With the introduction of the 1st Dura Ace grouppo in the mid 1970s Shimano stated their intention to challenge Campagnolo’s almost monopoly on road racing groupsets, the quality, finish and light weight were matched by the excellent performance of the parts. The distinctive shape of the chainrings from the GA-200 cranks is beautiful and this black 44 tooth version is ideal if you have a worn one on your chainset.
