Product explanation ■ This is a 13 mm diameter machined aluminum roller with a wide range of roller settings.
The main body has a 520 bearing embedded to achieve smooth rotation.
Since there is no rubber or plastic ring on the outer circumference of the roller, it can be attached to the front and back.
In addition, compared to 13 mm ball bearings for rollers, it is less than half, and it is light with about 1.7g for 2 pieces.
It can be attached to every Mini 4 wd car including Mini 4 wd PRO.
