The Profile Design ASC Pro Carbon Extensions bring a one-piece carbon construction to a dedicated aerobar extension and armrest assembly. Each pair combines 43° grips with high-sided arm cups modeled on the Race+ shape, creating an arm-hugging layout from the grips back to the pads. Finished in matte black, the kit includes right and left extensions, an ASC Pro Switch Adapter, a 15 mm offset bracket, armrests, and extension pads.
Choose an extension length of 325 mm, 350 mm, or 375 mm. Because the one-piece ASC Pro extension body is not length-adjustable, selecting the appropriate length is an important part of dialing in the setup. Pair weights are 536 g for 325 mm, 549 g for 350 mm, and 569 g for 375 mm.
The ASC Pro uses a 15° base angle with 43° extension grips. Separate ASC Pro Tilt Wedges in 1°, 2°, 3°, 4°, and 5° increments can be used to adjust the default angle, including 10° and 25° configurations. A separate 5 mm offset ASC Pro Aerobar Bracket Kit is also available in place of the included 15 mm offset bracket, while the A3 Reach Extender increases pad reach by 32 mm on an A3-equipped bar.
These Profile Design aerobar extensions are compatible only with Profile Design A2 and A3 platforms. They work with the A3 Riser system; A2 Riser setups require an A2-A3 adapter. Di2 and SRAM AXS Wireless shifters are supported. An ASC computer mount, riser kits, tilt wedges, reach extender, and aerobar riser bolt kit are available separately.
