The Aurum Magma Essentia is a cheaper and more comfortable addition to Ivan Basso and Alberto Contador’s bike range.

The Grand Tour winners turned bike designers claim the Essentia retains the “essence” of the Aurum Magma.

The original Magma arrived in September 2020 as the duo’s first release and is an all-round race bike with a 800g-frame, costing almost £9,000.

The Magma Essentia shares the Magma’s aggressive geometry and is claimed to be as aerodynamic. Unsurprisingly, therefore, the Magma Essentia’s profile is very similar to that of the Magma.

Like the Magma, it has a large, traditional rear triangle instead of dropped seatstays, which Aurum claims improves responsiveness when climbing, while D-shaped frame tubes are said to reduce aerodynamic drag.

The Magma Essentia is heavier and less stiff, though, according to Aurum.

The Magma Essentia frameset is optimised for 25mm to 28mm tyres but has clearance for 30mm-wide rubber.

Aurum

Aurum says the Magma Essentia is for “advanced training” and, like the Magma, for competition.

But only the Magma is sufficient for “pro competition”, according to the brand.

Aurum Magma Essentia specs

Starting at €5,699 for complete builds, the Aurum Magma Essentia comes with the new 12-speed Shimano Ultegra R8170 Di2 or SRAM Force eTap AXS groupsets.

Unlike the Magma, the Magma Essentia is not for sale as a frameset only.

The Magma Essentia builds are about a kilo heavier than the Magma, with a claimed weight in size 54 of 7.7kg in the SRAM Force eTap AXS build and 7.5kg with Shimano Ultegra.

Both builds come with a choice of deep-section carbon wheelsets from Zipp or ENVE.
