7-Speed SACHS MAILLARD Freewheel Vintage Racing Bike 1991 16-28 BSC 1.375x24 Eroica RC24

Gear Range and Drivetrain Behaviour

The 16-28 spread on this 1991 freewheel gives you a useful window for lumpy terrain: the 16-tooth sprocket keeps the chain moving briskly on the flat, while the 28-tooth gear offers relief on longer drags. Seven cogs provided the step changes that period road drivetrains relied on, and the BSC 1.375x24 threading bolts it straight onto hubs from that era. The body is steel. There is no oxidation to report.

Condition and Inspection Notes

On a restoration focused on period-correct gearing, this freewheel pairs well with similar units from the same generation. A slightly wider 14-24 option from the same 1991 season is available in the MAILLARD SACHS COURSE 1991 listing, while a later 13-25 eight-speed unit appears in the 1993 Sachs 8-speed freewheel.
