ALL SILVER BOOMS ARE MADE FROM 7075 HIGH-TECH ALUMINIUM IN HIGH-QUALITY BONDED TECHNOLOGY. THIS MATERIAL USED PREDOMINANTLY IN CYCLING GIVES THE TUBES SIGNIFICANTLY MORE STIFFNESS.
There is also the new combination of a round tube in the front area (holding forces act obliquely downwards, so it is stiffer around here) and the OVAL TAIL SECTION (horizontal sail pull, thus the oval tube is stiffer here). 
Together with the hardened front arch, this results in enormous hardness and durability.
