With the Supersonic Ergo 4525C aero bar, Profile Design has another highlight in their range of handlebar extensions. The versatile Supersonic brackets of the lightweight FLYT system carbon extensions are the new generation of the popular Sonic brackets. They feature an easier to reach extension clamp and allow you to fit a BTA hydration system (product code: 2281514). Increased setback makes the Supersonic especially suitable for racers who prefer to have their armrests well behind the base bar. In combination with the Ergo armrests that offer outstanding ergonomics, you get versatile adjustment options for maximum comfort. The aerodynamic and flexible overall package of the aero bar is topped off with Profile 4525C carbon extensions, providing a 45° upsweep in the first section and a 25° bend in the grip section. In combination with a 7.5 mm lateral shift per side, the bar thus offers several comfortable grip positions, so that the rider may choose and switch between a compact riding position with a low grip position and an aerodynamic riding position with a high grip position. Therefore, the Profile Supersonic Ergo 4525c aero bar is a reliable partner when trying to beat your personal best time.

This gives you an uncomplicated basis to individually adjust your riding position. No matter if you are a hobby cyclist or a professional bike fitter.

Supersonic Ergo 4525C Aero Bar

Ich habe wenig Erfahrungswerte und kaum Vergleiche, aber ich bin sehr zufrieden und fühle mich sehr wohl mit bzw. auf dem Lenkeraufsatz.
Ich war auf der Suche nach einer weiteren Position auf dem Rad für lange Touren und bin froh, den Aufsatz gekauft zu haben. Die paar km/h mehr sind natürlich auch ganz fein.
