Sprocket/Rotor Hub

The Sprocket/Rotor Hub from Triple X Race Components is a precision-engineered brake and sprocket assembly designed for micro and mini racing applications where reliability and lightweight performance are non-negotiable. Built for kart builders, race teams, and enthusiasts who demand consistent power transfer and brake response, this hub serves as the critical interface between your drivetrain and stopping system. The 1-3/4 inch axle diameter accommodates standard racing specifications, while the 5/16 inch mounting holes ensure secure attachment to your frame and suspension components.

Manufactured from aluminum and finished in black powder coat, the Sprocket/Rotor Hub delivers weight savings critical to acceleration and deceleration performance in competitive racing environments. The aluminum construction provides excellent heat dissipation during extended brake application cycles, while the powder coat finish resists corrosion and provides long-term durability against moisture and salt exposure common in both indoor and outdoor racing venues. At just 0.61 pounds, this hub minimizes unsprung mass—a key factor in chassis responsiveness and tire contact consistency on tight racing circuits.

Triple X Micro/Mini kart builders and sprint racing competitors rely on this hub for its proven fitment compatibility and straightforward installation. The standardized 1-3/4 inch axle dimension integrates seamlessly with most modern micro and mini chassis platforms, while the five-hole mounting pattern accommodates both brake disc and sprocket assemblies without modification. Whether you're running a local club race or preparing for regional competition, this hub delivers the precision engineering and durability expected from a trusted motorsports component manufacturer.
