A retired French engineer designs a revolutionary crankset that increases the power of bicycles by 10%

Jacques Cerdan, great-nephew of boxer Marcel Cerdan, spent his career behind the drawing board of the automotive industry. When he retired, he devoted himself to his passion: cycling.

More than 15 years ago, he envisioned a new crankset that would increase horsepower by 10%, but his friends at the cycling club weren’t convinced.

The first pieces were made by myself with the means I had at hand. There are many people who did not want to try my invention. These people could ask me one day to provide them with a pedal board.

A small revolution.

That day may have come. A businessman from Marseille decided to industrialize the Cerdan system, which revisits the classic pedals.

It’s not perfect, a pedal stroke, there is a dead zone, that is to say that when you have one foot down and the other up, you cannot distribute the power, that does not turn.

With the new system, the top pedal will already be tilted, ready to receive power.

It provides a power gain, increases efficiency and brings comfort.

We realize that we can have a much higher cadence, and therefore a much greater power gain immediately.
