The Profile Design NeoSonic / Ergo / 45AR Aerobar is an adjustable DL aerobar extension that allows you to assume a more aerodynamic and subsequently faster riding position.
With the Neosonic bracket and its 25 mm adjustability, this aero extension makes the Sonic Ergo 45AR an excellent addition to your road, gravel, or touring bike. Compared to the Sonic version, this bracket positions the armrests behind the handlebar, somewhat shortening the reach.
It also provides up to 80 different installation options for the armrests, which can be shifted forward, backward, left or right as needed. The armrests have a concave shape and EVA foam padding, providing your lower arms with comfortable support.
With the Profile Design NeoSonic / Ergo / 45AR aerobar extension set you can ride in an aerodynamic position for more speed and better conservation of energy.
