Graphite is tried and true but NyOil has its advantages and disadvantages. Nyoil will stay on your axles throughout the races, whereas loose powdered graphite will blow off your axles each time it runs down the track. Our graphite-coated axles are designed to keep the graphite on your axles throughout all your heats, and track tests proved they are faster than NyOil coated axles. Nyoil MUST be used sparingly, only one or two drops! DO NOT mix graphite and NyOil.
