Universal wheel 14.2x8mm

Precision and lightness in every turn: universal duralumin rim 14.2x8mm

The SP021104 rim from Sloting Plus is a replacement part made of duralumin that combines mechanical strength and low weight —only 0.70 g.— in a piece measuring 14.2x8mm. Duralumin is the material of choice in slot preparation precisely because of this equation: it withstands the stress of acceleration and braking without adding mass to the rotating assembly.

Main features

• Material: duralumin
• Size: 14.2 mm diameter × 8 mm width
• Weight: 0.70 g per unit
• Fixing: M2.5 × 3 mm allen grub screw
• Contents of the bag: 2 rims + 2 grub screws
• Compatibility: universal track (Scalextric, Ninco and equivalent systems)

Function and performance

A well-centred and lightweight rim reduces inertia in every change of direction and improves grip by keeping the tyre in uniform contact with the track. Duralumin, compared to softer materials, maintains its geometry under torque and lateral forces in corners, resulting in more predictable and consistent behaviour throughout the session.

The weight of 0.70 g. places it at the lower end of the spectrum for rims of this size, a direct advantage in starts and steering response.

Assembly and preparation

The M2.5 × 3 mm allen grub screw included in the bag allows for secure tightening and facilitates quick disassembly between sessions or when changing tyre specifications. For correct assembly:

1. Insert the grub screw into the central housing of the rim.
2. Place the chosen tyre onto the rim before mounting the assembly onto the axle.
3. Tighten with the appropriate allen key without exceeding the recommended torque to avoid damaging the axle.
4. Check the centring by turning the axle by hand before placing the body.

Common mistakes

The most common mistake is over-tightening the grub screw, which can deform the axle or hinder future removals. Another point to watch is not checking the centring after assembly: a slightly eccentric rim generates vibration at high speed and wears the tyre unevenly. Sloting Plus includes the grub screws in the bag precisely to prevent the use of incorrect size fasteners.

Frequently asked questions

Which tyres is this rim compatible with?

With any indoor slot tyre compatible with 14.2 mm diameter and 8 mm width. Check the Sloting Plus catalogue to see which rubber references fit directly.

Can I use this rim on Sport track (Scaleauto, Slot.it)?

The reference is catalogued as universal, that is, designed for Scalextric and Ninco track. For Sport track, it is advisable to verify that the axle diameter of the chassis matches the rim housing before mounting it.

Is the M2.5 × 3 mm allen grub screw standard?

Yes, it is a widely used size in slot replacements. If you need to replenish the grub screws separately, you will find them in our fasteners and preparation accessories section.

How many rims does the bag contain?

The bag contains 2 rims and 2 grub screws, sufficient to equip a complete axle (front or rear).

Is it necessary to true the rim before mounting the tyre?

It depends on the level of competition. For recreational or club use, the factory finish is more than sufficient. In high-competition preparations, many drivers perform a small truing on the rim to ensure perfect centring and maximise grip.

The SP021104 is a duralumin universal rim measuring 14.2x8mm and weighing just 0.70g, designed for slot car preparation. Manufactured by Sloting Plus, it comes in a pack of 2 rims and 2 allen grub screws M2.5x3mm, making it ready to fit straight out of the bag. Ideal for club racers and serious hobbyists looking to reduce unsprung weight and improve tyre consistency on Scalextric and Ninco compatible track systems.
