Details:   The Shimano 600EX groupset was made in a multitude of variations and generations.  Often, more than one variation was being produced at the same time.  Included in the Shimano 600EX groupsets is the easily recognizable Arabesque group with detailed engravings and designs.  The 600EX group went from friction shifting at its introduction, to 6 speed SIS shifting later in the 1980's.
