The science of

forged.

Forging isn’t a finish, it’s a fundamentally stronger way to build a wheel. This is what happens under 2,700 tonnes of pressure.

Under pressure

Grain structure

Forging aligns the aluminium’s grains to the shape of the wheel, stronger in every direction.

6061-T6 billet

A single solid block of aerospace aluminium, none of the porosity of casting.

T6 heat treatment

Solution, quench and age for maximum hardness and toughness.

−38% mass

Less unsprung weight means sharper steering and more grip.

Look inside the metal

It's in the

grain.
Forged, aligned grain

The grain runs unbroken along the lines of force. Nothing to tear along.

Cast, random porosity

Air pockets and random grain form weak points under load.

Technology

Forged

beats cast.

Forging aligns the aluminium’s grain structure under 2,700 tonnes of pressure. The result: stronger, lighter and dramatically more fatigue-resistant than a cast wheel.
