Crown Kullager

Go Project Crown bearings are different. The bearings come with a copper ‘Crown Spacer’ which slots into the centre bore hole. Compatible with all regular skate wheels and frames, the Crown system enhances performance in several ways:

The majority of grit and dirt enters the bearing through the inner ring and the shield. The Crown spacer forms a cover over this area, reducing the intake of external elements.
The Crown spacer spreads the load of the rider across a wide plateau creating greater energy efficiency.
The Crown system shifts the position of the bearing away from the frame walls and deeper into the wheel, resulting in less damage and contamination from road debris.
They are an effective solution for poor energy transfer caused by frames with plastic frame spacers.
Included:
8 bearings
8 Copper Crown spacers

Will fit out 4x skate wheels, buy 2x packs to fit 8 wheels.

Regular spacers (for use between your bearings) are sold separately.
