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.
