One of Sugino's various copies of Campagnolo's Gran Sport/Nuovo Record cranksets
171mm crank arm length
Production on these began in 1972, difficult to date this example exactly. My best guess would be late 1970s considering the other items that came from this collectors lot.
"47-B" inner stamp on non drive crank arm
Crankset is in good condition for its age showing light signs of wear with light scuffing and scratching to some surfaces. Pedal threads show some wear and may require attention. Chainrings show light signs of wear from use with residue build-up on inner ring. Includes Sugino dust caps. No chain ring bolts included. See pictures for details.
