AurumMagma
The second-generation Magma from Alberto Contador and Ivan Basso's AURUM: a light race bike (780 g frame in size 54) that adds NACA-profiled tubes to the rear half, a wider fork stance, 35 mm tyre clearance and a one-piece AURUM bar with hidden cables. AURUM estimates about 7 W saved by the frame and 10 W more by the bar at 45 km/h. Electronic groupsets only.

Our verdict
Overall
out of 100, average of 6 categories
A light, pro-raced all-rounder with a one-piece bar offered in 15 sizes, 35 mm tyre room and standard T47 and UDH. Its aero gains come from CFD estimates rather than published tunnel data, and it is costly for what the builds include.

Short front centre: more weight on the front wheel, which can make the front feel lighter to steer.

Good to know
Design
AURUM claims 780 g for a size 54 frame, 375 g for the fork, 170 g for the seatpost and 320 g for the integrated bar, and says a complete bike of around 6.5 kg is possible. It quotes no complete weight for its own builds.
SourceFit
AURUM's size guide says the Magma comes in six sizes but lists five (48-58); the UCI approval also covers six sizes from 48 to 58.
SourceHistory
Cyclingnews reported the launch of the second-generation Magma on 27 May 2024, about five years after the original; the Polti-Kometa team raced it from the first stage of the 2024 Giro d'Italia.
SourceVersions
AURUM also sells the frameset without its integrated handlebar (the bar is a €550 option in the frameset configurator), and its frame specification lists a standard 28.6 mm fork steerer.
SourceVersions
AURUM's prices disagree between pages: the Magma page says complete bikes from €7,499 and framesets from €4,099 'tax excl.' (the Spanish page shows €9,073.79 and €4,959.79, i.e. with 21% VAT), while the configurators total €8,299 for the cheapest complete bike and €4,749 for the frameset. The builds here use the configurator totals. Away from Europe the configurator shows the same figures in US dollars with a note that they exclude VAT and import costs.
