Overview
The Shimano Dura-Ace MF-7400 multiple freewheel marked a revolutionary leap in drivetrain history, delivering the surgical precision of the newly introduced Shimano Index System (SIS) to traditional threaded hub wheelsets. Engineered with Shimano's twisted Uniglide (UG) tooth profiles and a sealed internal ratchet mechanism, it provides whisper-quiet engagement and effortless shifting under load.
This authentic 6-speed freewheel is preserved in museum-grade NOS (New Old Stock) / NIB (New in Box) condition. It remains factory-sealed in its original protective plastic wrapping inside the authentic silver Dura-Ace packaging, complete with matching factory end label and original printed service instructions. Featuring the classic, beautifully spaced 14-24T ratio (14-16-18-20-22-24T), this is the definitive period-correct drivetrain component for mid-1980s racing builds and collectors seeking untouched Japanese mechanical perfection.
