Cyclo 72 5-Speed Freewheel 16-24t Vintage Eroica Bike 34.7x100 RC13

A 16-24 tooth spread across five sprockets gives the CYCLO 72 a distinctly compact progression. This is the kind of closely-stacked block that suits rolling terrain, where holding a steady cadence matters more than grabbing a huge bail-out gear. The unit is made of steel, and the listed condition shows no oxidation. As with all used components on this site, the photos belong to the listing and should be read as part of the technical record.

Ratio and build profile

The 16-24 tooth range is not a wide touring spread. It is a tighter cluster, the sort of block that lets a rider make small, deliberate shifts. On a five-speed wheel, that means each jump is predictable. The result is a drivetrain that feels methodical rather than abrupt. If you are piecing together a French or period-correct English build, this freewheel supplies the rear-end gearing with the right mechanical character.

For comparison, the Maillard 5-Speed Freewheel 14-26 offers a wider spread, while the ATOM 77 14-28 moves further into climbing territory.

Key specifications

• Material: Steel
• Manufacturer part number: 0000
• Country of origin: France
• Oxidation: None
• Freewheel - Cassette: 5-speed

The steel body has the weight and durability expected from a classic freewheel. The lack of oxidation is a meaningful detail here, as many blocks of this age carry surface rust on the sprockets or the lock ring. This example does not show that kind of deterioration in the condition notes.

Another period option worth checking is the Maillard 14-26 from 1977, which has a similar five-speed layout but a different tooth step.
