Maximize crank efficiency with the Box One Oversized Cog, engineered for a 5% increase in torque transfer during explosive gate starts. CNC-machined from 4130 chromoly steel, this sprocket component features an ED black finish to resist chain wear. Designed for OS spline hub drivers—like the Onyx Ultra SS—it ensures tires grip the track instantly. Compatible with 3/32” and 1/8” setups, it aligns with stem and handlebar leverage for precision racing. At a weight of just 20g (14T), it’s the ultimate pedal-to-power upgrade for a fork-stabilized, grips-tight elite pro build.
