The ASC Pro reintroduces Profile Design to the one-piece extension category that we first pioneered nearly 20 years ago with the Sonic Stryke.
Designed for riders who demand performance and comfort, the ASC Pro is a sleek, high-performance solution for time trials and triathlons. Built with aerodynamic precision, these extensions deliver the low, aggressive riding position that shaves seconds off your times. The integrated one-piece construction ensures rigidity and responsiveness, while the ergonomic design keeps you comfortable during long efforts. Whether you're chasing personal bests or competing at the highest level, the ASC Pro combines decades of engineering expertise with modern performance standards.
Features
- 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.
- Combines the comfort and aerodynamics of a custom bar with the flexibility needed for optimal position adjustment.
- Built with a 15° base angle, this can be adjusted by 10° and 25° with tilt wedges.
- Compatible with the A3 Riser system, or an A2 Riser with the addition of the A2-A3 adapter.
