️ Main features and functions

1. Rigid Double V-frame

The Avantgarde 4 DV uses a Double V-frame architecture, which means that two „V”-shaped elements intersect to create a stable structure that is resistant to lateral forces and optimized for maximum energy transfer to propulsion. This structure allows the user to have a quick reaction during pushing and a direct response to changes in direction.

Compared to traditional frames, DV geometry offers a better maneuverability, as well as a superior stability at higher speeds or in tight turns.

2. Advanced ergonomic adjustments

Avantgarde 4 DV allows a variety of adjustments that ensure the chair adapts to the biomechanical needs of each user:

• Seat width and depth: can be customized for a perfect fit;
