Engineered specifically for the Dura-Ace SIS (Shimano Index System) drivetrain, it combines ultra-hardened Uniglide sprockets with a labyrinth-sealed freewheel body that delivers the unmistakable, crisp Dura-Ace ratchet sound and silky-smooth rotation.\u003c\/p\u003e\n\n\u003cp\u003eStamped with the Shimano date code \"PD\" (April 1991), this specific MF-7400 is an absolute time-capsule find for collectors. It comes in the highly desirable 14–24T all-round road ratio (14-15-16-18-20-22-24T), perfectly balancing flat-road speed with practical climbing gears. What makes this set extraordinary is its pristine presentation: It is still sealed in its original plastic wrap with the yellowish factory preservative grease intact, housed in the original silver-and-blue Dura-Ace retail box alongside the original fold-out service instruction manual.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cbr\u003e\n• Brand: Shimano\u003cbr\u003e\n• Groupset \/ Model: Dura-Ace (MF-7400)\u003cbr\u003e\n• Part Number: 2-12371170\u003cbr\u003e\n• Date Code: PD (April 1991)\u003cbr\u003e\n• Country of Manufacture: Japan (Stamped Shimano Japan \/ VIA)\u003cbr\u003e\n• Speed: 7-Speed (Dura-Ace SIS Index \u0026amp; Friction compatible)\u003cbr\u003e\n• Tooth Progression: 14-15-16-18-20-22-24T\u003cbr\u003e\n• Tooth Profile: Shimano New Uniglide (twisted tooth tips for smooth shifting under load)\u003cbr\u003e\n• Body Mechanism: Labyrinth Sealed Mechanism\u003cbr\u003e\n• Thread Standard: Standard BSA \/ ISO \/ English freewheel thread (1.37\" x 24 tpi)\u003cbr\u003e\n• Included: MF-7400 freewheel (factory sealed in plastic), original fold-out service instruction manual, and original Dura-Ace cardboard box\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCondition\u003c\/strong\u003e\u003cbr\u003e\n• \u003cstrong\u003eCosmetic:\u003c\/strong\u003e New Old Stock (NOS) \/ New In Box (NIB).
