ALCHEMIST rim 28" Ultra Race Z580 Disc UD-Carbon shiny | 24 hole
The alchemists searched for the philosopher's stone in order to be able to produce gold. As we know today, this was a foolish and never achievable endeavor. As a producer of bicycle parts, Alchemist has similarly lofty goals, but unlike its medieval predecessors, it achieves them.
Alchemist Ultra Race carbon rims are manufactured in Italy. High-end Toray T1100G UD carbon fibers are used as the base material. These are lighter, yet more resilient than conventional fibres 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 rigid rim. The high impact resistance is achieved by the special Impact Performance (IP) processing of the fibres. This prevents delamination of the layers and thus also resists punctual impacts from the outside. Technical features such as reinforced spoke holes, hybrid rim flanges and a 58 mm high asymmetric 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 on conventional designs. This enables greater compatibility between tires and rims. In addition, the stability of the tread is increased in the event of punctures. Thanks to the newly developed production process, subsequent machining by 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 surfaces, the highest quality carbon fiber on the market and first-class features are combined in these rims.
