Bergkönig with sensational 790 gram weight!
For 2017, the flat tube rim and the success model of AX Lightness, the Ultra 24T, were completely revised. The successor, the ax 25T, is now 25 mm deep and still weighs under 200 grams with a width of 22 mm, so that a wheel set weight of 790 grams is realized.
With the ax 25T, the integrated logos are littered in the rim and now have improved aerodynamics thanks to their modified shape. The brake behavior has also been improved by means of a stepped and mechanically reworked brake edge even in difficult conditions.
The Ultra 25T wheel set is a true mountain and kite kite, as it has already proved during numerous races, whether it be an alpine marathon or a mountaineering trip.
Despite its sensational weight, the Ultra 25T has exceptional stiffness and stability values ??that give it a driver's weight limit of 100 kg, making it not only uphill, but also downhill to a safe bench and an absolute weapon.
The wheels are developed in Germany by AX Lightness and produced under constant quality control.
It is prudent to ensure that the laminate made of highly resilient carbon fibers is always optimally constructed. Damage to the fibers is avoided in order to achieve maximum stability with the lowest possible weight. The holes required in the rim are therefore not drilled through the fibers, as in the case of more favorable rims, but are laminated with reinforcements ex works. This greatly increases the workload across all process steps, but leads to a much better product, the result: nipple extraction forces of five tons - that is far more than any spoke, nipple or hub body ever could handle!
In the center of the wheels are hubs of extralite. These masterpieces of lightweight construction from Italy are optimally adapted to loads by means of modern computer-aided development tools. At the same time, superfluous material is saved and stable plastic is used in less heavily stressed areas. The free-wheel mechanism is based on a toothed-disk principle, in which all teeth of the toothing are always gripped and the driving torques are transmitted.
For optimum deceleration with the least possible wear, brake pads are recommended which are matched to carbon brake flanks.
