This is not just a bike, it is lightness in motion.

(new) Simun

The (New) Simun is much more than a gravel bike: it's the culmination of innovation, design, and speed. Designed with a new, more aggressive, performance-oriented geometry.

More reactive, with a more aerodynamic position, because speed is the breath of the wind.

The carbon frame is the key to its exceptional performance. With the perfect combination of lightness and strength, it will allow you to maintain a high pace at all times without weight being a concern.

You'll be able to keep up with the pace of light, you'll go faster.

The Simun features a fully integrated downtube storage system, allowing you to carry your accessories and tools without compromising aerodynamics or aesthetics. This feature allows for greater comfort and space optimization.

A 3D-printed AirTag mount is also available, so you always know where your bike is.
