Bearings are a fundamental component of the skate and guarantee (if correctly maintained) an optimal level of roll for the wheels.
The bearings speed max are designed for high performance and represent the best option for this discipline.

• The Speed Max are the only bearings equipped with 8 balls/spheres rather than 7

• This, coupled with the minimal level of radial movement which evenly distributes the load on the spheres, guarantees an unparalleled level of smoothness and roll

• Suitable for all frames with 7 mm axles

• Reinforced steel casing with an 8-ball cage, immersed in carbon to provide additional self-lubrication.

• Hermetic bilateral protection to prevent the entry of dust.

• Provided in sets of 16 (It is at the discretion of each reseller to sell units in smaller quantities).
