Tune Lightweight seat post 420 mm

Product Information 'Light Piece Seat Post' The inspiration for our 'Light Piece' is something we encounter repeatedly in everyday life, for example in the form of half-timbered houses, tower cranes, and bridge constructions. The most impressive construction can be observed in the tower crane. A narrow crane tower with a disproportionately long boom in relation to its size. Who hasn't been amazed as a child that the crane doesn't collapse or tip over? This construction is made possible, among other things, by a special arrangement of the struts. A seat post primarily experiences bending loads during operation, which generate 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 'Light Piece' impresses with high self-damping during road and gravel use. Our 'Light Piece' is based on this type of technology. The cutouts following this principle allow us to save a substantial 40g in weight without compromising stability. For this, we even accept a significantly longer milling time on our CNC machines. Length and Color The post is available in two lengths (340mm and 420mm) and in our well-known colors (blue, green, gold, orange, red, silver, black).
