The Profile Design 45/25 SLC Carbon Extensions are designed to provide multiple hand position options while maintaining a lightweight, high-performance setup. Featuring a dual-angle design with a 45° rise transitioning into a 25° grip section, riders can comfortably hold the extensions higher for a shrugged aerodynamic position or lower for a more open posture with improved head position and visibility.
A subtle lateral offset built into the extension allows hand position to be adjusted narrower or wider without excessive extension rotation, helping maintain cleaner positioning and avoid shifter interference.
Constructed using Profile Design’s Super Light Carbon technology, the 45/25 SLC combines reduced weight with improved integration, including compatibility with Aeroport Di2 adaptors for a cleaner electronic shifting setup. Ergonomic end caps further enhance comfort during long training sessions and race efforts.
Compatible with any aerobar system designed around a standard 22.2 mm clamp diameter.
Ideal for: riders wanting a lightweight extension with flexibility in hand position and modern high-hand fit options.
Bike Fit Note: Extension angle can significantly influence comfort, shoulder posture and aerodynamic sustainability. Multi-position designs can be particularly useful when fine-tuning a position or balancing comfort with performance.
