Technology and design

This case uses Dual Cup technology, based on two perfectly aligned aluminum cups, ensuring a rigid central junction that eliminates noise and play. The bearings used are hybrid ceramic models (ABEC5 / P5 – 2RS), offering maximum friction reduction.

The cups are made of 7075 aircraft-grade aluminum alloy, heat-treated (T6) for strength and durability. The assembly is fully sealed, with axial seals on the bearings and full protection against ingress.

The reduced number of pins makes this case lighter without compromising its strength.

Guarantee

• Lifetime warranty on cups
• 3-year warranty on bearings
