The Ground Control tire is such a great trail tire, we have adapted it for all sizes and ages. This tried-and-true design features CAD-engineered knob shapes, which strengthen the knob structure for optimal braking and traction, but it keeps the knob surfaces adaptable for the best possible grip on mountain trails. - Casing: 26 TPI - Bead: Wire - Compound: 60a - 20x2.35", 25~50 - 24x2.35", 25~50

When your ride varies from skate parks to city streets, and usually ends with a session at the trails, the Rhythm Lite is the obvious tire of choice. A fast-rolling center section keeps things moving, while slightly larger and deeper shoulder knobs provide enhanced traction in the dirt.
