Vintage rare Sugino ALP double crankset for square taper bottom bracket. The original chainrings are 53 and 42 teeth, arm length 170. Teeth on the chainrings are very good yet, especially the 42. The large ring does show wear. Good threads, cleaned and ready to install. Great for a restoration project. All my auctions are no returns. Please understand this before bidding. Thanks for looking! Shipping is $11.00 and by usps.
