5-Speed CYCLO 72 Freewheel, Vintage Bike, 355g, 14-24, 34.7×100, Eroica RC48

The CYCLO 72 delivers five ratios across a 14-tooth top cog and a 24-tooth climbing gear. The steel body weighs 355 g and carries a 34.7×100 freewheel thread, the standard found on numerous French hubs from the period. Oxidation is present on the unit, exactly as documented in the photographs that form part of this condition report.

What this freewheel offers a vintage drivetrain

A 14-24 spread keeps shifts predictable on rolling terrain. The five sprockets are made of steel, a material choice that matches the component's original technical brief. The thread specification — 34.7×100 — matters most here: it determines hub compatibility and must be checked against the wheel before fitting. Pair it with a compatible hub and a period-correct derailleur for a coherent setup.

The freewheel category is the best place to check compatibility before mounting. For wheels that already spin true, a look at our Chains range helps complete the transmission side. Riders assembling a French-period road machine might also consider the 7-Speed SACHS Freewheel for wider gearing, though its threading differs from this 34.7×100 unit.
