Box One linear brake cable kits are among the most advanced BMX brake cables on the market, starting with custom Concentric housing that includes aramid fiber-wrapped aluminum/steel linear wires for the best combination of strength and low weight. The inner Nano Cable wires are treated with a PTFE coating that reduces friction and boosts braking performance. Our anodized aluminum Kollars™ ferrules further reduce cable drag.
