7-Speed SACHS MAILLARD Freewheel vintage racing bike 1992 13-26 BSC 1.375x24 eroica RC23

The 13-26 spread sits right in the middle of what a late-1980s and early-1990s road drivetrain could offer: a tight 13-tooth starting cog for flat sections and a 26-tooth climbing gear that stays predictable on long ascents. This SACHS MAILLARD unit carries a 1992 date and a BSC thread of 1.375x24, so it threads onto British-threaded hubs without re-cutting or taps.

Seven cogs, one threaded body

What matters on a freewheel of this era is not just the tooth range but how the body was machined. The seven cogs are mounted on a steel body, a choice that suits machines built for high mileage and repeated gear changes. There is no oxidation on the surfaces, which means the park gear surfaces and threads have remained clean. For a restorer working to a period-correct specification, that saves time and avoids the need to disassemble for deep cleaning before mounting.

Because this is a used component, the photographs are the primary reference for its cosmetic state. The listing images document the teeth, the threading and the body finish, and they should be read as part of the written details.

For a tighter climbing range from the same period, the 1991 SACHS MAILLARD 16-28 7-speed freewheel gives a wider step between gears. If you are building a machine with a more modern cadence control, the 1995 SACHS 14-28 7-speed freewheel is another workable alternative for mixed terrain.
