Urano wheel 16.9x8.5 Champagne

Sloting Plus Urano Champagne Wheel: lightweight magnesium for those who fine-tune every tenth

The Urano wheel from Sloting Plus (ref. SP022323) is one of those components that makes a difference on the preparation table. Made from magnesium, it combines structural rigidity with a very tight weight of just 1.08 g per unit, resulting in less rotational inertia and a more responsive acceleration and braking.

Features and technical data

• Material: magnesium
• Dimensions: 16.9 x 8.5 mm
• Weight: 1.08 g per unit
• Colour: champagne
• Fixing: M2.5 x 3 mm allen screw
• Contents of the bag: 2 wheels + 2 screws
• Reference: SP022323

Why magnesium matters in a slot wheel

In competitive slot racing, reducing unsprung weight — the weight that rotates with the wheel — is one of the most effective ways to improve car response. Magnesium allows for a solid wheel that is dimensionally stable and has very little mass, without sacrificing the geometric precision required for a well-centred tyre mount.

Compared to standard plastic, a magnesium wheel like the Urano offers greater lateral stiffness, prevents deformation under load, and keeps the tyre seated evenly around the perimeter. The result is more predictable grip and cleaner rolling.

Assembly and preparation

The fixing system using M2.5 x 3 mm allen screw is the usual standard in competition axles. The tightening should be firm but not over-tightened: magnesium, while strong, does not tolerate the same torque as aluminium or steel. It is recommended to use a quality allen key and check the centring of the tyre after mounting, either on a lathe or by hand before gluing.

For an optimal finish, slightly true the wheel on a lathe if you are looking for minimal tolerances, and use specific slot tyre glue applied in a thin and even layer.

Ideal for…

This wheel fits particularly well in preparation projects where the aim is to reduce the total weight of the rear end without resorting to high-cost components. It is a common choice among enthusiasts competing in club categories with budget restrictions but who do not want to forgo the benefits of magnesium. It is also interesting for those who customise the aesthetics of the car: the champagne colour adds a distinctive touch compared to black or natural aluminium options.

Frequently asked questions

Which tyres is this wheel compatible with?

It is compatible with any slot tyre with an appropriate inner diameter for the dimensions 16.9 x 8.5 mm. Always check the specifications of the tyre you intend to use to ensure a correct fit without slack or excessive tension.

Can I use this wheel on the front axle?

The dimensions 16.9 x 8.5 mm correspond to a common rear axle format, but the final application depends on the specific configuration of each chassis. Check the dimensions of your setup before deciding.

Is the included allen screw made of steel?

Sloting Plus includes 2 M2.5 x 3 mm allen screws in the bag. For more details on the exact material of the screws, consult the official technical sheet from Sloting Plus or contact our team.

How many wheels are included in the bag?

The bag contains 2 Urano wheels and 2 M2.5 x 3 mm allen screws.

Do I need a special allen key for assembly?

Any quality allen key for M2.5 screws is suitable. Sloting Plus offers specific preparation tools for slot if you want to have the right equipment.

The Sloting Plus Urano magnesium wheel in champagne (SP022323) — 16.9x8.5 mm, 1.08 g — is a precision slot car component designed for club racing and performance builds. Lightweight magnesium construction reduces rotational inertia for faster acceleration response. Includes 2 wheels and 2 M2.5x3 mm allen grub screws. A go-to upgrade for slot car preparation enthusiasts looking for reliable, competition-grade parts.
