The kind with "flat-face" arms, engraved logo, 170-175 mm, with or without chainrings, and with or without matching BB (116 mm spindle, for 68mm shell, English thread). Condition of square sockets and pedal threads must be good, arms straight, but cosmetics secondary. Have Off-Topic Dura-Ace crankset +BB, if anyone wishes to trade.
