The 50mm x 100 - 8A HQ BirelART Freeline rear wheel hub is an essential part to ensure excellent stability and optimal power transfer . Designed in high-strength and anodized aluminum , it offers durability, reliability and performance on the track. An official BirelART product , ideal for competitors and enthusiasts.

Discover the high-end rear wheel hub signed BirelartDesigned for demanding drivers looking to maximize their driving experience and refine the behavior of their chassis. Made in Magnesium HQ (high quality)This hub with a length of 100 mm for 50 mm shaft is an essential technical part to optimize the rigidity of the rear gear and ensure perfect stability during acceleration phases and strong curve support.

The use of the HQ magnesium makes it possible to drastically reduce the masses not suspended from an aluminum model, providing a better thermal dissipation of the tires and a much more progressive behavior of the kart on the tracks at high level of GRIP. Its great features lies in its system to Double clamping by reinforced flanges. This high-end mechanical device distributes the pressure force in a perfectly uniform manner on the 50 mm shaft, eliminating any risk of sliding of the hub along the axis, while avoiding marking or deforming the axle tube under the effort.
