This late 1970’s NR/SR crankset comes in a randonneuring setup.  A 51t big ring, and the ever so rare Campy bash ring!  

Condition

Very good used shape.  Lots of life left in the chainrings.  The arms do have some cosmetic marks, but not excessive.  Chainring guard has some pitting and one area of worn off chrome.  Arm ends have just light scuffs.  Original dust caps and chainring bolts in excellent shape.
