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 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.
