Box One™ 120 TPI Folding Tires were engineered with a minimalist approach to hit lofty goals for weight, traction, rolling resistance, and rebound. At its heart is a super-supple 120TPI casing where we forced in as much rubber displacing nylon as possible. Skin walls are employed to reduce drag and further reduce weight. We flanked the high-density casing with a tightly packed hoop of aramid fibers. Finally, we draped this all with BMX race-specific tread that transitions from a center band with a large contact patch to unidirectional tactile knobbies on the sides. This aggressive combination allows for maximum traction out of the gate, immense adhesion in the corners, and low rolling resistance in the straights. A state-of-the-art mixture of compounds is used in various areas of the apex, wall, bead seat, and center – with higher silica content in the tread to again remove more weight. Note: Not a tubeless tire FEATURES: - 120 TPI High-Density Casing - Aramid Folding Bead - High-Traction Directional Grooves for Starting Gate Grip Point - Low Rolling Resistance Center Strip Chevrons - Countless Ramped Hexagonal Directional Knobbies
