SPP Supersized™ SS/ OS Chromoly Cogs

Supersized™ OS Spline Interface
The Supersized™ interface increases the engagement surface between the cog and driver, delivering improved torque transfer and reduced micro-movement under full sprint load. The result is a more stable drivetrain connection when power output is at its highest.

Chromoly Steel Construction
Manufactured from high-strength Chromoly steel, this cog is engineered for extended service life and resistance to deformation under repeated race conditions.

Precision CNC-Machined
Each cog is CNC-machined to exact tolerances for a precise fit on SS / OS spline drivers, ensuring consistent engagement and smooth drivetrain performance.

ED Black Finish
A durable ED Black coating improves corrosion resistance while maintaining a clean, race-ready appearance season after season.

Laser-Etched Graphics
Permanent laser-etched markings maintain clear identification and branding without fading or peeling over time.

Chain Compatibility
Designed to work with both 3/32” and 1/8” chains, allowing flexibility across BMX race builds.

Race-Specific Engineering
Developed specifically for BMX sprint loads, where explosive acceleration and repeated torque spikes demand a stronger, more stable drivetrain interface.
