BOX ONE SINGLE SPEED ALUMINUM COGS

Box One Single-Speed Aluminum Cog

The Box One Single-Speed Aluminum Cog is engineered for BMX racers seeking the lightest possible drivetrain setup without sacrificing engagement precision or durability. Precision CNC machined from premium 7075-T6 aluminum, these cogs deliver exceptional weight savings while maintaining excellent stiffness and drivetrain efficiency.

Designed to fit Shimano™ HG-compatible cassette hubs, each cog features a widened 5mm inner base to create a more stable and solid interface with the freehub body, helping improve load distribution and reduce wear under heavy sprint efforts.

Finished with a clean anodized coating and laser-etched graphics, the Box One aluminum cog combines lightweight race performance with premium aesthetics.
