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
