Made of low-friction leaded brass.

For chassis with 4.6 - 4.8mm hole anchoring.

Only weighs 0.39g.

The first bushing in the world created with the ability to self-lubricate. A small conical tank and a tiny hole of 0.2mm allows lubricant to flow slowly to the axle, lubricating it constantly. The inner groove reduces the contact area with the axle by 50% while acting as a lubricant reservoir.

Ideal for short- and medium-duration races.
