Shimano Dura-Ace MF-7400 7-Speed Multiple Freewheel (13–26T Climbing Ratio, NOS)
The Story
Introduced as the heart of the legendary Shimano Dura-Ace 7400 series, the MF-7400 7-speed multiple freewheel defined indexed shifting precision in the 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 "LF" (June 1987), this New Old Stock (NOS) example features the rare and highly sought-after 13–26T climbing progression (13-15-17-19-21-23-26T). Because 26T is the maximum sprocket capacity officially supported by short-cage Dura-Ace 7400 rear derailleurs, this freewheel is the ultimate Holy Grail for L'Eroica riders, alpine climbs, and high-end 1980s road bike builds that demand both period-correct authenticity and practical climbing gears.
