SPP SS COGS
DESCRIPTION
The SPP Supersized™ Chromoly Cog is heat treated and engineered for maximum torque transfer and drivetrain stability under elite BMX sprint loads. Designed specifically for SS/OS spline drivers, the Supersized™ interface delivers a wider, more stable engagement platform that reduces micro-movement between the cog and driver during full-gate efforts. CNC-machined from high-strength Chromoly steel and finished in durable ED Black with laser-etched graphics, this cog is built for long service life and race-ready precision. When acceleration matters, interface strength matters.
FEATURES
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 heat treated 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.
