The braking track

3K carbon braking track with 3Diamant™ treatment to guarantee power and excellent feel when braking in any condition.


Smoothness will ensured by the well known USB™ bearing technology.

The cap and cone technology maintains the most efficient angle of contact between the bearings and bearing seat, increasing the smoothness and durability.
