When it comes to the Top Tube, less is more. Through the integration of the specially adapted tube shoulder into the cap, the head plate of the cap is replaced leading to weight savings of >70% in the cap. Furthermore, the tube wall is at maximum 0.35 mm thin instead of the usual 0.50 mm. To further save primary material, (transparent) post-consumer recycled plastic can be used. For improved recyclability, the cap and tube are made of PE. The Top Tube is ideal for product lines with different tube sizes: ∅ 50 & 40 mm are currently implemented, ∅ 35 & 30 mm are planned for next year.
