Ultra Racing meticulously choose each material to guarantee optimal performance and safety. Brackets are crafted from steel plates measuring 4mm to 5mm in thickness, while the hollow steel tubes and oval tubes range from 1.2mm to 1.6mm in thickness. These materials are thoughtfully selected to ensure that bars maintain rigidity and strength, preserving consistent geometry at all times, while also being designed to crumple during an impact for safety reasons. Rest assured, all raw materials undergo rigorous testing, yielding satisfactory results.
