Profile Design Subsonic ERGO 39A Aerobar

Price
€260

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.

FEATURES

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.

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.
