Black pearl is Ethic's sister brand, created in 2012 with the aim of bringing you the very best in high-end wheels.
The core is machined from a block of 7075-t6 aluminum to the highest standards of precision.
The rubber is molded in France, using a polyurethane of unrivaled quality.
This gives it a rolling speed light years ahead of current standards.
 
The dual-compound versions also feature a unique technology that combines soft compound in the centre for greater flexibility and comfort, and hard compound on the outside to increase the wheel's durability and strength.
