Shimano Dura Ace 1st gen crankset 52/39 chain rings highly polished 170mm

  

This vintage Shimano Dura Ace 1st generation crankset is in good overall condition. It has been highly polished by the professional chrome and metal polishing shop I regularly use.

Chainrings are 52 tooth and 39 tooth both with a 130 mm bolt circle diameter that is standard for Shimano. The crank set has 170 mm crank arms.

This crankset will be ideal for a late 1970s through mid 1980s bike Japanese bike restoration. Please note that the photos do not accurately show the full high quality polish of this crankset. The glare from the sun or flash would minimize other details if those photos were shown.

I added a photo showing this crankset on a bike that better displays the polishing.
