Vintage 1979/80 Gipiemme Bianchi "Dual Sprint" crankset with crank bolts & dust covers. 52/42 chainrings, 144BCD, 170mm arms, Italian pedal threads. Crank arms are stamped Bianchi on the back side. Taken from a late '79 Bianchi and appeared to be original equipment so we date this accordingly. In very nice condition for its age, clean tapers and threads, some scratches to the left crank arm.
