Profile Design Subsonic ERGO 39A Aerobar

The Subsonic/Ergo is designed to achieve a lower stack height than standard aerobars, without the added frontal area of a below the basebar extension clamping system. This improves aerodynamics and the fit range. The Subsonic/Ergo/39a aerobar combines the low stack Subsonic bracket with the arm hugging Race armrest to offer an industry leading fit range oriented towards low, narrow positions. The 39a extension offers a comfortable 39 degree angle with a 87mm rise. The Ergo armrest has been designed to tightly cup the riders arms – facilitating a narrow position and increasing control at speed. There are 80 distinct position options achievable just by moving the armrests. Combine that with the risers and this bar offers 1200 possible configurations.
