There are innumerable challenges in road cycling. One of the most emotional challenges certainly is the ride uphill. An ultimate experience every time, both physically and mentally.
There is hardly another place than in the mountains of the world of cycling where the cyclist and the material reach their limits more. There, weight is mercilessly for or against you.
The wheelsets play the probably most important key role.
And this in two respects: firstly, the system weight must be low, secondly small rotating masses accelerate much easier.
ax-Lightness has combined its entire lightweight construction expertise in the rims of the "Ultra" wheelset. This results in a sensational weight of less than 200 grams per rim. With no limit on spoke tension and air pressure. Consequently, the entire potential of the spokes and hubs can be used to make this wheelset light, stiff and therefore safe.
Together with the Extralight hubs und Sapin X-Ray spokes, the wheelset even weighs less than 800 grams.
