Onyx Forged

OX-M1 Obsidian

The OX-M1 Obsidian is a monoblock forged wheel with five spokes that open into a V near the hub. Each of the ten arms is hollowed by an elongated slot over its first half, then runs solid to the rim. The arms are faceted, and their edges catch the light, especially in chrome. The hub is recessed, so the face dips towards its centre; the cap there carries the OX monogram. In anthracite grey or satin black, the slots read as lines of shadow; in satin bronze, the whole takes on a warm tone.

OX-M1 Obsidian forged wheel, chrome

Offered from 18″ to 24″. It finds its place from 20″, where the slots in the arms stay clearly visible. It suits SUVs as well as powerful saloons.

How to order

For Great Britain, our checkout charges in pounds sterling. It converts the euro price at its exchange rate on the day, currency conversion charge included, so the amount in pounds is about 2% more than a straight conversion at the market rate; the amount shown at checkout is the one charged for your order. The amounts in pounds on this page are those of 4 October 2026. Delivery is included in the price, so UK import VAT (20%) applies to the whole amount in pounds. An 18″ set came to £2,780 at checkout (€3,200 on this website), or £3,336 with UK import VAT. The carrier collects the VAT before delivery, together with its clearance fee (for example, DHL Express charges £11 or 2.5% of the duty and VAT it pays, whichever is higher) and any import duty. Any import duty depends on the UK tariff in force when your wheels arrive: the amount you pay is the one on the carrier's notice, and UK import VAT then applies to it too. The details are on our Delivery to Great Britain page.
