AurumEssentia
ESSENTIA is AURUM's entry into its road range: a Magma-derived race frame in the cheaper ECT-9 carbon layup, with the Magma's geometry, NACA-style truncated tubes, a size-specific aero down tube and fully hidden cables through AURUM's one-piece cockpit. Compared with the ECT-10 Magma it uses a BB386 EVO press-fit bottom bracket, a round 27.2 mm seatpost and 30 mm tyre clearance, and it is built for electronic groupsets only, with Shimano Ultegra Di2 or SRAM Force AXS E1 and Zipp 404 S wheels.

Our verdict
Overall
out of 100, average of 6 categories
The Magma's geometry, hidden cabling and one-piece cockpit for considerably less money, with Zipp carbon wheels in both builds. The ECT-9 frame gives up the Magma's T47 bottom bracket, aero seatpost and 35 mm clearance, and AURUM publishes no frame weight or aero data for it.
