Designed to replace the existing drive side hardware on Primo's FreeMix hub. The alloy cone nut is specifically machined to allow the plastic guard to snap right on with no need to spread your frame. Replacement guards are also available separately. Recommended for use with 9th drivers or smaller (may still get some chain rub with half link chains, depending on hub spacing). Can be used for RHD and LHD.
