THE MECHANICS OF
INSTANT SHIFTING.

No derailleur. Only innovation.

CONTAVELO introduces a completely new system that hides 

the entire gear mechanism inside the crank.
The operation couldn’t be simpler: 

a single, subtle action—just a 45-degree 

backward pedal rotation.

Instantly, the ratio shifts from 1:1 → 1:0.75, and your bike switches into Climb Mode, turning hills into something that 

feels like flat ground.
Lighter. Smoother. More intuitive. 

And now, all that’s left for you to do is—Enjoy the ride.
