Offset line crown 28Z bronze insert

The Slot.it inline Offset crown gear with bronze insert: reliable transmission for real competition

The SIGO28-BZ crown gear is a transmission component developed by Slot.it for those building or preparing cars with inline motorisation —motor positioned inline with the rear axle, longitudinally— and using the Offset pod from the same brand. Its 28 teeth place it in a balanced gear ratio, suitable for both technical tracks and fast layouts where stability in power delivery makes a difference.

Main features

• 28 teeth for a versatile and progressive gear ratio.
• Bronze insert: greater wear resistance compared to standard plastic versions, and lower friction on the axle.
• Axle diameter: 2.38 mm, the usual standard in Slot.it transmission sets.
• Designed exclusively for use with Offset pod: its geometry is not interchangeable with other configurations.

Function and performance

The bronze insert is not a minor detail. In long running sessions or club competition, crown gears with plastic cores can suffer from micro-play that translates into loss of efficiency and noise in the transmission. Bronze reduces that wear, maintains the fit on the axle for longer, and contributes to cleaner and more predictable driving. For those fine-tuning every tenth, this difference is noticeable.

Compatibility and installation

This crown gear is designed exclusively for the Slot.it Offset pod in inline configuration. Before installation, it is advisable to check that the motor pinion is compatible in module with the crown gear to ensure correct meshing without play. Slot.it specifies a 2.38 mm axle, so this is the diameter that the rear axle of the set must have for installation.

A correct fit also involves checking the distance between the pinion and crown gear centres: too tight generates heat and premature wear; too loose causes skipping and noise. Slot.it provides specific adjustment tools for this process.

Ideal for…

• Preparers and drivers using Slot.it chassis with inline configuration and Offset pod.
• Competition on Sport track (Scaleauto, Slot.it) where transmission reliability is paramount.
• Enthusiasts seeking greater durability compared to conventional plastic crowns.

Common mistakes

• Using it with Sidewinder or Anglewinder pod: this crown gear is specific for inline with Offset pod. It will not function correctly in other configurations.
• Not checking the pinion module: the bronze insert does not compensate for poorly matched meshing. Always check compatibility with the motor pinion.
• Excessive tightening on the axle: bronze is durable, but forced installation can damage the insert. Use the appropriate tool.

Frequently asked questions

Can I use this crown gear with any inline motor?

The crown gear is compatible with any motor in inline configuration as long as the pinion has the correct module and the set is mounted on the Slot.it Offset pod. It is not designed for pods from other brands or for Sidewinder or Anglewinder configurations.

What real advantage does the bronze insert offer over plastic?

Bronze offers greater wear resistance and a lower coefficient of friction on the metal axle. In intensive use, the crown gear maintains its fit for longer, resulting in a more efficient and quieter transmission throughout the session.

Which pinions does this crown gear combine with?

Slot.it does not specify the exact pinion in the product description, so we recommend consulting the Slot.it transmission chart or contacting us to ensure that the pinion module is correct for this 28-tooth crown gear.

Is any special tool required for installation?

It is recommended to use Slot.it crown gear mounting and extraction tools to ensure a clean fit on the 2.38 mm axle without damaging the bronze insert or the rear axle.

Is this crown gear valid for Scalextric or Ninco track?

The crown gear itself can be mounted on any car that uses the Slot.it Offset pod, regardless of the track it runs on. Scalextric and Ninco tracks are of a universal type; Sport track (Slot.it, Scaleauto) does not affect the choice of crown gear, which depends on the chassis configuration, not the type of track.

The Slot.it SIGO28-BZ is a 28-tooth inline offset crown gear with a bronze insert, designed for Slot.it offset pod setups in 1/32 scale slot car racing. Compatible with 2.38 mm axles, it delivers improved durability and transmission efficiency over standard plastic crowns, making it a preferred choice for club racing and serious builders using Sport track systems.
