With the Sonic/Ergo/4525a aero bar, Profile Design has a new highlight in their range of tri bars. The lightweight aluminium aero bar from the FLYT system combines the simplicity of the Sonic bracket and the ergonomics of the Ergo arm rest to offer versatile adjustment options and maximum comfort. The aerodynamic and flexible design of the aero bar is topped off by Profile 4525a extensions that offer a 45° upward bend that blends into a 25° bend in the upper section. In combination with the 7,5 mm angle, several comfortable grip positions are offered that allow riders to switch between a compact riding position with deep hand posture or an aerodynamically stretched position with high hand posture. Therefore, the Profile Sonic/Ergo/4525a aero bar is an essential partner when racing against the time.

Profile Design FLYT-System
With the FLYT system, Profile Design wants to simplify the process of fitting an aerobar to a rider. By using a combination of 3 brackets (Sonic, Supersonic and Subsonic), 3 armrests (Ergo, Boom (see below) and Race) and 3 extension options (35, 50 and 45/25), it offers 27 different combinations and more than 1000 adjustment options. This results in an uncomplicated basis for individual fit options - for hobby cyclists and professional bike fitters.

The Boom arm rests are similar to the F-40 arm rests. All other arm rests of Profile's F series are also compatible, yet not part of the FLYT system. The same holds true for all carbon and aluminium extensions of the T and V series.
