9F Hub Design & Performance Benefits

Developed through extensive research, testing, and real-world track evaluation, the 9F is engineered as a highly advanced 50mm kart hub designed to enhance consistency and performance.

Advanced Heat Management

The innovative 9-hole construction promotes improved airflow and heat evacuation compared to traditional hub designs. When paired with matching 9F wheels, the system helps draw heat away more efficiently, assisting in maintaining more stable tire temperatures and air pressures during demanding race conditions.

Increased Axle Support & Stability

The 9F hub utilizes a compact bolt design that allows for a smaller internal hub diameter and greater contact area with the axle. This enhanced fitment increases axle rigidity while also helping reduce unwanted hub movement under load, contributing to a more secure and consistent setup throughout a race.
