The Subsonic/Ergo/35a aerobar combines the low stack Subsonic bracket with the arm hugging Ergo armrest to offer an industry leading fit range oriented towards low, narrow positions. The 35a extension offers a comfortable 35 degree angle with a 80mm rise.

This bar is compatible with Profile Design riser kits to increase the stack without changing the relationship between the armrest and the grips. The Ergo armrest has been designed to tightly cup the riders arms facilitating a narrow position and increasing control at speed.

The Subsonic/Ergo is designed to achieve a lower stack height than standard aerobars, without the added frontal area of a below the base bar extension clamping system. This improves aerodynamics and the fit range.
