ALCHEMIST rim 28" Ultra Race Z580 disc UD carbon glossy | 24 holes
The alchemists were looking for the philosopher's stone in order to be able to produce gold. As we now know, this was a foolish, unattainable endeavor. As a producer of bicycle parts, Alchemist has similarly high goals, but unlike its medieval predecessors, it achieves them.
Alchemist Ultra Race carbon rims are made in Italy. High-end Toray T1100G UD carbon fibers serve as the starting material. These are lighter, but still more resilient than conventional fibers and are held in shape by a break-resistant nanopolymer synthetic resin, which is also used in Formula 1 cockpits, resulting in a resilient, torsionally stiff rim. The high impact resistance is achieved through the special Impact Performance (IP) processing of the fibers. This prevents delamination of the layers and thus also withstands isolated external influences. Technical features such as reinforced spoke holes, hybrid rim flanges and a 58 mm high asymmetrical aero profile leave no potential untapped.
Hybrid rim profile
Hybrid is a concept of hooked rims for road bikes and gravel rims. The hook on the rim flanges is much smaller than in conventional designs. This allows for greater tire and rim compatibility. In addition, the stability of the profile is increased in the event of punctures. Thanks to the newly developed production process, subsequent milling and the use of additional carbon fiber layers are unnecessary.
Ultra Race series
The Ultra Race series means maximum performance without compromise. Competent craftsmanship, unique finishes, the highest quality carbon fiber on the market and premium features come together in these rims.
