Bring your vintage bike back to life with a Cyclo 64 5-speed screw-on freewheel

In the world of vintage bicycles, every component tells a story, combining style with mechanical precision. Among the essential parts of an old-school drivetrain, the screw-on freewheel plays a central role.

What is a screw-on freewheel ?

Before the rise of modern cassette systems, older bicycles were equipped with screw-on freewheels. Unlike today’s freehub and cassette setup, this system threads directly onto the rear hub. The freewheel houses both the sprockets and the ratcheting mechanism, allowing power transfer when pedaling and coasting when not.

The Cyclo 64 freewheel: a vintage classic

The Cyclo 64 is a legendary screw-on freewheel used on many French bikes from the 1960s and 70s. It was commonly found on road bikes, touring bicycles, and high-end city bikes.

Technical specifications:

• Speeds: 5 sprockets

• Threading: french standard (34.7 mm x 1 mm)
