Shimano Dura-Ace MF-7400 7-Speed Multiple Freewheel (14–24T, NOS in Factory Plastic)

The Story
Introduced as the backbone of the legendary Shimano Dura-Ace 7400 series, the MF-7400 7-speed multiple freewheel set the benchmark for indexed shifting precision in the late 1980s and early 1990s. 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.

Stamped 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.
