AURUM’s first gravel model, MANTO, is the ultimate racing gravel bike

Simply put, it’s a MAGMA for gravel. It follows the same principles and same high-performance spirit as MAGMA, but with bigger wheels and gravel specific geometry. It takes all the riding and testing experience from Alberto and Ivan, then adds all the experience from AURUM to design and develop a top-level bicycle.

We have spent countless hours riding it, fine-tuning it and thinking about how to make it better, to be worth of sitting next to the MAGMA in our bike catalog

Driving characteristics

Creating the fastest high-performance gravel bike on the market is a balancing act between different riding characteristics:


For power delivery and quick, confident handling and cornering.


For long rides and ensuring that the rider can always perform at the highest level.


Reducing aero drag for the best efficiency and pure speed, on and off road.


For a lively feel and to save energy, without compromising stiffness and comfort.

During the development of MANTO, the AURUM team led by Contador and Basso spent countless hours testing different prototypes. This was a necessary exercise to confirm the numbers drawn for the geometry, both for the handling and fitting. But even more importantly to fine-tune the bike’s riding characteristics. These characteristics are defined not only by the shape and size of the tubes, but very crucially by the materials and manufacturing used to mold them.

By producing several carbon layup iterations, the engineers at AURUM already had a good idea of the frame’s behavior by design, thanks to their experience and the data collected in the test lab and the stiffness bench. By the time Alberto and Ivan threw their legs over the saddle of the MANTO, the frame and fork had already gone through rigorous lab testing, exceeding the usual bike industry standards and European norms, to ensure the safety and solidity of the structure. But beyond that, what differentiates an excellent bike from just a good bike is the riding feel, the sublime balance of riding characteristics (stiffness, comfort, light weight and aerodynamics all working in unison) that were set as the main goal for this project. After many kilometers of tests on tracks and roads, we can consider the results of MANTO to be excellent and proudly launch this product on the market to join MAGMA in the AURUM catalogue.
