Box One Conversion Rear Axle

Box One Conversion Rear Axle

Product Overview

The Box One conversion rear axle is a premium performance component engineered for oversized frame dropouts and versatile drivetrain setups. The aerospace-grade aluminum construction with convertible 10mm or 15mm design enables adaptation of standard 20mm hubs to fit different frame specifications while maintaining exceptional stiffness and precision.

Key Features

• Oversized Technology™ – Engineered specifically for oversized frame dropout compatibility; delivers superior stiffness and precision compared to standard axle systems
• 7075-T6 aerospace-grade aluminum – Premium material provides maximum strength-to-weight ratio; aerospace specifications ensure durability under extreme racing stress
• CNC lathed precision construction – Computer-controlled manufacturing delivers exact tolerances and consistent performance across all units; precision engineering eliminates play or flex
• Anodized finish with laser-etched graphics – Professional finish resists corrosion and wear; laser-etched branding provides durability without paint degradation
• Convertible design – Adapt standard 20mm hubs to fit 10mm or 15mm frame dropouts; eliminates need for multiple hub specifications across different frames
• Adjustable length – 125mm to 165mm adjustability accommodates various frame geometries and rear dropout spacing without limiting options
• Stainless steel hardware – Corrosion-resistant fasteners maintain function and appearance in wet conditions
• Ultralight construction – 86-123g weight depending on specification keeps rotational mass minimal while maintaining rigidity
• Direct manufacturer shipping – Shipped directly from Box One; may require additional lead time but ensures product authenticity and quality

Compatibility and Ideal Use Cases

Compatible exclusively with frames featuring oversized dropout geometry; standard frame dropouts will not accept oversized axles. Ideal for riders with oversized frame systems seeking premium performance and lightweight construction. Suitable for high-level BMX racing where rigidity and precision matter. The convertible design works with standard 20mm hubs, enabling hub versatility across different frame specifications without purchasing multiple hubs. Works with any standard BMX chain and sprocket configuration. Recommended for competitive racers, riders with oversized frame systems, or anyone prioritizing aerospace-grade materials, precision construction, and lightweight performance at premium specification levels. Note: Ships directly from manufacturer; may require additional lead time and ships separately from other brand orders.
