Construction & Design

The rotor is crafted from high-grade G3000/G11H18 iron castings, known for their excellent mechanical properties and resistance to wear and thermal stress. This premium material choice ensures the rotor maintains structural integrity and consistent performance even under demanding braking scenarios. The GeoSPEC coating is a proprietary finish that offers superior corrosion protection, significantly extending the rotor’s service life by preventing rust and surface degradation common in conventional painted or zinc-coated rotors.

Additionally, the rotor’s non-directional surface finish is engineered to facilitate quicker bedding-in with brake pads, resulting in improved initial braking response and smoother stops. The precision machining and mill-balancing process eliminate runout and vibration, contributing to a quieter and more comfortable ride.
