This crankset is original and is in great working condition. It came off of a 1979 Stormer CYC which has been in my garage for the past 30 years.
The cranks are 1979 Ashtabula and the sprocket is a 44 teeth Mongoose Sugino made in Japan.
It comes with a Tange Seiki Co LTD nut.
The bearings are in good shape except one ball falls out.
