Shimano Dura-Ace MF-7400 7-Speed Multiple Freewheel (13–21T) in Original Box

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 mid-to-late 1980s. 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 "LC" (March 1987), this MF-7400 features the classic close-ratio 13–21T racing progression (13-14-15-16-17-19-21T) and comes complete with its original silver-and-blue Shimano Dura-Ace retail box. An essential, period-correct component for any high-end 1980s road bike restoration running classic screw-on freewheel hubs.
