ONE-K is an innovative manufacturer of
high-quality bicycle components from Freinsheim in Rhineland-Palatinate, specializing in the development and production of
ultra-light carbon wheels. The company was founded as a spin-off from the Leibniz Institute for Composite Materials at RPTU Kaiserslautern-Landau and brings together the expertise of three cycling enthusiasts and inventors. Their goal is to develop the world's
lightest bicycle spokes while ensuring top performance and quality.
One of ONE-K’s outstanding innovations is the patented spoke system made from fiber-reinforced composite. Using a special manufacturing process, multiple connected spokes are created from a continuous fiber band. Small loops at the end of each spoke enable the connection to the
hub and
rim. This design allows for up to 60% weight reduction compared to conventional steel spokes without compromising stiffness or durability.
ONE-K’s product range includes various
wheelsets for different applications. The RD series is aimed at road cyclists and offers models such as the RD-S, an all-rounder weighing from 1,124 grams with a 21 mm internal rim width, and the RD-X, featuring a 23 mm wide rim for increased riding comfort, starting at 1,034 grams. Both models have a maximum system weight of 120 kg and are suitable for ambitious hobby riders as well as professionals.
For gravel enthusiasts, ONE-K offers the GL-S series. These wheels combine agility and stability, optimized for off-road use. With a 25 mm internal width and a 35 mm rim height, they provide excellent comfort and grip on unpaved terrain. The weight starts at 1,154 grams, with a maximum system weight of 120 kg.
A distinctive feature of ONE-K wheels is the use of
high-quality components. The hubs, sourced from renowned manufacturers like NON+ Components, are specifically designed to work with the ONE-K spoke system. The rims, developed in collaboration with French specialist DUKE Racing Wheels, stand out for their aerodynamic design and high stiffness.
ONE-K places great importance on quality and durability. In addition to the statutory warranty, the company offers a voluntary 3-year warranty against material and manufacturing defects. There is also a generous crash replacement program to support customers in case of damage.
By combining innovative technology, high-quality materials, and precise manufacturing, ONE-K sets new standards in
wheel construction, offering both recreational and professional cyclists products that excel in weight, stiffness, and riding comfort.
