Nothing happens without a reason.
To understand how the Racing Zero Carbon DB we see today became possible, we need to look back at the evolution of Racing Zero and its familiar character.
By respecting the family's core principles and interpreting the world of disc brakes, Fulcrum's R&D department has met a particularly complex challenge: evolving while respecting a history, to create a truly astonishing product.
It starts with the underlying concept: carbon and aluminium together create a unique combination, introduced on its rim brake sibling, to enhance responsiveness and stiffness for precise, confident handling.
The 30 mm-deep profile highlights its lightness on climbs, while the wide 19 mm internal rim width creates an ideal support base to push handling limits to unprecedented levels. Innovative technologies, such as the new ARC coating that creates elastic reinforcement at the spoke junction, help achieve this. Unrivalled performance, technology and innovation.
Racing Zero Carbon DB excels whenever gradients reach double figures, where power transfer becomes essential.
It excels on descents, because the wide rim and support from the aluminium spokes help give you the confidence to push a few metres further.
Racing Zero Carbon DB adapts to a wide range of situations with style and character, becoming, or rather confirming its place as, the ultimate benchmark for all-round wheels.
All that remains is to gaze at it and imagine the next summits to reach in the saddle, then try it on the road and find yourself climbing at speeds you have never experienced before.
