The Subsonic/Race/35a aero bar combines the low stack Subsonic bracket with the arms hugging Race armrest to offer an industry-leading fit range oriented towards low, narrow positions. The 35a extension offers a comfortable 35-degree angle with an 80mm rise. This is the only low stack clip on in the market that maintains the pad to grip angle as the bar is stacked up
Subsonic not just another aero bar bracket. It brings our next generation fit range to a low stack bracket design. This allows the bar to use our riser kits to increase the stack without changing the relationship between the armrest and the grips. The Race armrest has been designed to tightly cup the rider's arms – facilitating a narrow position and increasing control at speed.
