Profile Design Subsonic Ergo 35a Aerobar - 31.8mm Clamp

The Subsonic/Ergo/35a aerobar combines the low stack Subsonic bracket with the arm hugging Race armrest to offer an industry leading fit range oriented to wards low, narrow positions. The 35a extension offers a comfortable 35 degree angle with a 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 aerobar 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 Ergo armrest has been designed to tightly cup the riders arms – facilitating a narrow position and increasing control at speed.

Performance
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.

Fit Data
- Armrest offset: -85mm to -17.5mm in 7.5mm steps
- Armrest Width: 142mm to 272mm in 18.5mm steps (with Extensions at 100mm)
- Armrest Stack: The minimum is 40mm and the bracket is compatible with our existing risers which add up to 70mm of stack in 5mm increments.

The extension rotation can be easily adjusted using the shaft bolt. There is a 40mm range of extension length adjustment once the extensions have been cut.

There are 80 distinct position options achievable just by moving the armrests. Combine that with the risers and this bar offers 1200 possible configurations. As a clip on bar it is also possible to adjust the extension width and tilt easily. This is the most adjustable low stack clip-on on the market.

Who is it for
This bar is perfect for riders who wish to achieve lower positions than are possible with standard aerobar designs. Unlike other low stack bars it allows fine-tuning of the stack height so the rider is not limited to only one armpad height. With the Race armrests fitted it is tailored towards riders who intend to be low and narrow to punch the smallest possible hole through the wind.
