Effigear replaces the derailleur on bicycles with a gearbox. You can change gear at any time, noiselessly and smoothly, even when fully loaded or stationary. The gearbox features a gear pre-selection system, useful for anticipating a climb or a mountain bike crossing.

The masses are re-centred under the rider. This makes the bike more stable. The rear wheel is lighter, which helps the shock absorber make better contact with the ground.

Effigear gearboxes offer many benefits: better handling, increased durability, simplified maintenance, economy and pleasure. All with Made in France quality!
