The Old Skool Mechanical Speedo sold by Piston Bikes (product code JBSPD) has been reported to work well on the Model A. Note that these parts are not interchangeable with Concept2's original speedometer head, cable and drive and so should be purchased as a complete kit. Also note that this setup is calibrated differently from Concept2's original unit and therefore scores will not be comparable. Visit pistonbikes.com for more information.
