(partially from BikePro.com) The Synchro series was originally designed for use specifically with the Campagnolo Syncro system (despite the difference in spelling); the rear portion of the Synchro freewheel has a stamped Campagnolo logo. The cog teeth have a V-notched tops to aid in shifting. The body of the Synchro (1990 and 1992) is unplated black steel (like Reginas earlier models) and the 90 cogs are zinc plated, rather than the chrome finish of the 1992 America. The date of manufacture, 1989 is consistent with the release of Syncro II. The 90 Sycnro used the industry standard 5.0 cog spacing introduced by Suntour (Ultra 6) for 7 freewheels and later cassettes. The later 1992 Synchro 8 speed spacing was tweaked toward the 4.8 standard of Shimano/Suntour and eventually SRAM and Sachs, to make them more universally compatible for indexing, while Campagnolo stayed with the 5.0 8 speed spacing. This was also Regina's break from Campagnolo that also included Regina releasing it's own component gruppo "Extra", which was a re-branded Sachs gruppo.
