AX Lightness Zeus carbon Road stem 1
The Zeus provides convincing performance with divine power.
All of our fibre composite material expertise comes to fruition here. And it's needed here because stems are subject to all kinds of force and tension. In addition to easy-to-handle flexural moments, torque and locking force must also be controllable. These requirements are reflected in a manufacturing method developed especially for this cycle component that maximally leverages the potential of the composite materials.
It is characterized by the uninterrupted fibre pattern that extends from the handlebar through to the fork clamp via the parting planes of the tool mould. The stem has no weak points and scores with consistent stiffness across its entire length. This is most easily seen in out-of-the-saddle pedalling. Consequently, the clamp is responsible for the impressively low weight of the stem, whose constructive minimalism easily and effectively keeps the fork and handlebar in check. These integral concepts are the only way to achieve these weights and optimal distribution of tension within the compound, which is why threading is a side effect that must be accepted when assembling the handlebar.
Innovative stress miracle
Thanks to the carbon material, the innovative construction is exceptionally stable yet feather-light – a stem for a true STW (stiffness to weight) miracle. Intramodular fibres are used intentionally as the stem is a safety-related component that only shows safety potential through its fibres and a matrix of premium quality that also meets the requirement of achieving minimal weight. In conjunction with a special epoxy matrix and unlike their ultra modular or ultra-high modular counterparts, they demonstrate a more forgiving behaviour at rupture and do not exhibit abrupt or brittle breakage characteristics. Loads are distributed across larger areas and strain concentrations are reduced. Years of conscientious development and the latest inspection and testing procedures have so convinced us of this product's performance that we even use it in MTB.
