EFFIGEAR is first and foremost the story of a committed mountain biker, Guy Cavalerie.

EFFIGEAR is also a beautiful story of passion. The passion to be on your bike, to ride, to get off fast and clean.

EFFIGEAR is above all an idea, a concept that germinated in the mind of this rider: "What if we created a gearbox?

After years of full-scale tests and the arrival of David Roumeas to the project, they are ready in 2011 to present their innovation to the cycling world. It will be at the Mountain of Hell (Les 2 Alpes), and the Roc d'Azur (Fréjus). The reception is enthusiastic and leads to the creation of the EFFIGEAR brand.

They then decided to build their own bicycle frames. The name was found: CAVALERIE, named after the founder. A name that recalls horses, their power, their elegance and their unfailing loyalty.

The story...

Today, Guy has stepped away from running the business, and is putting all his experience to work on the image of both brands. David, alongside Vincent Lecornu, commercial director, took over the project in 2019.

David and Vincent chose to set up in Maclas, in the Loire, one of the most beautiful playgrounds in the Massif Central. Maclas is also not far from Saint-Etienne, the historical capital of cycling, and this is perhaps not by chance.

EFFIGEAR also collaborates with major industrial groups to offer their technologies on mountain bikes of course, but also on road bikes, city bikes, cargo bikes or gravel. EFFIGEAR anticipates and is part of tomorrow's mobility, for individuals and professionals alike.

Passion and constant innovation are the real leitmotiv of these pioneers of the made in France gearbox, which will revolutionize the way you ride your bike.
