For 2017 the VIAL evo Ultra has undergone some key improvements: Groundbreaking weight, outstanding comfort and superb handling. Stiffness and stability are the absolute maxim of this thoroughbred racer.

The rear end has been completely re-designed. It has kept its asymmetrical shape which is largely responsible for its high stiffness, however the geometry has been altered to offer more clearance for modern wide rims and with wider tyres. Systematic reinforcement further increase the stiffness of the rear end and make it even stronger than before.

The more aggressive geometry allows for an even more sportive riding position. The other award-decorated properties, such as the balanced handling and the convincing comfort have remained positively untouched for the Race as well. The new rear end with increased tyre clearance and boosted stability now allows the use of wider tyres without issue as it currently is a trend in racing and that way also prepares the AX-Lightness for events such as the Ronde van Vlaanderen.

Created through State-of-the-art simulation and R&D procedures, combined with the most exclusive fibre material from the aerospace industry, allows the astonishing AX-Lightness Vial Evo ultra weight, stiffness, stability and comfort. Available as framset alone, Ubyk can create, through Probuild and truly personal custom building process, a superbike worthy of any rider or racer alike. Whether you build with AX's own superb cockpit or you choose other high end brands such as ENVE or THM Carbone, the possibilities are endless.
