one of the newest tires in the line. An adverse conditions tire, the Intruder is at its best when conditions are too wet or sandy for a hard terrain tire, but not enough for a spike tire. Slightly taller knob heights provide amazing soft soil penetration. In intermediate situations with mud, grass, rocks and roots there is no equal. The new 2 ply foldable tire will save you over 300 grams per tire (2.50 Size) while keeping you on route with the S 50 Sticky Rubber Compound.
