Box Three Short BMX Brake Kit

Box Three Short Brake Kit

The Box Three Short Brake Kit is a complete brake package designed for shorter reach applications on BMX bikes. It includes both the brake lever and cantilever arms in a compact configuration, with 85mm brake arms that provide adequate stopping power without the excessive reach of full-size V-brakes. This setup is optimized for bikes with limited clearance or riders who prefer a shorter, more responsive brake feel.

Key Features

• 85mm brake arms – Mini-size arms reduce the distance between brake pads and rim, allowing for quicker engagement and better modulation compared to full-length V-brakes
• Short reach V-point brake lever – Lever geometry is designed to work specifically with the mechanical advantage of mini V-brakes, ensuring proper cable pull and brake feel
• Complete kit – Includes both lever and caliper, eliminating compatibility guesswork when assembling or upgrading your brake system
• Stainless steel brake cable included – Corrosion-resistant cable provides smooth actuation and longer lifespan, especially in wet conditions

Compatibility and Ideal Use Cases

This brake kit fits BMX frames and forks with standard cantilever/V-brake bosses. The mini V-brake design works best on setups where tire clearance is tight or where full-size V-brakes would create excessive pad-to-rim distance. It's suitable for riders running rear brakes on street or park bikes who want reliable stopping power in a compact package. The short reach lever is designed for smaller hands or riders who prefer the lever closer to the bars. Not compatible with U-brake or gyro systems without adapters.
