For high end, we use High Performance 7005 aluminium alloy which has a very low density combined with high strength due to the special alloy and the hardening heat treatment. By triple butting or even quadruple butted tubing, aluminium tubes are reinforced where required and reduced where possible. In addition we use Special tube shapes, manufactured with Hydroform technology to better cope with the directional forces. The low density and high strength as well as the butting and the Hydroform technology enable us to make high performance frames with an ultimate level of stiffness.

This new steering tube design is more rigid and generates a more secure ride feel even in difficult terrain. Due to the direct power transmission the greatest possible steering precision is generated. With the larger fork shaft the forks become more rigid. At the same time weight is saved due to the absence of bearing shells as the lower bearing is fully integral. On CUBE carbon models the upper bearing shells are also directly in the frame, so that once more a few grams are saved.

For the first time in 2011 we are also manufacturing top tubes and seat tubes of the new AMS ALU models using this hydroforming process, which has proved its worth. In conventional hydroforming processes this custom form and technical advantages cannot be achieved. As this manufacturing method reduces the number of welds, the weight is reduced with a simultaneous increase in stability.

With press-fit bearings, the outer bearing ring is pressed directly into the frame housing and not screwed-in as usual. With its wider housing, the down tube and the chain stays are joined with the full width. Because the width of the housing is a parameter in calculating the stiffness, every millimetre of additional width gives a significant improvement of lateral stiffness, whilst retaining the comfort-bringing resilience of the chain stays.

These specially designed seat stays fulfil many roles. At the upper end at the connection to the seat or top tube they run laterally oval and thus offer vertical flexing and so ensure comfort. At the lower end they are extremely vertically oval and offer the minimum drag area to the headwind.

To protect our high-end aluminium frames, they are built with the CUBE Frame Save System replaceable derailleur hanger. The thread is in the hanger and not in the frame as usual. In case of a crash, this hanger can be easily and quickly replaced by a new one.

Joints in high-quality aluminum frames are specially finished via this method and so create the impresssion of seamless tube design. This generates the visual effect of molding and ensures high load-bearing capacity.

Internally routed cables offer many advantages: clean appearance, cables are protected from dirt and therefore have a considerably longer life and the not required external housing saves weight.

Our bicycles with RFR-geometry stand out by their sports character. The riding characteristics, rider comfort and rider safety in particular are taken in account for each individual bike category.

The colour of our aluminium frames with Eloxal finish is reached by anodising (a chemical process). After this treatment, the aluminium is 1000 times more scratch-resistant than before.

On the high performance frames, graphics and texts are laser-cut into the material which makes them indestructible for a lifetime.
