Unipro Unigo with water temperature probe

The hub of 35 mm long is considered a "short hub". In karting, The choice of hub length is a fundamental adjustment tool:

• Short hub (35 mm): It offers less contact surface with the axle than models of 75 or 90 mm. This usually allows to have a "freer" behavior of the rear train, Helping the chassis to be free from curve, Ideal on tracks with a lot of grip (adhesion).

The hub of 40 mm long is often considered the "standard" or "versatile" value on adult karts equipped with a 30 mm (x30, axle, Rotax, Kz, ok). Unlike very long (75-90mm) hubs that considerably rigidify the rear, or the very short (35mm) that fully freed the chassis, the 40 mm Offers neutral and healthy behavior, ideal for starting a setting session before refining.

The hub of 85 mm is a "long" adjustment room. In karting, the choice of the hub length is directly related to the leverage exercised on the axle:

• Stability and Grip: With 85 mm, you increase the rigidity of the rear train and removing the load outward. This is the ideal tool for more moving output output or to expand your back path without stacking spacers (which weakens the assembly).

• R2.0 version: This name indicates an evolution of design at CRG (best machining, optimized weight and anodized finish "Gold" for higher resistance to corrosion).
