EXPERIENCE THE NXT ÆRA OF FIBERSPOKES

ONE-K stands for uncompromising lightness and precise performance. Developed for maximum efficiency while maintaining high safety and controlled riding behavior.

Engineering on a new level

The NXT-Æra wheelsets redefine performance through consistent aerodynamics and precise system integration. Based on the new ONE-K NXT Fiberspoke system with integrated spoke nipples and proprietary ONE-K carbon rims, the rim geometry is specifically tuned to the NXT spoke system. The result is a wheelset that combines high structural stiffness with stable aerodynamic properties, designed for low weight, high efficiency, and a direct, controlled riding behavior, even under high load.

NXT ÆRA-Serie

With the NXT ÆRA Series, ONE-K presents a world first in wheel construction. For the first time, the ONE-K NXT FIBERSPOKE system is used as the basis of a newly developed wheel concept. Integrated nipples optimize aerodynamics and contribute to further weight optimization. Despite the high structural stiffness of the wheelset, the total weight remains under 1 kilogram, a new benchmark in this category. The modern rim geometry ensures calm and stable riding behavior even at high speeds and in crosswinds. The high-performance hubs are equipped with a patented conical freehub body that provides up to 400 % more engagement surface than conventional ratchet systems. A large hub flange and CeramicSpeed Coated bearings ensure optimal power transmission – performance consistently carried through to the end.
