4 speed freewheel Cyclo 72

Cyclo 72 4-speed freewheel: the heart of a vintage road bike transmission

In the world of classic cycling, every component tells a story—of an era, a style, a way of riding. The Cyclo 72 4-speed freewheel, an iconic piece from the 1960s–70s, is a perfect example of vintage road bike drivetrain engineering. Let’s take a closer look at this rare and technical gem, highly sought after by enthusiasts of vintage bike restoration.

A key part of the vintage drivetrain

The 4-speed freewheel is a vital element in the drivetrain system of an old-school racing bicycle. Screwed onto the rear hub, it houses the sprockets that, in combination with the rear derailleur, allow riders to adapt their pedaling effort to the terrain. The Cyclo 72 model captures the mechanical charm of a time when simplicity meant efficiency.

Technical features of the Cyclo 72

What makes the Cyclo 72 stand out:

• 4 steel sprockets, precision-machined, typically ranging from 14 to 24 teeth—ideal for flat and moderately hilly rides.

• French-threaded body, compatible with most French-made road bikes from the 1970s.

• Works with vintage Cyclo, Huret, or Simplex derailleurs, often found on Reynolds or Vitus frames.

• Sturdy freewheel body, built to last—even after decades of use.

• A distinctive clicking ratchet mechanism, a nostalgic sound instantly recognizable to vintage bike lovers.

A true-to-era riding feel

Unlike modern cassettes, the Cyclo 72 4-speed freewheel demands precision when shifting gears. The gear changes are firm—sometimes a bit raw—but always authentic. With downtube shifters, each gear change offers a direct, mechanical connection that brings the rider closer to the machine.

Perfect for restoration projects

Restoring a vintage road bike with an original 4-speed freewheel is a tribute to authenticity. Whether you're rebuilding a Peugeot PX10, a Mercier rose, or a classic Gitane racer, the Cyclo 72 is the ideal period-correct choice.

It pairs perfectly with a double crankset, creating a 2x4 setup—standard on road bikes before triple chainrings became popular.

Conclusion

The Cyclo 72 4-speed freewheel is more than just a drivetrain part—it’s a piece of cycling history. Sturdy, functional, and undeniably retro, it continues to charm collectors, vintage bike restorers, and anyone who longs for the raw, mechanical feel of classic road cycling.
