The spike is a dedicated mud tire. Its square profile and extra tall knobs are designed for maximum mud traction. Pyramid shaped knobs with base reinforcement let us run a smaller knob top that won't fold over under load. When wet or muddy conditions are present this tire is a must. The new 2 ply foldable tire will save you over 195 grams per tire while keeping you on route with the
S 50 Sticky Rubber Compound.
