Sonic Ergo 50a aero extension

The Profil Design Sonic Ergo 50a extensions have been designed to offer all cyclists looking for an aerodynamic position, optimal air penetration.
Thanks to its many adjustment possibilities, the Sonic Ergo 50a easily adjusts to the position of your choice.
Their raised shape offers a significant inclination of 50° (90mm) and thus allows a natural hand position requiring almost no wrist flexion. Heavier than the aluminum version due to a reinforced structure, this model has improved ergonomics for even more comfort.
