It allows for precise adjustment of the extension angle, offering a customised position suited to every body type. Made from CNC-machined aluminium, this kit guarantees exceptional strength and durability whilst remaining lightweight. The high-quality anodised finish ensures enhanced corrosion resistance and a sleek appearance. The mounting system is compatible with a wide range of aerobars, thanks to M5 or M6 bolt options. The kit includes two extensions (left and right), as well as all the screws, washers and nuts required for installation.
