Tune Lightweight piece, seatpost, aluminum, length 340mm, diameter 27.2mm, black - black - noir

Product information 'Lightweight seat post'
We encounter the inspiration for our lightweight piece time and again in everyday life, for example in the form of half-timbered houses, tower cranes and bridge constructions. The most impressive example of this construction is the slewing tower crane. A narrow crane tower with a - relatively - oversized boom. Who wasn't impressed as a child by the fact that the crane doesn't collapse or fall over? This design is made possible by a special arrangement of the struts, among other things, and a saddle support undergoes a bending load during operation which generates tensile and compressive stresses. The truss structure is ideally suited for this type of load and achieves the same stability at a significantly lower weight. It also has good clamping properties. In practice, the lightweight piece impresses with a high level of self-damping for road and gravel use. Our light piece is based on this type of technology. The cut-outs based on this principle allow us to save a whopping 40g in weight without sacrificing stability. We even accept a significantly longer milling time on our CNC machines for this.

Length and color
The support is available in two lengths (340mm and 420mm) and in our familiar colors* (blue, green, gold, orange, red, silver, black).
