5-Speed CYCLO 72 Freewheel Vintage Touring Bike 14-26 34.7x100 Eroica RC27

The CYCLO 72 five-sprocket freewheel steps from 14 to 26 teeth, a ratio window that works well on a vintage touring bike when the route includes long false flats and laden climbs. Threaded at 34.7×100, it threads directly onto period hubs built to the old French standard.

Why this five-speed block is worth a closer look

Five speeds keep the drivetrain simple, and the 14-26 range gives you a useful bottom end without losing the tighter cadence steps up top. The unit is made of steel, and the specification shows no oxidation. Cosmetic micro-scratches from storage are possible; the photographs do form part of the description.

For another classic French-thread option, the ATOM 66 5-speed freewheel with 14-26 teeth offers a very similar ratio spread. If your project calls for a slightly lower gear, the Cyclo 72 with 16-24 teeth is geared for hillier ground.

On a period-correct rebuild, the right block matters more than the frame colour. The 34.7×100 thread is non-negotiable if the hub is French, and a 14-26 five-speed is a safe, rideable choice when you want a gearing range that does not force you to walk the steep bits.
