PROFILE DESIGN - ASC PRO 43 AEROBARS
The ASC-Pro is the new, top level integrated extension from Profile Design. It has been carefully shaped to smooth airflow around the arm and minimise flat surfaces presented to the wind. The extension and grip are based on the 43ASC so will be familiar to any users of those extensions. The armcup is a highsided design to provide support for a narrow elbow position. Full carbon construction and a pared down bracket design work to improve both aerodynamics and the weight compared to standard brackets and extensions.
The ASC-Pro will be available in three sizes - 325mm, 350mm & 375mm. The natural angle of the extension is 15 degrees.
Tilt wedge kits can be purchased to alter this:
- Negative wedge kit: -1,-2,-3,-4,-5 as individual pieces
- Positive wedge kit: 1, 2, 3, 4, 5 as individual pieces.
They can be stacked to achieve a 25deg extension angle.
There are two bracket options:
- 5mm offset - this gives the 170mm and 150mm armrest width positions
- 15mm offset, this gives the 190mm and 130mm armrest width positions
The brackets can also be flipped fore-aft to achieve a 20mm reduction in reach. If you use the rearward position you will also need a 10mm adaptor riser.
