SPP HG-COMPATIBLE CHROMOLY COGS

HG Precision Interface
Designed specifically for HG freehub bodies (Shimano® compatible), this cog delivers a precise, stable engagement with the cassette body to ensure consistent drivetrain performance under race load.

5mm-Wide Inner Base
The 5mm-wide inner base increases surface contact with the freehub body, reducing micro-movement under sprint torque and improving long-term durability during repeated race efforts.

Chromoly Steel Construction
Manufactured from high-strength Chromoly steel, this cog is built for extended service life and resistance to deformation under aggressive BMX sprint conditions.

Precision CNC-Machined
Each cog is CNC-machined to exact tolerances for accurate HG spline engagement and smooth, consistent power transfer.

ED Black Finish
A durable ED Black coating enhances corrosion resistance while maintaining a clean, professional race appearance.

Laser-Etched Graphics
Permanent laser-etched markings ensure long-lasting identification and branding without wear or fade.

Compatible with both 3/32” and 1/8” chains, allowing flexibility across a wide range of BMX race builds.
