A novel peg apparatus adapted for mounting onto various axles types (e.g. bicycle wheel, conveyor systems, internal machine parts). The device provides either fixed or roller action as preferred by the user. The roller action affords enhanced operating performance and safety in terms of end user satisfaction in each area of potential use. The peg includes an outer sheath made of one of a number of an industrial grade plastic which rotates around the threaded, fixed, mandrel and glides over various surfaces or, which may be locked in a static position to provide a skidding, or "grinding" effect.
