Aurum Essentia

Essentia inherits the geometry and main qualities of the Magma such as versatility, aerodynamics and reactivity to offer a high-performance bike and complete the price range.

Special attention was paid to keep the Magma’s soul consistent throughout the size range, and let every rider, regardless of his/her height, experience the same handling. Alberto and Ivan dreamt for years to design a bike’s frame geometry based on their experience, and it was paramount that all the frame sizes would handle that way. To achieve that, the Trail figure (the combination of the head tube angle and fork offset) was the starting point. Through experience and ride testing (with different test forks and wheel sizes) the AURUM team set an ideal Trail dimension, for the best balance of quick steering but also stability at high speed. Often small frame sizes get a compromised handling, with a long Trail that makes turning slow and unlively. AURUM Magma uses two different fork offsets depending on the frame size, which combined with the proper head tube angle results in a Trail that is always lively and fun as intended, also for the smaller frame sizes.
Stack and reach will put you in a race position for out-and-out performance, yet allow comfort for a long ride. Short, oversized chainstays contribute to a climber’s configuration, while a low bottom bracket height helps achieve an assured center of gravity coupled with a generous wheelbase that delivers a reassuring stability, however fast your descent.

AURUM has transferred the incredible experience generated by the Magma model to the new Essentia, after two years of road testing with the Eolo-Kometa Cycling Team, Alberto Contador and Ivan Basso. The result is a bike with technical characteristics and performance standards similar to Magma. The essence of Magma.

A bike that shares lines and geometry with Magma while keeping the same DNA: performance

Alberto Contador

The Essentia frame is made in high-precision machined steel moulds, with perfectly aligned surfaces, requiring little work to finish and paint. Each Essentia frame is handcrafted using an advanced combination of different grades of carbon fiber, selected as the most appropriate based on the various stresses experienced in the different parts of the frame. Multiple prototypes have been produced and tested using different carbon modules, fiber orientations and resin types to find the optimal mix for each frame size. The result is strong, rigid and light.
