The ASC Pro brings Profile Design back into the one piece extension category that we pioneered with the Sonic Stryke nearly 20 years ago.
Not being adjustable there are three sizes to choose from: 325mm, 350mm and 375mm long.

The ASC Pro offers comfort and aerodynamics comparable to a custom bar while retaining enough adjustability to allow position optimisation. The padding offers a consistent surface from elbow up to the wrist to maintain full contact with the riders arm.

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 modelled on the Race+ shape.

The extension is built with a 15° base angle, this can be adjusted by 10° and 25° with tilt wedges, ACASCPW1 and ACASCPW2.

The ASC Pro Kit come with a 15mm offset bracket that can be flipped and reversed to give two reach positions and two width positions.
