Nothing is born without a reason.
If today it is possible to think of a Racing Zero Carbon DB as we see it, it is necessary to rethink the evolution of Racing Zero and its character that everyone knows.
By respecting the cornerstones, the fundamental points of the family, and interpreting the world of disc brakes, the Fulcrum R&D department managed to complete a decidedly complex challenge: evolving, respecting a history, to arrive at an absolutely stunning product.
We start from the basic concept: carbon and aluminum together to create a unique combination, introduced on its sister for traditional brakes, to enhance reactivity and rigidity for the benefit of precise and decisive driving.
The 30 mm high profile enhances lightness when climbing, while the 19 mm wide channel creates an ideal support base for moving the riding limits to unprecedented levels. Innovative technologies, such as the new ARC coating that creates an elastic reinforcement on the spoke connection, contribute to working in this direction. Unparalleled performance, technology, innovation.
Racing Zero Carbon DB is exalted every time the climb reaches double digits, where transmitting power becomes an imperative.
It comes into its own when going downhill, because the wide rim and the support of the aluminum spokes help you feel capable of daring a few more metres.
Racing Zero Carbon DB adapts with style and character to the most varied contexts, to become, or rather confirm itself, the absolute point of reference among multipurpose wheels.
All you have to do is stare at it for a long time and imagine the next peaks to reach on the bike, then try it on the road and find yourself climbing at speeds you've never experienced before.
