IF YOUR DETERMINATION KEEPS YOU GOING EVEN ON THE COLDEST, WETTEST WINTER DAYS, AND THE MUD DOESN'T DETER YOU FROM COMPETING IN THE SADDLE, ALCHEMIST WHEELS WILL ACCOMPANY YOU ALONG THE MOST CHALLENGING CYCLOCROSS TRACKS AROUND.

PRO RACE SERIES


Design ability, a knowledge of composite materials and craftsmanship: these are the differentiating factors that have allowed us to redesign the Zirconium wheels, improving their performance and striking the best balance between stiffness and lightness.

These totally tubeless wheels, which have a height profile of 30 mm and 40 mm, are mounted with Sapim CX-Ray spokes on aluminium or carbon hubs. The race version comes with ceramic bearings. In addition to the 2 mm offset, which ensures the correct tensioning between both sides and creates greater lateral stiffness, the Zirconium line is characterised by a concave/convex profile, created based on a study of the NACA M18’s aerodynamic profile. This solution – which is completely unique – was adopted to compensate for the load-bearing effect that is generated by a non-symmetrical wheel profile.

Conversely, the incredible torsional stiffness is ensured using the exclusive Diamond Technology, that is, by positioning the unidirectional fibre between the perforations and the spokes in a rectilinear fashion. This provides the internal circumference with its multi-faceted diamond appearance.

The Zirconium wheels adopt the “Bubble” technical solution, in which the carbon fibre is oriented in the direction of the spokes’ traction, increasing their resistance to tearing by 18% around the nipple area, without adding thickness and weight.

PRO TRAINING SERIES


The Pro Training RT38 tubular tires, which are configured with 24 spokes with a flat profile and the new hubs with the 26HT system, are fast and reactive.

They are designed for optimal performance on cyclocross circuits, thanks to their low weight, 38 mm profile, premium-quality carbon fibre and their components.
