MAILLARD SACHS COURSE 1991 7-Speed Freewheel 14-24 Vintage BSC 1.375x24 D10

The MAILLARD SACHS COURSE freewheel carries a 1991 date code and a 14-24 tooth spread across seven speeds. This is a vintage drivetrain unit, threaded for the British standard BSC 1.375x24 bottom bracket shell. The gear range covers both flat sprinting and steep climbing, the kind of spread that suited early-90s racing setups well.

What the 14-24 Range Delivers

Seven cogs from 14 to 24 teeth give you a tight cadence progression at the top end while still offering a bailout gear for long ascents. That 24-tooth low sprocket paired with a standard road double of the period keeps the whole drivetrain manageable without demanding a huge freewheel body.

The BSC 1.375x24 threading remains one of the most widely supported standards in vintage road and touring bikes. If your hub uses that thread, this freewheel screws on directly. No adapter, no compromise.

Condition as Documented

The accompanying images form the full condition record. This is a used freewheel from 1991, so minor wear, cosmetic traces, or storage marks may be present. No major damage is noted in the source data. The photos show exactly what you are getting, and they carry the same weight as a written description here.

For those building up a period-correct racer from the early 90s, finding a MAILLARD SACHS freewheel in this range is a step toward closing the gap on a complete drivetrain. Check the pictures to assess the state of the cogs, the threading, and the locking ring before committing.

Compatibility Notes

This freewheel fits hubs with BSC 1.375x24 threading. That is a common British/ISO standard, but always verify your hub's thread pitch and diameter before ordering. A mismatched thread can destroy both the freewheel and the hub shell.

For those hunting comparable period components, a SACHS 7-speed freewheel from 1993 in 12-26 is also listed — useful if you want a wider range for hillier terrain. And when the freewheel is mounted, a matching vintage rear derailleur completes the picture; the Campagnolo Super Record rear derailleur from the Pat. 82 era sits comfortably with this kind of gearing.
