BOX TWO 70MM BRAKE PADS

Product Overview

The Box Two 70mm Brake Pads are cartridge-style rim brake pad assemblies designed for BMX V-brakes and caliper brakes. Featuring a cartridge pad holder with a pivoting mounting post, these brake shoes accept replaceable 70mm rubber pad inserts for easy maintenance and customization. The pivoting post design simplifies toe-in adjustment for optimal braking performance.

Key Features

• Cartridge pad holder system – Removable rubber pad inserts allow quick replacement of worn pads without replacing the entire brake shoe assembly
• 70mm pad length – Standard length provides adequate braking surface for most BMX rims
• Pivoting mounting post – Post pivots within the brake caliper mounting point, simplifying toe-in adjustment for proper pad-to-rim alignment
• Replaceable pad inserts – Swap worn pads or change colors without replacing metal brake shoe hardware
• Easy toe-in adjustment – Pivoting design allows you to set the front edge of the pad closer to the rim than the rear edge, reducing brake squeal

Technical Specifications

• Pad length: 70mm
• Pad holder type: Cartridge with replaceable inserts
• Mounting post: Pivoting threaded post
• Brake compatibility: V-brakes, caliper brakes, U-brakes (rim brakes with threaded post mounts)
• Replacement pad compatibility: 70mm cartridge-style brake pad inserts

Compatibility and Ideal Use Cases

These brake pad assemblies fit BMX rim brakes including V-brakes, caliper brakes, and U-brakes that accept threaded-post brake pads. The 70mm length is standard for BMX applications and fits most brake calipers. Not compatible with disc brakes or cantilever brake systems that use different pad mounting standards. Verify your brake uses threaded-post pads before ordering.

Best suited for BMX riders using rim brakes who want easy pad replacement and simplified brake adjustment. The cartridge system allows you to replace only the rubber pad inserts when worn, keeping the metal brake shoe hardware in place—this is more economical and convenient than replacing complete brake pad assemblies. The pivoting mounting post simplifies toe-in adjustment (angling the pad so the front edge contacts the rim slightly before the rear edge), which reduces brake squeal and improves modulation. Ideal for riders who perform their own brake maintenance or who want the ability to swap pad colors for aesthetic customization. Important: Brake pads are wear items—inspect regularly and replace pad inserts when the pad material is worn down to approximately 1-2mm thickness. Worn pads reduce braking power and can damage rims. When installing new pad inserts, ensure they are fully seated in the cartridge holder and secured properly. Bed in new pads by performing several moderate stops to transfer pad material to the rim surface before relying on full braking force.
