The Serpent 401984 low friction belt is designed specifically for the Medius X20 Mini EP chassis to cut internal resistance and improve drive consistency. It helps deliver smoother power from the motor to the wheels while helping protect drivetrain parts from extra loading.
Reduced friction in the belt path allows more consistent torque transfer and steadier throttle response. That smoother operation eases wear on mesh points and bearings, supporting longer service life for related components.
This belt matches the Medius X20 Mini EP layout for a reliable fit and straightforward setup. Proper alignment and moderate tensioning get you back on track without lengthy adjustments.
