Profile Design Sonic/Ergo 4525A Triathlon Extenders

The new Profile Design Sonic mount combines with the Ergo armrests to offer both a wider range of adjustments and increased comfort for the cyclist thanks to a support curve to secure the armrests. The Sonic / Ergo set is designed to have a minimal frontal area to create as little aerodynamic drag as possible. Sonic / Ergo offers a range of adjustments for this purpose.

The 4525A extensions offer a dual angle. The first section offers a 45° angle, followed by a 25° angle in the second section, and a lateral offset of 7.5 mm, allowing the cyclist to move their hands closer together or further apart depending on their preferred position.
