Geometry, size selection



An aluminum alloy containing Mg2S silicides as its main additive is referred to as Alloy 6061. Class 6000 alloys are highly workable, weldable, and machinable.

Všetky rúrky našich rámov sú na zákazku prispôsobené na základe pevnostných analýz a potrieb dizajnu celého bicykla.

Tepelná úprava rámov zahriatím na teplotu 130 °C po dobu niekoľkých hodín je proces obnovenia mechanických vlastností, ktoré boli stratené počas zvárania.

The advantage of a tapered headtube is that it allows for greater bearing surface and stiffness of a 1.5“ steerer and lower bearing surface while reducing weight and allowing the use of conventional 1 1/8“ threadless stems.

Increased efficiency in the transfer of energy to the rear wheel is referred to as HP-C. This technology has been incorporated into the elaborate rear construction of all DEMA carbon frames.

This technology offers the possibility to use heat processed 3D frame endings with interesting shapes. Their advantage, compared to milled endings, is the increased strength of the material.

High Tensible Steel – vysoko pevnostná oceľ je odolný materiál ideálny pre stavbu lacnejších bicyklov.
