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.

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.

On polished and brushed aluminium and all HPC frames the logos and graphics are applied in multi-layer wet paint. We use this surface treatment technology mainly to save weight.
