Technologies

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.

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 threaded bottom bracket technology is used in both carbon and duralumin frames. All DEMA frames using this technology feature a 68 mm wide bottom bracket housing with a BSA thread (1.370 x 24 tpi)
