The Supersonic bracket (previously know as the J5) is the first and premier model of the new generation Profile Design brackets.  It offers easier adjustments and a greater fit range than anything that came before it.  Paring this bracket with the ergo armrest offers industry leading fit options and greater comfort.  With the 35c extensions this aerobar is suited to riders who wish to adopt an aerodynamic 'arrowhead hand position.
