PROFILE DESIGN SONIC ERGO ERGO 43a AEROBAR Bar Extensions

The PROFILE DESIGN SONIC ERGO 43a bar extensions offer top-level position adjustment options and greater comfort during your time trial efforts.

These extensions have been designed to present a minimal frontal area in order to create as little aerodynamic drag as possible. These bar extensions allow the cyclist to adopt an aerodynamic position despite a rather minimalist appearance.

The platform is designed to give cyclists the ability to find an optimal aerodynamic position with the capacity to hold that position during effort. There are 100 distinct position options achievable simply by moving the armrests. It is also possible to easily adjust the width and tilt.

The 43a extension features a curve designed to relieve wrist strain. The extension presses against the arm for improved aerodynamics without sacrificing wrist comfort. In addition to the neutral angle, the grips have a 7.5 mm lateral offset to allow the rider to fine-tune their hand position
