Overview
There are a few factors to consider before purchasing the ASC Pro.
Please check the Compatibility Guide and the Buyers Guide.

The ASC Pro brings Profile Design back into the one piece extension category that we pioneered with the Sonic Stryke nearly 20 years ago.
The ASC Pro extension body is not adjustable so there are three sizes – 325, 350 and 375mm long.
The ASC Pro offers one piece carbon construction and arm hugging comfort from the 43° grips all the way back to the high sided arm cups modeled on the Race+ shape.

The ASC Pro combines the comfort and aerodynamics of a custom bar with the flexibility needed for optimal position adjustment.

The extension is built with a 15° base angle, this can be adjusted by 10° and 25° with tilt wedges.

The brackets are compatible with the A3 Riser system, or an A2 Riser with the addition of the A2-A3 adapter.


Accessory Options: Sold Separately
Need a computer mount? ASC Extensions is to be paired with a ASC computer mount.
Need to adjust your armrest position? The ASC Pro come with a 15mm offset bract but we offer a 5mm offset as well se below.
Know you stack height? The ASC Pro utilized the A3 riser platform. Before purchasing it is crucial to determine what your stack height may be and how many risers you will be using.
Know your extension angle? The ASC Pro Tilt Wedges are available in increments of
1°, 2°, 3°, 4°, and 5°, allowing precise adjustment of the ASC Pro’s default 15° angle.
The A3 Reach extender does exactly what it says on the label – increases the pad reach of an A3 equipped bar by 32mm.
