ONE-K RD-X carbon wheelset tubeless 23mm DUKE/NON+ 48/36mm

With its 23 mm wide rim, the RD-X ensures first-class riding comfort and optimum grip, even on challenging surfaces. Ideal for long tours, it offers maximum reliability and stability on all surfaces. With a permissible system weight of 120 kg, the RD-X is ideal for riders of all sizes and weights.

Outstanding Technology for Demanding Riders
The 24-hole carbon rims provide the perfect balance between weight and stability. A low rim height ensures optimal climbing characteristics, while a higher rim offers aerodynamic advantages. The specially developed NON+ Components hubs are extremely lightweight and enable perfect integration of the innovative spoke system.

RAW Titanium vs. DLC-BLACK
The titanium spoke suspension is not only a technical highlight but also a visual eye-catcher. Two options are available for a customized finish:

• Diamond-Like-Carbon (DLC) coating for an elegant dark look and improved surface properties
• Raw Titanium for a minimalist, technical-puristic aesthetic

About ONE-K
ONE-K is a spin-off from the Leibniz Institute for Composite Materials, specializing in ultra-lightweight road bike wheelsets. The unique spokes are made of high-strength fibers in an epoxy matrix, making them extremely durable, damping, and power-transmitting.

The patented manufacturing process enables the production of spoke stars from a seamless fiber tape, which is integrated with the hub and rim without mechanical connections. Titanium nipples ensure precise tension and perfect truing. Standard rims can be used, while specially adapted hubs from established manufacturers integrate optimally into the system.

Developed and manufactured in Germany, ONE-K stands for top-tier engineering, sustainability, and innovation – delivering the ultimate riding experience.
