The 1R from Cinelli was introduced in the late 1970’s.  The 1R’s bar clamp design is different from that of the XA and other cinelli stems. Its bolt pushes a plate up against the bar from the back side, securing the bar in place.  The first version has the word ‘Cinelli’ across the front insert instead of the more common and later winged Cinelli ‘C’ emblem.  The top engraving is also the older “Cinelli Milano” than the later more simple typo.
