1995 SACHS Seven-Speed: The 14-28 Cog Stack

This freewheel carries seven steel cogs with a 14-tooth smallest ring and a 28-tooth largest ring. The thread is BSC 1.375×24, which places it in the classic British-thread family used on many European racing and touring hubs. Its 1995 production date makes it a plausible choice when you need a late-nineties transmission rather than an earlier Maillard or ATOM unit.

The photos form part of the description. Given this is a used component, minor cosmetic wear or light storage marks may be present, but no major defect such as rust, cracking, or a bent part is noted in the source listing.

Gear Progression and Hub Fit

The 14-28 spread is broad enough for rolling terrain while retaining a tight top-end progression. Before fitting, confirm your hub uses a 1.375×24 English-thread freewheel boss. The seven-speed stack should be checked against your dropout spacing and chainline, especially if the frame originally ran a five- or six-speed setup.

For a tighter five-speed alternative on a similar BSC hub, the ATOM 77 5-Speed Freewheel 14-28 offers a simpler period option. If your build centres on a later SACHS drivetrain, the MAILLARD SACHS COURSE 1991 7-Speed Freewheel 14-24 gives a closer-ratio 14-24 stack from the same brand family.
