Special front wheel conversion kit with industrial bearings and a complete wheel axle, compatible with the front Grimeca Snowflake cast wheel on your Hercules Prima 2, 3, 4, 5, and Optima moped.
The benefits of this conversion kit include improved stability, reduced vibrations, and longer bearing life.
The set consists of the front wheel bearing kit with two ball bearings from SKF, the world’s leading ball bearing manufacturer, an aluminum spacer tube, and the complete axle set from the quality brand swiing® ingenious.
The plug-in axle includes all necessary washers, nuts, and spacer sleeves.
The two lower nuts, on the speedometer side, are already pre-assembled in their fixed positions. This ensures the necessary spacing is provided, eliminating the need for time-consuming spacing adjustments.
The colored markings show you where to install each part:
- red mark: hub (not visible in the picture)
- green mark: brake anchor plate
- yellow mark: Spacer for the speedometer drive (this spacer is not needed if a drive is installed)
- blue mark: fork legs
When you purchase this complete set, you’ll save a significant percentage off the retail price of the individual parts.
A sophisticated product from the premium brand swiing® that meets the highest standards.
