[Useful parts for improving machine performance and setting]
A machined aluminum roller with a diameter of 13 mm that expands the range of roller settings.
520 bearings are embedded in the main body to achieve smooth rotation.
It doesn't slow down in corners as much as a roller with a rubber ring around it.
In addition, it is also a point that it is about half or less than the 13 mm ball bearing for rollers, about 1.7 gram for 2 pieces.
Bright red makes the machine fashionable.
Including Mini 4WD PRO, it can be attached to each Mini 4WD car.
Lightweight and strong aluminum roller
