At MMR, we understand gravel riding as a terrain where performance, reliability, and speed make all the difference. That's why we've revamped the Simun range, our competition-oriented gravel bike, with new colors and updated components that reinforce its racing character.

SIMUN 30 +

Di2 technology and perfect balance for racing

Equipped with Shimano GRX RX825 Di2 , the Simun 30 offers fast, reliable, and extremely precise electronic shifting. Its build stands out for its balance of performance, comfort, and control, making it ideal for long distances and races where consistency is key.

Highlights include its FSA SLK Carbon cranks and VISION components with its VISION SC48 wheelset and integrated METRON 5D carbon handlebar
A perfect option for cyclists looking for proven electronic technology and competitive performance in any gravel scenario.

SIMUN 50 +

Accessible gravel racing with AXS technology

The Simun 50 features SRAM Rival XPLR AXS E1 , bringing gravel-specific electronic shifting to a wider audience. It maintains a distinctly competitive focus, with a reliable build ready for hard training and confident racing.

It is the ideal entry point to electronic gravel racing within the Simun range.

SIMUN 70 +

Versatility and reliability to get started in competitive gravel riding

The Simun 70 is the most affordable option in the range, equipped with mechanical Shimano GRX, offering robustness, ease of maintenance and proven performance.

Designed for those starting out in competitive gravel riding or looking for a fast and reliable bike for intense training and first races, without sacrificing the racing DNA of the Simun.

The Simun was born for those who seek speed off-road, for those who line up at the start with a numbered race number or compete against the clock on each stage. In this redesign, we've opted for a more aggressive and modern aesthetic , with new color combinations that reflect its competitive DNA and its distinctly sporty focus.

Along with the image, we have revised the assembly to offer updated components, designed to ensure precise operation, reliability in demanding conditions, and consistent performance on long days of fast and technical gravel riding.

The new MMR Simun maintains the balance between lightness, efficiency and control that competition demands, making it a tool prepared to perform at its best in both gravel races and intense training.

With this update, we continue to focus on high-performance gravel and the constant evolution of our models, always with a clear objective: to help you compete at the highest level on any terrain.
