Late 80’s crankset Shimano Biopace FC-B124 Biopace Crankset 175 mm

Up for auction is a Shimano Bio Pace triple crankset (48T, 38T, 28T) with 175mm arms. Bolts are not included. The chainrings look to be very lightly used, and are in very good condition. Included with this set is a Shimano Deore rear derailleur, exact model unknown; a set of Shimano 3X6 Light Action shifters, the 7 speed is SIS and the 3 speed being friction rather than indexed (I believe); one set of Shimano BL MT-60 brake levers. This entire set of parts came from one bike years ago, and the parts have been boxed up for quite awhile. Shifters function, and derailleur has some scrapes, but appears straight. There is some pitting and fading of the paint on the shifters.
